What does my plant need? I watered two days ago to...

The problem was not enough nitrogen during the veg period and she's stripped her reserves already, make sure your pH is correct and keep feeding as per schedule, the buds are coming along but the leaves are dieing off.. Good luck pal

it needs more leaves... looks like you stripped it down and now it has all the resources in the medium but no manufacturing in the leaves to use it. and the leaves that are left over are looking burnt and crispy. A lot of things went wrong and their is no easly solution. keep it going till harvest and make notes for next run. Have a plan and stick to it.

curling inward and burned tips = overfeeding and your plant looks like that. so no nutries for her. just water, maybe with vitamins/enzyms but no NPK.... you can flush out your soil with some liters running trow the pot, but then you need a few days for the dryback or a very warm growroom/light to dry faster. the burned leaves you can remove - the will fall of anyway. i think you lose a week or two on all of this before it starts to go its used healthy way. on the other side you can also just ignore the overfeed leaves, leave them until they fall of alone, just flush the pot once and go your nutri way after 1-3 times just water until end of plant with lower dose like 50%. (or feed her near to toxic-death in hope that the buds still grow until they are ready and dont look on the rest of the plant ) ^^ just suggesting some options
