What is this.

IDeal to what is the cause of this. White widow and plants about month old. Also have second picture of younger white wdiow. IT is about 2 weeks into veg. I sort of know what is wrong with second plant but not with first. Thanks for any help

Um... a VERY healthy plant with some natural aging of the lowest leaf which is no longer receiving much light since the canopy is pretty solid above it. Nice work!

THE last two pics are of different plant. U see the first two that the leaves are twisting. The second two is plant that is 2 weeks old in veg. Yellowing is is progressing.

What's your temperature situation? There's some slight heat stress going on in the first 2 pics. Not the twisting, the slightly curled-up edges.

Tehy arent curled. THEy are twisted. Just look slike they are curled up.
