I apologize for not updating last week. i'll just say things have been kinda hectic in my life - nothing bad, just busy.

in the last 2 weeks, a few problems have presented themselves.

1. foliage has been affected by my nutrient toxicity. there are dry, dead spots between veins on some of the leaves near the top. i'm pretty sure its a combination of the toxicity from earlier followed by lockout caused by the nutrient overload. plant is still stong, sticky, and smelly. I don't think this will be an issue in the future b/c I have adjusted my nutrient regimen.

2. Mold! I noticed a small, dead water leaf on my largest top. I pulled a bud away and saw quite a bit of mold around the dead foliage. I immediately pruned the affected area and began a water cure. I will use this as personal and see if water curing helps with removing mold. I checked other large tops and they are mold free. just an FYI - I never went back to foliar feeding so that wasn't the issue. I believe it has to do with weeks of exposure to high humidity. another thing is the buds on this particular plant are very dense - I need to improve air circulation.

plants have become very top heavy and required some staking. branches are sagging quite a bit.

I started some seeds a few weeks back and plan on putting them into flower within a week since I will have space available in the tent.

8th week of pistil production - almost to the end.

Good for you bud!

OK, lets get back to basics...

pH?
temps?
humidity? (too high since you have mold)

Are you feeding them every time or food/water/food type deal? what's your formula now? RO or tap? Any additives?

2) Mold.
Don't try to save it, dump it.

pH = 5.8 - 5.85

Temps = 80F during lights on, 70F during lights off

Humidity = 45% (currently) 55%+ for a period of about 3 weeks

I add nutrients every watering. I switched nutes about 2 weeks ago from PBP to GH 3 part. now i'm using H3AD's lucas formula for coco. I've had issues with PBP but really like what the lucas formula has done for my younger plants.

mold had just set in when I removed the affected bud. can I chop it up and use it for making oil?

I used liquid karma 7ml/gal, calmag 3ml/gal, and hydroplex 2ml/gal

I mean, i'm not all that surprised. I was running a really high EC when I began flowering under these LEDs. I tried adjusting, but it was after things were already off track. I've had leaf curl and tip burn for most the grow. I think the new nutrient regiment will match my plants needs under the LEDs much better.

humidity was out of my control, I didn't anticipate this summer being so wet. I've invested in a good dehumidifier and this shouldn't be an issue again.

If you're adding CO2 you can raise the daytime temp to 84 and they'll eat/drink more too. Higher temps under LED might help yield.

If you're not using the calmag now, try adding it at 2-3ml/gal to see if those copper spots on the plant on the right gets better.

2) Mold.
Don't try to save it, dump it.

Seriously, it's not worth the health risk, you can grow more.

went ahead and harvested the worst looking plant. i'm expecting something like 3.5oz. we will see. I have pictures of right before harvest; then all fan leaves removed; and finally branches hanging in my closet.
