A few pics of an issue.
Megacrop V1, 80f, 50% RH, HLG LEDs - about 500ppfd, rockwool, Tap water: 50ppm, Feeding started at about 600ppm (incl. tap, 500scale) as that’s what plants got on flora nova bloom prior. Started doing 1gr/L and up to 1.3 gr/L now over the last few days. They were fed 1.4gr/L today.
pH was being set to about 5.7. Test with a meter, to get me close and always double checked with pH drops kit. So it’s been consistent. Now being set at what looks closer to 5.9/6.0, partly because P should be more available(?).
Anyway, the purple petioles and partial stem is one thing, but this leaf drop - not clawing - but drooping or downward curl is progressing, coupled with the oddest thing, the disfigured or twisting leaf fingers - which is also seeming to get worse.
The N/green of the plant looks fine. It doesn’t look burnt. There’s one pic of a leaf where one finger flipped over 180 degrees. 36 hours later, max, and I see a deficiency (splotch) on the same leaf, different finger. Also, a top leaf I plucked now how deep dark copper/purple area(s) on it… phosphorus deficiency?
I thought there was a micronutrient that could cause warped/disfigured leaves in excess/deficient amounts, or pH also. It’s not pH. Plants are at least 2 months old, clones recently taken from top due to height. They took off with growth when megacrop was started, they clearly like it or something about it. Haha.
