Seems to be pH issue which could be causing lockout, by the way those new leaves look dark I would say P deficient.
Phosphorus (P) deficiency during vegatative growth. Many people mistaken this for a fungus, but look for the damage to occur near the end of leave, and leaves the color dull greyish with a very brittle texture.
Yeah I had a P deficiency and it acted the exact same way. I tried giving it just water and it only got worse. Like dude ^ said, check the ph and give her some P and it should stop in a few days.
Nope. I planted these near the beginning of may, grew under a normal light for 3 weeks then straight outside. They're over 6 ft tall and the 1st plant is too tall for the greenhouse now - I don't know what 2 do???
Your plant just needs to be fed, it's starting to eat the stored food from the leaves and thats why you see your leaves getting lighter because the plant is directing the food to the new budding parts..
