Hello all, noob here. Noob to rollitup, not to growing so much...but I am having a small problem that caused me to finally join this forum (had been reading it for almost a year now). Ive got a mother plant in soil that was being vegged under a shit ton of fluorescent bulbs. Using earth juice full line of nutrients (plus botanicare silica blast, and superthrive) every other feeding with straight water in between. The plant is approx. 30in high at this point, and is overall pretty healthy looking. During that time, i started to notice some bottom leaves and leaves that generally werent getting enough light starting to go dark green and becoming crispy. The plant was starting to become root-locked in its 1.5 gallon container, and I figured it wasnt getting enough light. So Ive now transplanted (with flush) to 5gal bucket and put her under 600w HPS. The tops are looking fantastic, but it does appear that the problem is staying constant and maybe even spreading slowly. I do pH balance to 6.5. So heres a brief list of symptoms:
Leaf tips become dark green and crispy
Sometimes the tips will curl upwards
On the rare occasion it spreads over a whole leaf, the side edges canoe downwards
Thanks guys! Any help would be greatly appreciated! I was thinking it might be related to the superthrive--I accidentally doubled the dose in my reservoir. Let me know what you think!
