Yeah i see u use ca/mg. But i also see that ur ppm on run off is thru the roof. And uve been sayin that u thought they were growin slow. Maybe u have a lil nute lock out causing ur pom to go up on runoff and in turn not letting the plant intake the ca/mg but im a soil man. So im jus assuming. Id run sum straight ro or phed water for a day or two kinda like a flush. Or wait till a hydro guy churps in. But good luck man hope everything works out for ya. Ill b checkin in this grow i love sour og. Stay green
