zerobane

@zerobane, Yes it is. this is my 3th grow my last one was the best. 480gr dry of 15 plants. But i have still allot of canna aqua, i want to switch to ghe lucas formula. because i think the leave color is caused by npk shortage. A couple of days ago i added pk13/14 and it looks al little better now. And i already used some calmag every time. My tap water is 390ppm so ik was already looking for a reversed osmosis filter. But nice to see you'r on aero too,

@BertusBabaloeba, yea; aero is finicky... Had good luck with 50ppm RO water then dosing it with calmag+ and AN ph perfect at about 1/2 doses from feed charts. Was looking around to see what others are running for their nutes in aero setups.
