Then increase every week after you see good growth by 100 ppm until you reach 800 to 900 ppm. if their autos, stop at 600 to 650 and only give more if you see they really need it..

What deficiency is this ?What is happening to my plant right now ?
I believe it is calcium deficiency also could be Manganese from the pictures. I did not add CalMag during the first weeks.
Usually Calcium deficiency shows after 4 weeks and during flower but not likely in soil.

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?Week 6

Strange discolorationThe 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.Leaves.

Ph value is decreasing despite BioBizzUpI 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.
