These brown spots started happening less than 24 hrs after switching to flower nutes, also I for the first time this whole grow sprayed Potassium Bicarbonate mixed with water for the first time less than 24 hrs ago . So those are the 2 things that could have caused this problem.
the ph rose a lot in those few hours, like .5-.7 and the EC went down by .1. Which makes me think they are taking nutrients but that mixture spray I used maybe burned the leaves. I sprayed it pretty heavy and maybe my mixture was too strong? The Ppm’s are way under the recommendation from the nute company which makes me this it wasn’t nutrient burn. Also I upped the coco cal and on another forum I was told that wasn’t the best to do since I’m running tap water I don’t need cococal.
