Puzzlement. Pink Kush Auto, grown in DWC ... why are those leaves curling?! If this were soil, I'd say too much nitrogen ...

Same concept here too much nitrogen. I just had this in two of my autos. I just only added water till I do a solution change. They grew super fast after that.

Last compost tea was probably a bit too strong, causing clawing and droopiness these last few days. The following feeding was RO water only. I'm wondering whether there is some kind of nutrient lockout or N tox/def going on at the moment. Growth upward hasn't slowed down though.

Yellowing, wilting, stunted growth
Can anyone please help me identify whats wrong with them. I've done a flush, adjusted the lights, reduced the nutrient strength, I've pretty much done everything and still stunted growth and they are still looking weak and frail. I'm lost and I don't even know what's wrong.

Dark shiny leaves, Clawing towards the ends. Is this a sign of N toxicity?
Hello, I am a first time grower. I have plants going in Fox Farm Happy Frog soil with 4-4-4 Gaia greens dry amendments. I believe the soil is too “hot” and wanted to get your guys thoughts if you agree and if so, what to do. I water every 2-3 days using the knuckle test. Thanks!

Crumpled new growth?
I've noticed that there are new leaves towards the base of the plant that are growing strangely. Could this be from low humidity? I've been having a hard time keeping it up. I also noticed that some of the leaves are clawing down (see week pics). Perhaps related? Haven't fed yet!

They are on the older leaves and they keep getting that faded yellowing starting from the tips. The pH of the run off is 6.43 and they havent been fed a round of nutrients in a week! I thought it was a cal/mag def but they haven't bounced back after a dose. Help please!

Droopy leafs getting worse. What am I missing?
The leafs on these Purple Lemonade autos are getting progressively dry and droopy. not sure what's going on. I switched to watering the plants directly from the saucer as I'm really bad at determining how much they need. Humidity too low? What am I missing?

Over Fed, Watered or Lights to close?
Either I over watered, over fed, or the lights were too close. I already raised the lights to be 24" again, the plant grew fast and was only 16" away. Should I wait to feed again or continue as normal? The temp is 73-75 lights on, lights off it was getting down to 63.

Overwatered?
I just watered my plant and after hour or so the leaves are pretty droopy (only the ones near the top). I never noticed it happen before, so I'm a bit concerned abt this. I water abt 1L/3days.

Yellowing dry leaves, late flower.
About 2 weeks from harvest time, the yellowing leaves which I put down to an early fade have become dry, brittle, curly and splotchy. Should I worry this late? Is it potassium defeciency, lockout? Should I begin flush? Add molasses?
