You have to be careful adding the extra p and k,I give a 1ml shot of koolbloom a couple times through the grow only.Once at flower transition and once about 3 or 4weeks flowering for the bulking phase.Replace 1ml of bloom with 1ml of koolbloom or similar p/k booster.But I wouldnt do much more than that,it will contribute to deficiencies and problems...keep her rolling as is,thats my advice.As usual keep an eye on PH and ec.You should slowly raise ec until you start seeing slight tip burn or other issues,when you see that cut down ec .1 or .2 less,try to maintain your ratio.I wont be running lucas next time...it works,but keeping ratios etc is a pain in the ass imo.I see you have slight tip discoloration,thats good and tells me your ec is about on track.g/j
