Looks like you are over feeding them I'm going off when I did this plant if you read my bio on it there not big drinkers and they don't like nutes I would flush and half dose feed them on your next feed after flush
After you flush 1 to 2 days all her leaves will perk back up also if you go wrong on this plant it will affect final yield out of 4 plants i through one one wouldn't grow any more and I was left with 2 they were nice pal
