    constant unoscillating wind, heat from lights, resulting in low RH

    I would just cut some clones but they are def going to make it. Far from the point of no return. They are actually still growing very vigorous and green just some of the bigger leaves on the top canopy are cupping and having some coloring but other than that the plants look healthy

    constant unoscillating wind, heat from lights, resulting in low RH

    I got some plain Scott's topsoil )it says it has peat moss in it) and some perlite and I transplanted 1 of the 4 plants and I am going to see how that does. It was a nightmare because I have to wash away the huge dirt/football which is the size of a 7 gallon grow bag. Since I'm not upping pot...

    leaves on top canopy cupping and tips turning yellow/purple

    yes I made this myself. I eyed up using the lime. I am absolutely positive it's not to hot or too much light. I am going to get some regular soil and more perlite and re pot. After all the trouble shooting I have done, this is where I'm at. It has to be the leaf litter compost, it's a soil...

    constant unoscillating wind, heat from lights, resulting in low RH

    Iv been delaying flowering the plants because of this problem. I will never go into flower with a problem. Had to delay my last grow because I had major leaf yellowing from bottom up and couldn't figure out what was going on and come to find out plants were root bound in 5 gallon pots, as soon...

    constant unoscillating wind, heat from lights, resulting in low RH

    Yeah that was my next step. it has to be the issue because everything else is dialed in. I'm going to do that minus the meal and castings as I liquid feed. That's why I mix my own soil so there is minimal nutrients in my medium

    constant unoscillating wind, heat from lights, resulting in low RH

    it is a soil conditioner. it just ground up n composted leaves and shit. says high humus content. it looks and feels like a soil. If not amended with other shit it gets muddy when watered so I amended it with peat moss n perlite

    constant unoscillating wind, heat from lights, resulting in low RH

    I'm waiting for my calibration solution to come in the mail for my Milwaukee mw802 because I haven't calibrated it in like a year and I'm not getting accurate readings so I am not sure what my ph is but NO, I am in soil. about %50 leaf litter compost, %30 peat moss, and %20 perlite

    leaves on top canopy cupping and tips turning yellow/purple

    This problem didn't start untill I transplanted into 7 gallon air pots. I used leaf litter soil conditioner/compost with peat moss and perlite and some garden lime. I feed GH FLORA TRIO every other watering. I did a flush of the pots even though the issue started about a week after transplant...
