Changed from CFL 250w to HPS 600w, they are still at veg stage (18/6).
Accidentally poured about a total of 0.3 liters of ICE cold water with a ph level of 8.5 + on the plants. (To lazy to pour the humidity bowl water in the sink so I poured it on the plants).
Accidentally poured about a total 0.3 liters of normal tap water with a ph level of 8.5 + on the plants. (To lazy to pour the humidity bowl water in the sink so I poured it on the plants).
Waterd them regularly with a ph level of 6.0-6.5. ( Today i try to give them a little higher (6.5-7.0).
