With hydro the bigget question is what is the ppm and ph.
If your trying to hydro with out them your driving a car wht out a steering wheel.
Ph of 5.6 and a ppm of 1000-1200 over background Ph and ppm
That is the starting point, when the plant looks good.
Looks like your over ppm , but that is a big guess with out the actual numbers.
Than you can add temp. and rh and airflow and co2 , if used.
Small hint people buy pot ferts to grow pot, cause it works.
Its the cheapest thing on the growing cost. l
