I just switched my plants to flowering and I think I may have overfertilized. I am growing hydroponically (drip/dwc) in a bloombox. The ppm was about 1100 with a ph of 5.7. Did I burn them or is this some kind of disease??
I am using the nutrients that came with my bloombox. Advanced Nutrients Sensi Grow/Bloom A&B, Voodoo Juice, and Big Bud. I just switched from the SensiGrow to the SensiBloom this weekend.
Looks like slight nute burn. I was using a ppm meter that was not calabrated and burned
some leaves before. The meter read 1200 ppm and leaves started to burn in hydro.
I took it down to 700 and everything was fine from then on.
