Hello everybody, I have 2x 3week old master kush and 2x 2week old mk; about 10 - 15 days ago they started to show some spots; initially i thought i sprayed the leafs (with water) and the lights might have burned them, now i know this is not the problem, i haven't watered them before lighting the growing room and still they keep having spots; here is a short description of my set up: 1 MH 150W + 5 CFLs (23W, 3 warmlight and 2 coldlight), the 2 larger ones are about 20cm from the MH light, and the smaller have the cfls closer to them at about the same hight from the MH. I used regular pH 6.2 water, no fertilizer, only prefertilized soil (multipurpose); the problem started when the first plant had ~10cm. They're beautiful and growing OK, just that these damn spots keep appearing on the new leafs, PLS if u've got any idea what it could be...please let me know, its my first grow and it all went pretty good so far, and i fear they'll eventually die on me, today i'm buying a ph meter to see if maybe that's what's wrong, pls people any thoughts???
