Nice grow.., I have had issues with the proximity of the light, so 8-12 inches is the closest I let it get, When they were in veg 2 of 3 got really green and I had all kind of nute issues, so I dropped to plain water (DWC) and feed them every other day adding approx 100 ppm tds GH nutes and calmag. My R/O auto adds Calmg and the light really is signifigant, I think with the 440 less is more, .
Sorry, man. I don't know the hydro lingo. What does R/O auto adds Calmag mean? You have a reverse osmosis machine that automatically adds calmag?
Yeah, the plants were hit pretty hard by something. I can't imagine I precipitated it even given a lack of experience growing this species. It started barely a week in. I am interested in your comment about the light, less is more. Think it can burn? And on that note why do you think at this stage the tops are totally burnt, still some foliage lower down? (I'd like to come away with some piece of knowledge from this struggle)

What i found was i top dressed lime to recover them. What i went on to figure out tho is the soil its self . I was using Sunshine #4 mix and personally i will never use it again. Now iam not a long time grower. However out of all the types of soil i have used. I still think that Pro-Mix Hp still seems the best. Holds a Ph level from start to end. Never had a problem with it....... yet..
