You have a ph in your substrate is off. You are in lock out on several nutritional needs. Run enough of correct ph water through soil till run off reads in range then replenish nutrition.

Yellowing of top fan leaves
What is causing yellowing of the top fan leaves? Started to happen to a plant that I broke by accident during LST. However around the same time I upped to 2ml/l and moved the light a little closer. My ph has also been high (fine now). No idea which one could be the culprit

Grey leaf tips
Booth plants are showing some kinds of burn and I am not sure if it is nutrient burn or light burn or if there is something missing. Looks a bit like MG deficite but shouldn't the plant take that from the soil in that state and age?

Yellowing leave tips and clawing down, do I need to start giving more nutrients?
Hello all, I'm experiencing some yellowing leave tips on newer growth, it is paired with some light clawing (downside) on the newest leaves (only on the green gelato). I have used very little nutrients so far and have fertigated only once in fear of giving too much.
