Wow well thats awesome news, thank you so much for the advice! I will definitely be posting here more often!The plants have good posture and the lower leaves look brixy....so I say just carry on!
You're doing a great job. I'd max out the Growth Ionic when drenching....like 1-2 oz per gallon of water.
I can't say what those spots are, but they're NOT a root problem, because the signs of that are lacking. Perhaps a clogged sprayer and some very large drops of Brix foliar once upon a time....
