Red Hot Cookies Sweet Seeds

Grow is going on nicely. Red hot cookies pistils started to turn orange a bit early. Did not experience this before I think. I hope it was not some kind of potassium deficiency. I was a bit late to raise ec. It was around 1.8 in week 5. I was hesitant to rasie it more because run offs ec was consistently getting higher than feed. From 1.8 to around 2.2. I will leave it at 2.0 for a couple of days and see. Than probably flush to lower it a bit down, and lower it further for putting on mass period and last weeks.
