AsNoriuanswered grow question 2 years ago nice girl , just overfed
Slow down with feed
do brakes each time, feed, plain watering, feed, plain watering
you on the verge of nitrogen toxicity , loads of different problems could start from that ...
10 years ago old hippy would say you on the max feed, they called it nail polish or manicure or something ;) first sign for me, that i overdid something
dark leaves are not so photo efficient.
Happy Growing !!!
