Yo! Good people of rollitup. I have lurked and learned so much from y'all, and I wouldnt be wasting any readers' time with my problems unless I was as as stumped as I am right now.
My girls:
2 AK47 clones, from pro greenhouse stock.
1 - the problem gal - is in NFT, under a 250w hps while vegging.
Temps - 65-75F, 24/7.
Nutes - AN Sensi grow A+B (also keeps pH around 5.8-6.1, 24/7) mixed in RO water. EC is running at a steady 1.1 - 1.2. Haven't seen any nute burn.
I have tried a few foliar feeds with a 0.5ec mix, to see fi ican get any deicienccies straight to those leaves, but it hasn't made any difference.
The lamp is in a cooltube; air extraction and intake are fine. The tube is around 8-10" from the tips of the plant.
She gets 5ml/10l of H202 every day too.
(2 - her twin sister - is in bog standard compost. She was my clone mother, but I stuck her under the scrog screen a few days ago because she's looking fine, and because I will be switching strains next grow anyway.)
Anyway - problem gal: first, her leaf edges curl up, usually on older leaves. Then the older leaves develop rusty spots, then they dry out, then they die. New growth, while slower than I would expect to appear, is nice and green. She hasn't put out many roots, I don't think, although her roots are growing ever day. Some pics attached. I have thought and thought about this - does anyone have any ideas?
Basically - this doesn't tally, as far as I can tell, with any of the sick plant diagnoses on the very helpful threads elsewhere in this forum (if it did i wouldn't be troubling you folks).
Here are some pics.
I promise to beam waves of good karma to any responders from my very own frontal lobes.
Peace.
