I’m growing for the first time DWC ( this is my 2nd grow) and I run into some problems already.
I m growing from seed Super Lemon Haze (Greenhouse Company) in DWC and I’m on week 7 (day 46) from when I pop the seed in to the rockwool.
I use Low’s 5 gallons bucket as my reservoir.
I feed the plants Current Culture nutrients at : Coco Cal 2 ml/g
Veg A 2.5 ml/g
Veg B 2.5 ml/g
Silica Blast 2ml/g
UC Roots 2ml/g
Rapid Start 1m/g
Total PPM between 600-650
My PPM’s are dropping from 600 to 500 and PH drift from 5.8 to 6.2 in less then 12 hours so I have to add back nutrients morning and night to bring it back to 600 PPM.
Recently I got into some problems, I got brown necrotic spots and wholes into the older leafs.
I will attach some pics
I will appreciate any help
