BSF Gorilla Glue Auto

Good start of the first week! GG2 seems more vigorous that GG1. Day 10: GG1 looks droopy... this is the second strain with the same symptoms in the same soil Monkey Light Mix Pro. This time i didn't water that much, but she looks droopy still and behind GG2 in terms of growth. Now im solely blaming this mix. The package says to use it as it (without extra coco nor anything else). I haven't watered this plant for seven days now and the soil is still moist. GG2 looks great in the same custom soil I've used for my Tangie XXL. Watered her with 250cc and 0.5ml/l Power Root and some BAC Funky Fungy. Day 11: GG2 vigorous growth; GG1 growing at a much slower rate and droopy. Day 12: got my PH meters finally. PH were completely off by a lot. Watered a little bit with plain water with PH 6.08 Day 14: watered again with a mix of water, cold coffee and lemon @ PH 6.05. Using a greater amount of water at the risk overwatering but trying to get that PH down. I think they will stress a little but not too much.
