Tips turning into yellow
We started feeding the plants 10 days ago. Some leave tips started to turn yellow, we think is due nutrient burn. We decided to water them without ferts for once, to flush out the excess nutrients. Is it a good approach? Could it be from light stress? (See pic for reference)

What is this deficiency?
Some leaves are burnt but the ph is good, watering is good light and temp good soil seems good and balanced. The humidity is very low can it be because of humidity?

Suspected nitrogen toxicity?
Does anybody have any insight and suggestions for what's going on with plants 2 and 3? I'm treating them for suspected nitrogen toxicity, feeding them calmag-only water. Their runoff EC is still 800-1100 though, which is below influent EC.

Nute burn?
I have one plant that's browning and tips are starting to point up. I'm thinking this is due to ffof soil being too hot for this one the other 2 dont seem to have problems, though another slowed down and is getting a little twisted. Anything I should do besides continuing ph h20?

Hi guys. Considering the several problems of this grow, how I can change my setup for the next grows? Now I'm using Plagron Alga fertilizers and the Promix substrate (no fertilized). Do you suggest to set the lamp in bloom mode (more reds) also during the veg phase? Thanks, M

Yellow tips upper/newer growth
I'm experiencing some yellowing of the tips in the upper/newer growth. Light stress? Nutrient burn? Deficiency? Ph related issue? Should I do a flush with plain PHed water and check the ph of the runoff? I will do some more pictures tonight with the grow light off.
