Well my attempt to wait it out failed. The flush I did seemed to do very little to help the problem. In fact it got worse. Since I've now partially flushed all of the other plants as well, they are starting to develop the same symptoms. I didn't flush them as heavily as the Incredible Bulk, and their problems are not as sever as hers.

I am now operating under the assumption that this is a calcium/magnesium deficiency. There are purple stems everywhere, the stem veins are still green, and it seems like the chlorophyl is just drying up. Here is a photo of the Incredible Bulk with the top two most burned leaves removed.

I treated them today with a 1/2 strength nutrient solution with CalMg added and a small amount of superthrive. The Cal Mag I added at 1 tsp/gallon. Superthrive was at 1 drop per gallon.

I don't know what the pH was because I didn't check it. Yup, I'm testing Canna out on their claim because I paid a ton of money for this soil and nutrients, so they better work the way they're supposed to. Also because why not? The worst that can happen is that they get worse. Or die. Whatever, I'm tired of screwing with it so let's see how the easy method is.

I also defoliated them. I can't honestly look at those fan leaves any more, and I was planning to do it sometime this week anyway. So, they need to recover.

It's a little hard to diagnose plant issues with LED lighting but I think that your PH is too low which is locking out calcium, magnesium and phosphorus, which would explain the interveinal burning and the purple stems (beyond genetics anyway) too.

Now that you've flushed, it's time to feed at your next watering. Aim for a pH of 6.5or 6.6 but try not go lower. Watch for signs of spreading; if the spreading stops, that was it. The purple stems might never go back to green and the burnt parts might need to be trimmed off (don't go overboard) since that won't recover either...

Thanks SME,

I think you're right. The burning pattern and purple petioles are the main symptoms I'm thinking.

Since fertilizing with 1/2 strength nutes, they seem to be doing a little better. The incredible bulk is still suffering what looks to be the same deficiency on its new growth leaves - they're all yellowish. Could be nitro too, but I'm still assuming CalMg.

As such, I'm thinking the incredible bulk may be lacking in nutrient quantity past whatever lockout issues she had. I'll be watering the rest of the plants, then increasing the CalMg dose in the remainder of the solution and apply it to the incredible bulk. We'll see how that goes.

As they're getting bigger, they're obviously using water at a faster rate, and I think they will be ready again tonight. I'll feed them 3/4 strength canna nutes, full dose (2 tsp/gal) CalMg and 1 drop/gal superthrive.

I'll post some pictures of them this evening or tomorrow.

Quick question unrelated to this grow, but to my next:

I just recently renewed my med card and have an increased plant count and with it the ability to grow Sea of Green style, instead of SCROG like I have before and will with this grow.

My question to all the experienced SOG growers here, how many plants would be ideal for my 3.5x3.5 growing space? Also, if these plants I'm growing now were grown SOF style and crammed in there, they'd be in flower already, right?

That's the primary reason I'm interested in SOG, time saving, and the yield of a SCROG.

I consider SOG to be the most efficient grow method but plant densities vary from 1/sqft to 4 or more/sqft and how long they veg depends on how tight you pack them in. With high density SOG you'd have little to no veg time. in a 3.5x3.5 I'd say between 9 to 50 plants would be about right.

With SOG you want to use sexually mature clones from the same genetic mother not seeds and not mixed genetics under one light.

Thanks SME for the information on SOG. I'm definitely planning on making a mother out of the strongest plant of my next seed batch, and clone off of her to get my SOG going.

Yesterday the leaves were looking a little better than before, but still spotting a little with what I'm still assuming is CalMg deficiency or lockup due to pH issues I had. All of the plants were pretty light so I watered them with the same 3/4 strength solution I used last time. That is 3/4 strength canna nutrients, 100% CalMg (2 tsp/gal) and 1/4 tsp superthrive, pH adjusted to 6.5. TDS: 800ppm.




After watering, I removed the most damaged leaves on all of the plants.


The plants height has evened out quite nicely, they are sitting at an average 7" tall right now. The topped plants new tops seem to be forming nicely as well.



All these pictures are from last night. I haven't looked at them yet today, if they look remarkably different I'll most more pictures of them. Otherwise, I have a transplant coming up, then one more defoliation, recovery, and then I'll kick them into flower. Hopefully. I'm thinking 2 weeks...? Maybe 3.

Thoughts or advice are always welcome. Thanks for stopping by!

With LED; I think flowering at 10-12" is a better bet than waiting a specific amount of time.

Well, I'm stumped, perplexed, and way annoyed at this point. The symptoms haven't gone away, and the new growth on 4 of 5 plants are showing the same chlorosis. My pH at the last 5 waterings was 6.5. Runoff has been between 6.4 and 6.7. EC was between 800-950. Not too much superthrive, CalMg, or regular nutes.

So I am kicking myself almost hourly for not making my own soil, and going with Canna, somehow thinking it'd be easier and grow a better product. What a fool I was.

To make matters worse, I didn't water them last night, and I knew I should have. Tonight, the Incredible Bulk looks really thirsty, but I'm sure she'll perk up after I water her.

Here are pictures:




I am completely stumped as to what their problem continues to be. At first I thought CalMg due to pH. But I corrected that to 6.5. Then I thought not enough CalMg, so I upped the dose to 3 tsp/gal. TDS didn't go crazy, but still they're looking the same. This is so frustrating, I never had this problem with DWC, nor do I think I would be having it if I had mixed my own soil.

So to reiterate, here are my environmental conditions:
Temp: 84 F steady
Humidity: 45%
pH: 6.5
TDS: 800-950ppm
CO2: 1250ppm
Photo: 24/0

And I think I may have changed my mind again about which plant won't be transplanted, and I'm now thinking the Incredible Bulk. As much as I want to grow this strain, she has been the biggest pain out of all of them so far, and I have no intention of messing with her all the way through flower if this is how she's going to act. The Pineapple Chunks have shaped up pretty well, and they're showing less chlorosis than the IB. Same for the Money Makers. Money Maker #2 is showing no signs whatsoever.

Thanks for stopping by! Please excuse my frustration.

hey MC,

wish i could help but don't know crap about soil growing. seems like what you are doing is correct though

instead of dumping the Bulk, is there a way you could transfer her to a single bucket DWC?? a long time ago i used to get my clones in solo cups of soil and i'd dump the soil, rinse the dirt off the roots and pop her in a net pot with hydroton. the few that i did that way all survived. just a thought to keep her alive and well...

Hi RKY,

Thanks, I know! It's a beyotch of a problem! I sure can't figure it out. I did pick up some dolomite lime today, and I'll be transplanting BY SUNDAY at the latest so I will amend their soil with that to buffer pH in the future. If they stop showing this problem after transplant, I can't tell you what a happy man I'll be.

As far as the incredible bulk, I would probably put a lot more effort into keeping her if my plan from he beginning wasn't to have just 4 plants. I'm still planning to SCROG, so I want to make sure I have adequate room for 4. My previous grows in DWC were done with 1 plant in a 3'x3' module, similar to the one I'm using here. Having 4 plants in a 3.5'x3.5' space... I'm guessing a little at when to flip.

Also my very very first grow, I tried to pull some grocery store herbs out of the soil they were in, clean the roots and put them in my ebb/flow hydro table. It didn't go so well... Like almost instant death after a day. Also I don't have any more GH nutes, and blah blah blah... She's just not worth the hassle really. But, man, if you've successfully transplanted a soil plant to hydro... Ever ... Then so much props. I mean seriously.

Hoping to transplant tonight, but if not it'll be Sunday. Timeline is, transplant, recovery, flip. Supposing that makes them 10" tall at flip. SCROG on top of that, and they'll each have 1.25'x1.25' to grow into while flowering... Being about 10 inches tall before SCROG screen... And another 25"-30" of stretch... Wow they might really get to big for my screen already. What do you think?

Thank you!
