I think that you are wrong also man. Each to their own though eh.

anything like that, with the very very obvious sidewasy curl on the leaf, marbling through the leaf. i would be very very very very wary. as w.wizard says it may not be tmv, but setting up a quaratine area is not going to hurt while you diagnose the issue is always the best bet, stop the risk of transmition before it gets the chance to fuck everything up. spend some time researching that shit because its a nut cruncher. fucks things up.

Low on Zinc

looks similar to what was happening to me.. I thought it was heat stress, then over watering (aero). You have any clawing of the leaves? slow growth? defects in the leaves, such as small holes, almost like an insect took a bite? Maybe even some yellowing leaves? Problems starting on the lower branches and moving up.. with new growth looking perfectly fine?

If so I think its Nitrogen Toxicity. These were my symptoms and looks similar to mine. Try reducing to 350-425PPM and watch the new growth.

Leaves are not dark green so it cant be nitrogen toxicity, and there are no "nitrogen claw(google it)"

Its quite normal that first set of leaves curl abit.
And just to Shake thing up: purple stems and curled leaves are signs of defiency.

Edit: how is ur PH? A drifting PH caused that. Nothing to worry about tho, the new grow looks fine.
Id suggest you keep an eye on that PH before doing any changes.

Mine do the same thing
