I gotta take pics of the other one but flushed both and ph was 5.8 instead of 6.4 so that's part of the reason they are doin so shitty another is vpd is high.
man these look neut locked and have a serious calcium excess, to me they look as if they need more nitro phosphorous and sulpher. try 1 feed of per ltr nitrozyme at 1ml and mag sulphate at 2ml. also slow down on the Herculean harvest this is suffocating your girls.
