Just starting using Co2 out of a tank..Set my regulator at 1/.75....Formula for the room calls for .2 but i alot the rest for leakage...In the 3rd wk of flowering and i'm seeing alot more yellowing of the middle & lower leaves than usual....Running 2000watts, Temps 85/90, 56wtts/sqft, 1100ppm's before subtracting tap water ppm which is around 600......PH 6.8/6.7....I don't usually drop my PH to 6.3/6.5 till week 5.....What i want to know is how much should i increase my food too.....Like to cure the yellowing now instead of 2 or 3 waterings...Got AK, Arjan Haze, White Russian, Bubble Gum, & Pineapple in soil. First time using these strains except pineapple & not sure what they'll take without too much burn......
