Water more....perform a heavy flush of the substrate to bring the PPM down. Only way to help your high levels. Good luck and happy growing

Friends, help me understand what the problem of the plant is!!
I can not understand that with plants different tips come most people think that the problem is nitrogen! Others say it's zinc or cal-mag! I can't decide how to properly help the plant! I also thought maybe it's too much blowing inside the box!?

Coco and Worm Castings - Does Total Dissolved Solids Matter?
Does total disolved solids (TDS) matter when growing in coco, worm castings, and organic dry ammendments? Am I at risk of a build up of salts? I have seen 2700 ppm in my current grow, but are these simply not salts and therefore OK? Plants look good happy. TY

Organic dried fertilizer and supplements?
I’m trying to go 90%-100% organic with dry amendments. I’m also possibly trying to use some bottle nutrients for supplements as well things like Terpinator I would like to use. So my question is; what dry amendments and supplements have YOU guys used and prefer in top dressings.

Sick leaves, good buds
Some leaves look sick. (Last photos at 8 weeks) Is this an overdose? Do I need to fix this? From fertilizers, I apply only ripen. I plan to give it 2-3 times and then flush and harvest. I know that ripen helps to end life and makes the leaves turn yellow, but not so!
