Ok so I water my coco with 1800ppm at the moment because I have a slight deficiency and I recently killed a bunch of gnat larvae and adults that were stealing the nutrients.
I have checked runoff ppm and it is at 2400ppm that seems high to me.
Ph is at 5.87 so no issue there don’t think it’s lockout. is It is in first day of week 6 flower so don’t wanna shock it to much.
The plant is in alright shape considering it’s week 6 and had gnats
so should I flush my plants with water to lower ppm or is 2400ppm ok for runoff in coco at 5.8PH
Any help would be appreciated
