Why are you mixing the coco in?

I'd flush well (two to three times the pot volume) with 6.8 ph water.

Mix per soil applications, not hydro. Big difference in needs.

If feeding daily, you are building-up the nutrient level to toxic levels and dropping the ph. Likely getting a salt build up as well depending on the nutes.

6.3 to 6.8 ph for peat based soil (and peat based soilless) mixes. :thumbsup:

I'd back off the additives till they are looking better.

I made the mistake of trying to grow multiple strains in the same room with the same formula. It seems that only one of the strains is effected. The effected strain is querkle (purple erkle x space queen). Unfortunatly, I trimmed away all the worst leaves before I took these pictures. Hopefully you can still get a good idea of what's going on. The room is way overcrowed as it is and even Rating: 5
