well throughout my first grow, I used Supernatural Brand Bloom Terra for the first 3 weeks then switched to Monster Bloom by Grotek, with amazing results. then I switched to some liquid ferts, DNF Bloom for this grow & it gave me P & K deficiencies due to low ph. its supposedly great food but more geared towards hydroponics I guess.
Ive since switched back to the Monster Bloom & everything is fine again!
are you having similar issues???
