I see that on here all the time with biobizz. That and other organic nutes sometimes just can't keep up with the new leds. Raise the light or use synthetic nutes. gl man. I've never used it myself, maybe an experience biobizz guy will chime in.

BioBizz are organic nutes, but the manner you have to deliver them is not. You need to be checking pH, ppms and runoff ppms at least every other feeding.
BioBizz can still cause issues because of the feeding style. Root zone issues are common to the type of feeding, not just the brand.
How and when do you water and feed?

I water 0.64 gal of water with the biobizz nutes every 3 days. I will check the ph next time I water and keep you guys updated.

PH is around 6 which seems pretty low. biobizz states that its nutrients autocorrect the PH to 6.5. What do you think?

Yes they correct down, not up. They won’t make your water more alkaline, but will make it more acidic. That is what i know. If you have ph at 7, the nutes birig it down to 6.5.
On the biobizz schedule it mentions to use with their soil and nutes 6.2-6.5 ph water. Any lower and the plant will not take the nutrient in corectly and enough, and any higher will take too quickly. Get a ph meter, not the paper kind. Cheers
