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

I hear what you are saying but it was getting bad. That plant looked horrible about a week ago untill I pruned the plants. I wouldn't have worried but more and more leaves just kept getting more and more yellow and dry. There def was something going on that I had to fix or my plant would have lost all the top canopy leaves and been unhealthy. I'm pretty sure I took care of it now but I have to give it a few more days to know for sure. I think the RH was too low and I wasn't watering the air pots with enough water with all the hot air from my lights blowing straight back down onto my canopy was really stressing out and drying out the top leaves

Do you want to maintain that vapor pressure deficit throughout flower or what? I could see alot of issue's with mold and mildew with big buds sitting in 70% humidity

20181111_114319.jpg 20181111_114414.jpg so the temps and humidity is not the problem! They have just got worse as the cupping is have moved across the entirety on the top canopy and some slight yellowing and as you can see tips of that leaf have turned purple???? like wtf... I need help

Just not really much of an issue, a little yellowing but nothing major, I feel like the purple lights make things look worse than they really are

cupping is spreading throughout the entire top canopy of all 4 plants now and leaf tips are still yellowing and some leaf tips are purple now. I did a flush and that didn't correct the issue, I turned my lights down and lowered temps and increased humidity and that didn't stop the problem. I am feeding with GH FLORA TRIO so the soil is getting nutrients so I don't know what the hell is going on

Probably a ph issue then, what is your ph? Running a hydro style medium right?

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

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

Sounds like that could be an issue by itself, start with actual soil, add 1/3 of the amount of soil of the compost, about the same amount of peat and perlite combined, maybe a handful of garden lyme, little bit of bone meal, some castings, mix it all up real good and see if that helps any

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

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 as I transplanted into 15 gallon totes bammm yellowing gone

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 size I had to.bust it all loose to use the new soil in the grow bag. I can only do tho by rinsing it away and I don't have a hose and it's cold out anyway so I had to do it in the tub and it made a HUGEEEE MESSS!!!!!. I still have 3 more to do . well hopefully that 1 plant starts showing signs of recovery atleast

Sucks man, but mistakes is how we learn, hope you can salvage, but if not it wouldnt hurt to start some new seed since you already got the soil mixins
