Disease or something else?

[Dr.NO]

A friend of mine is having issues with his vegging plants at the moment.

Feeding multiple times a day flora flex v1 and v2 in coco ec was 1400 but has been lowered, temp mid to high 70s, humidity in the 60s, nute mixing buckets cleaned with iso every 2-3 days and new nute mixed.

Seeming rot occurring in lower leaves and new growth on all plants.

Im doing this from mobile so I’m not getting too detailed and hope the pics work. Any help is much appreciated. Thank you.

They're struggling. It's not disease. Consider it a Crime scene, and this is the result of the cumulative effects of anything you can think of that was done wrong. We can only go off of the information you give us.

Overfertilization is definitely a stress inducer, and is probably the main problem. Having corrected that, things should bounce back. Just remember, during the rebound phase, less is more, don't push them to do it. Reduce all inputs and allow the plants to recover. Your humidity may be too high during the dark phase causing condensation to build up on leaves. This becomes problematic if the air is not actively moving.

Also, your EC meter might be set to give your reading in ppm. You can go into the modes and set it to read in mS if it is.

Root rot/over watered/fed.

She(he?) needs oxygen to the roots, apply less water and use a more airy soil medium

The lower the pH is, the more hydrogen there will be to exchange with the other nutrients. Lower pH = more H = more nutrient exchange. Higher pH = less H = less nutrient exchange. If you buffer your water and raise the pH it should help.

The higher the pH is the more negatively charged hydroxyl ions there will be to block nutrient exchange. If you use a complete fertilizer you can slow down or increase the exchange of nutrients with pH, regardless of ppm or EC. Watch your pH closely for best results.....
