In week 3 of flower my hairs started turning brown...then in week 5 my leaves started getting spots on the leaves on top of canopy and stated working down a little now..the leaves tips are also pointed down..the pictures are from week 6 of flower . My environment is perfect..temps and rh are in the perfect range co2 is 1600-1400ppm..im thinking I Fed too many nutes. I feed cal-mag at full strength with every feeding ..I don't feed to runoff so I can't check my soil ppm or ph. Can anyone tell me from the pics what they think it might be..thank you
I'm using spider farmer 4000 and iv lowered the light to 20 inches and 1000ppfd...im losing my nutes to 3/4 strength and ph water to 6.2...what else would u suggest I do next?
