I have an indoor grow going. I have been cutting clones from 3 mother plants, and 6 weeks or so in every time I start having growth problems both in the vegitive stage and then about 4 to 5 weeks into the flower stage. I have rulled out bugs and ph but can not figure out what is the cause. Here are 3 pics of what I am working with.

Clones usually look beat up for awhile. Damaged leaves won’t recover. The lime green colors is rapid new growth. That’s a good. Welcome to the community!
