Just by the leafs looks like a magnesium deficiency. But the whole plant must be taken into account...

That is a magnesium deficiency, i see the tip of this leave pointing down, which suggests watering issue. But... Hard to tell w/o seeing whole plant and situation. So could be too much water, could be not feeding calmag while growing under LED, could be PH that is too high or low, preventing this. Let soil dry, do a foliar spray with some calmag.

I need help troubleshooting weak plants! I think the clover might be the culprit but what do I do?Can anyone tell me what’s going on with these plants and what I can do? This is my first grow. I can already tell the seeds are growing slow because other seeds I planted in smaller pots are growing much faster. Any advice would be greatly appreciated!

Yellow tips?First timer here. What might be causing the small, yellow tips? The leaves sometimes look slightly pale but damn if they don’t look super healthy overall! I’m using minimal nutes thus far. Any insight? Thank you, thank you.

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
