wrinkles leaves kind of bumpy only a few.kinda spotty ...blackish grey but ..did just have an overwatering prob...im in a 8gl pot....with fox farm ocean siol...usin fox farm tri kit...only big bloom ,and grow big for now...still in veg....ph...6.7 light 400wt mh....18/6...18inhs away from plant ...plant is 8wks old...any ideas...heres a pic

come on any ideas....y no feed back

look for bugs on the underside of the leaf, you might need a magnifing glass. since the girls are still in the vegging stage i would spray them down with some sevin, it comes in a red bottle and you can find it in the garden section at all the big box stores.

my guess would be bugs aswell

i looked....no bugs...in soil or leaves ...i have a 100x zoom scope hydro farm....there bouncing back now....think they needed food....
