Agreed, more details! Although from that it could be calmg def or k? There's a guide online that gives you all the stages of def in plants and tells yoi how to reverse it.

Well those look like they're over watered and have too much nitrogen but your discoloration could still be a rust fungus

I agree they do look over watered , this could all be a sign of root stress , from low oxygen environment in the roots , allow longer times between irrigation

That leaf looks like the plant is taking it back.. It will dry up and fall off. If it is a lot of leafs then worry otherwise that ia normal..

The guys warned you on the watering. Your roots need air man

Ok I think my res is too full. Should 50% of the roots be exposed? Also just figured out I did not add any cal.mag. and I use r.o water. I am on 10 min off 1.5 min on. Should I go 15 off 2 on?

As far along as you are I wouldn't worry too much or at all. But for the future I definitely think you should max fill your tray to get as much root coverage as possible just don't do it 6 times a day.I think every 8 hours or 3 times a day is the right amount but I do know people who go every 6 hours

How about cal mag. I did not realize that I needed to add it to my res. Can I add it next water change with no harm?
