Yes, I wondered that too and just as likely it's a build up of nutes. My run off at one time was north of 1400 but under 950 going in.
I also think it's got something to do with my media. I think I'll try a run with coco.
Btw, my experiment with the 1/2 tsp Epsom to 16 oz water foliage spray was a fail. My plants drooped for about day then started growing a little a day after but there has been no change to the variegation in my leaves.
My plants still grow and bloom and chop and smoke just fine and I have a satisfactory amount of harvest for me.
I just know something is not optimal because my leaves are not solid green run after run.
I've been running like this for a few years and haven't been able to find all the problems. There was more than one but the thing I haven't adjust is the media.
At least I know 4-5 grams per gallon of Maxigrow or Maxibloom seem to be the sweet spot. If I feed those strengths at PH 6 and still have problems it's not food.
