Hi all...
I've been blindly following the GH Drain to Waste feed chart for my grow. I'm growing in 3 gallon with 1/4 SS#4 and 1/2 ProMix and 1/4 perlite.
Anyway, I've been feeding about once a week at about recommended PPM from chart...then water the rest of the week (usually 2-3 days later) then it's time to feed again by time it's drying.
I noticed some burning on leaves and yellowing over the last week or so. I thought it was probably a combo of the lack of nitrogen and liquid KoolBloom.
But today I decided to check and I watered in at 300ppm and my runoff was 1800ppm!!
Should I do a quick flush this late in flower (about 2-3 weeks left) or just drop feeding schedule for a week or so to try reduce soil PPM naturally by using straight water and letting it use some of the nutes in the soil?
Thanks
Edited to add:. Also...the pH going in with the water was 5.9 and the pH coming out was 5.75
