@dudegrowsweed Hey dude - Almost out of the swamp: @Mr_Positivo was bang on, it was due to light stress. Was running under a 600W LED hanging at 24 inches above the plants. No bueno.
My leaves were clawing downward while rising upward, also known as "praying for magnesium". At first I thought it was either a nitrogen toxicity (clawing downward) or a nascent magnesium deficiency (leaves shooting up). I also thought the cause not to be the light but the strong tea and nutrient solution I fed the plant back to back, the latter's pH being way too high, which I thought caused a nutrient lockout.
Then things kinda got worse: I downgraded from 600W LED, to 450W LED, to 300W LED. The 450W stayed for a few days but overheated the grow tent, drying the plant, which made me overwater, hence the wilting in the last few days. I think I got a combo of light stress and magnesium deficiency to start it all. I don't add CaMg+ each time to my reverse osmosis water and the plant may have lacked a bit.
Now that the plant runs under 300W LEDs running at less than 25% intensity, hanging at 24 inches above, and that I've let her dry out, while feeding her CaMg+ & Epsom Salts through foliar sprays for a few days, she's recovering and clawing is improving. I got a set of full spectrum 50W & 100W LEDs to experiment a bit, especially as the plant keeps growing upward and the space between the top of the canopy and the light reduces. Might have to just finish her under 50W to avoid burning the tops.
Hope this helps for next time. Bummer you had to kill yours. Experience is the nickname we give to the mistakes we learned from ;-)
