Leafs falling down

200W with a dimmer or are you blasting full power? 60W should be just enough for this space (adjust distance 30-80 cm)

too much light... possibly poor watering habits. is that 4sq ft? 50w of LED per sq ft is too much unless it's a really, really shitty LED light. Like one of those older models with big ol honking 5w diodes? Those were barely more efficient than HID lighting. if that is the case, fix the light intensity first... may fix the pale leaves on its own. Definitely a contributing factor, either way.

When seeing this, I wanna jump straight at the leaf color and say nitrogen deficiency, especially as the yellowing seems to travel upwards, but that is not the whole story. Your ladies have extensive cupping / taco-ing and leafe edges that look like snake fangs. They are seriously unhappy with an another, likely environmental cause you are exposing them to. The way the yellowing on the youngest top growth dies out speaks for massive and immediate chlorophyll expension. It is trying to grow the leaf so hard, the rest of the plant can't keep up feeding it. I think this really suggests that your plants are severely light-stressed on top of a nitrogen deficiency.

Feeding and watering incorrectly.

When I let my plants dry out they will droop like that so watering issue was my first thought. But like others say lift those containers to judge if they are over or under watered. I would also clean up the brown and dead leaves and get some air flow with a small fan.

Plants turning pale green and yellowing, particularly from the bottom to the top. Looks droopy and unhappy. Nitrogen deficiency + a watering problem like overwatering or not enough water, depending on the weight of the pot if it is heavy full of water or not heavy meaning there’s a lack of water. Giving some fertilizer and lifting your pots will help to fix your problem

They look very hungry and possibly under watered. They may be relative to eachother

hi...... da hast du wohl etwas zu viel gedüngt......... würde sie erst 1-2 mal mit ph-angepasstem Wasser giessen und sehen wie weit sie sich erholen....... wenn sie wieder fit sind, wieder langsam anfangen zu düngen........ Viel Glück

Hi what are you feeding them? Whatever it is it's too much.
