Just curious about your ph. I am not a soil person so forgive me for my ignorance . lol Have you always ph your feed at 5.5? I am in dwc and I do 6.0 to 6.3 it's whole life span. I tried @ 5.5 a couple of times but my grows did not like it. I would not change a thing cause they look happy. Like I said just a curious note taking question haha.
