You do not have a diary so we are guessing based on one photo. It could be a magnesium deficiency.

Yellowing leaves, some twisting, early in veg?
Could anyone help me diagnose this plant. Idk if it’s nitro defic., heat stress, or overwatering or all 3. Temps during the day have been getting up around 86-88 daytime and only down to maybe 74 at night in the tent. I try to let the top of the soil dry out when watering as well

Droopy leaves, weird spots.
Does anyone know what's wrong with that bottom left plant? Those spots appeared pretty soon after I cleaned those filters. I'm thinking that it's a stress caused by that cleanse, no chemicals or such were used, but some roots were torn in the process. Deficiency? Disease?

deficiency symptoms
I'm a beginner and some plants are getting fallen leaves. They are being watered with the amount of approximately 10% of the volume of the pot and an average pH of 6.5. Runtz has Mag deficiency symptoms after I fertilized, is she also lacking N deficiency?

Leaves looking a bit discoloured and wilting slightly, what could be causing it?
Leaves are drooping a bit and slightly discoloured, especially when comparing it to the other plant. Also, a couple seem to be growing at a much slower rate, is this anything to worry about or will they catch up? TIA
