what has helped me now, was switching them all over to coco/pearlite mix, so I can get them nutrients quickly, and I know for certain that its not the soil burning them. and mixing up a foliar feed with micronutes, rhizotonic for the roots, and nitrogen.. I also turned off the two flower panels and put the veg about a foot and a half up from the plants. while the ones in pots are recovering slowly, the two in hydro are going full bore..

It's good to know someone else has had this problem, though its a good problem to have really


weezard, like I said, they had not been fed at all. I considered the soil being too rich, but the coco plants and the hydro girls all showed the same symptoms until I changed the lights. now the hydro plants have shot out new leaves, and the coco ones are slowly recovering. I planted a new seed though a week or so ago, and it's already outgrown the potted ones.. so something has changed for the better I think.
Thanks for the feedback, Douglas1, very helpful and encouraging. The more I think about your comment that this is a good problem, the more I begin to see the light. All it takes, I think, is a simple strategy change. Rather than start the plant up high and lower it as the colas develop, I'm going to start the plant down low and let the colas stretch up into the light. This is testament, tutorial, and cautionary warning to others about the penetrating power of the 240W Blackstar vegger. I've carefully read everything I could find about this light (including a grow journal where a guy pitted a 240W Blackstar vegger against a 500W LED competitor) and by all accounts this light is universally underestimated. It just does not look all that powerful, and the intuitive reaction upon first seeing it in operation is to place it about 18" above the canopy. Judging from its effects on our plants, however, this is much too close (and inefficient and dangerous) for such a deceptively powerful light. I should back up and state that my DWC plant (RIP) was trained into a magnificent 2'x3' SCROG, and my hempy plants were flattened with LST into ~2 sq. ft. SCROG-like bushes. This shaping could definitely affect distances, but my ultimate point is the 240W Blackstar vegger is not a simple light. It has a learning curve, and I suspect when we as a user community finally crack its code, it will prove capable of some amazing production rates. Anyway, at this point, just an educated guess...
