5 Queens - Hesi vs BioBizz Experiment

Growth in general continues well plus theres now an increasingly sweet smell. Sadly the leavetips on both BioBizz fed plants continue to get worse. The get yellow, then brown, curl up and get crispy.😟 Since some lower foliage on those plants is getting a little yellow and reducing nutes did not seem to help them I am ramping the BioBizz up again. It's not like they are dying, they still develop nice frosty buds, but their sisters on Hesi just look that much healthier. Funnily the Purple Queen Mini (the actually purple one) in the small pot that gets a little bit of both nutrients and mostly just plain water is doing good as well. But she also got some organic fertilizer pellets in the soil. Those are rich in potassium so she always tended to have slightly yellow leavetips, but thats quite alright. She is doing very well. For now I am guessing towards some nutrientlockout because of pH, because there are too many growers I know and trust, who are doing fine with BioBizz. Will have to find a way to check up on the pH of what I am feeding them...
