Dos Si Dos #33 - Hydro (1st grow)

Second week of blooming (I guess?). I managed to save some sub-colas that went sh*t during last week (see on the canope, a square of it is gone). Temps are very low those days and I will be able to turn on heating only starting from Monday next week I still have difficulties to maintain PH between 5.5/6.5 without exploding the EC lvl (I stay at 1.7 these days). Everytime I scoop my soup to add fresh water and PH+ to adjust, it stays good for one day and the next day the PH lowers down again 😫Any recommendations would be much appreciated 🙏 Besides that: I’m quite happy with the results so far. As a newbie I think I’m managing the best I can so far :) Keep updated!
