looks like it might be a mag deficiency?
Mg can get locked-up by too much Ca, Cl, or ammonium nitrogen. but don't overdo Mg or you'll lock up other nutrients.
if your nutes are designed for R/O water, or any of them are high in calcium, than the 5ml per gallon is probably too much... To me it looks and sounds like the cal. is locking out the mag...
this is when having cal. and mag. broke down into in 2 different bottles is nice, because cal/mag products also have iron, sulfur, and nitrogen, and sometimes you just want the mag or you just want the calcium.
keep your ph low! and i personally would lower my EC if i were you... it seems like 3.0 would be a better EC for like week 5, imo.
and im guessing you have some other micro nutrient getting locked out as well because your old growth is almost too dark and your new growth is kinda pale... this is usually a micro lock out of some sort. or the tops are just getting sun bleached.
idk, i could be wrong.
