This happened after I went to 1/2 RO and 1/2 tap since at the same time I lowered my Pure Blend Pro to keep PPM down. I'm running in the 1200 - 1300 total range, however will be doing a flush soon and then back things down to keep it in the ~ 1000 neighborhood. I think I may have a lock out happening as I am too high on the Liquid Karma/Sweet and too low on the Pure Blend Pro. I am now watching my PPMs closely when mixing nutes. Water (1/2-1/2) = 175 PPM, then add Karma/Sweet to get to ~ 400-450 PPM, then add PBP Bloom to get up to the approx 1000 target.

I'm kinda perplexed since last cycle (Black Domina / Blueberry) I didn't measure PPMs, just followed Botanicare instructions - which I now know to be too strong - and it kicked butt. I am pretty sure its a lack of base nutes and perhaps lock out that is causing issues. I'd better get it right soon as harvest is probably within the next 4 weeks.

My PH and PPM are not moving too much which is a bit abnormal. Like they are not feeding and excreting too much. What do you think?
