Thank you. Do those spots seem like PH was the culprit? I'm havin' the toughest time with this Milwaukee meter. I tested the water at noon, 5.8. Five hours later, 6.3 same room temp., humidity, etc. I recalibrated the meter, it was off .5. Added nutes, adjusted the ph to 5.8, moved the lights up to 12".
I'm including some more pics of the spots. Would u mind looking at the root pics to see if everything looks in order as well?
Stink, I hope there is a special place in heaven for you and everyone who pitches in. Nobody has to respond and someone always does. I will certainly roll it forward when I have the chance. Many thanks,
