I'll back off the nutes a little, it's weird cause it's only a few stems and mostly old, lower growth. This piece was by far the worst and I was worried that was a pollen sac but it was the start of a bud but only partially opened. I watered last night with 1.5 gallons of distilled water with cal-mag, they are in 3gallon pots I flushed them with 6 gallons last Wednesday and fed them nutes once, and the ppm's were nowhere near what Fox farm suggested cause I know what they suggest are max levels so I will see what they look like in a couple hours when the lights come on.
My pH meter reads 6.5 in soil and stays at 6.5 it goes in half increments at sits at 7 for about 10 seconds before going to 6.5 I tested some soil in a pH solution and it also verified around 6.5 range. But I did notice the buds increased in size a little overnight so when I feed again I'll do half strength.
