Sick Plants Curled leaves Why?

These plants have been sick since early veg. Couldnt figure it out then but half the garden went to trash and these are the ones that made it. I really dont know how to explain ill let the pictures tell the story. These are san fernando og. Used same nutes water and soil as my other garden and other garden is nothing like this one. Flower pics are end of week 5. Any ideas? Thanks in advance.

Well you have a bunch of stuff going on, watering, feeding, air exc... but ill let others help you out.... im done

Ya i know at this point im not trying to fix it i know its all out of wack. Im just trying to prevent it from happening again.

Well start from the ground up....

Well, you says this has been ongoing, so it would help to know how this progressed. Did necrosis start on the leaves and progress to the stems? Have you seen insects of any kind?

If I had to guess, it is probably root rot.

The first thing that happen was on the stems like in the picture seemed like it was just decaying. Half the plants tipped over even with support. No i had no insects . Heres a pic of the other garden which has been going through exact same process with everything thesame except the room

Okay, well deficiencies typically show first on leaves. The stems dying off so quickly indicates something going on with the roots. This is easy to check since your in grow bags. Cut a hole at the bottom and have a peek at the roots (tape it shut when you're done). If they aren't healthy and white, it's probably root rot
