Those plants are looking awesome... Great job!! The only thing that stood out was the red tips, which could be overfeeding. However I am drawn to a potassium or zinc deficiency too. Otherwise, well done and good luck

Runoffs are significantly below inputs-Do I have a problem?Runoff continues to be a mystery. When watering I continue to get significantly less Ph and PPM (4.8 ph and 109 ppm) than my inputs (6.2 ph and 155 ppm) but the plant looks healthy. I have no idea what is going on or if its even a problem. Should I be worried and what can I do?

Grey leaf tips Booth plants are showing some kinds of burn and I am not sure if it is nutrient burn or light burn or if there is something missing. Looks a bit like MG deficite but shouldn't the plant take that from the soil in that state and age?

Strange discoloration The plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Nitrogen Toxicity?Not sure if this is nitrogen toxicity or normal leaf color. Crinkling was caused by too much light and the fan. Got better in 24h after adjusting grow light and fan. Plants are starting week 2 of veg, Hulkberry Auto. Medium is light mix soil.

Ph value is decreasing despite BioBizzUp I don´t get it I´m trying to increase the Ph value but it is permanently falling again to a value of 4,2. Any idea what could be the reason why my Ph adjustments (BioUp) are not taking effect in the soil. Additional question for SD: What to do with the brown leafes? Remove them?
