how can it be a def when ive been giving it the perfect balance. My ppm is exacly 1090 right now thats gotta be perfect
As long as your nutes are within the 2-week lifespan, all should be well.
and i was misting so much and my plants were only liker 10 in from the light they def got burnt
Misting is really unnecessary in a properly operating grow room. One usually fights to keep humidity
down. Adding more humidity is counterproductive- and can cause problems, as you accidentally found.
Some folks swear by foliar feeding, but even they would tell you that you must not do it during lights-on.
Al im gonna switch to flower im gonna put in the flowring mix should i go up in ppm or still keep it at about 1000>?
Bump it to 1300-1500ppm @ pH 5.3-5.8.
You have some pruning to do. Remember that your plant will double to triple (if not a bit more) in height by the end of flowering. You should shorten (if not totally remove) the lower branches (bottom 1/4 to 1/3 of the plants) or you're going to have air circ probs caused by crowding.
If you haven't got enough vertical space under your lights to cope with a tripling in height while still maintaining adequate spacing from the lamp, consider cutting the mainstems 1-2 nodes down from the growing tip. This will divide the growth and make things a bit more bushy, but it will hopefully stop them from growing into the lights before the end of flowering.
How high can you hang your light? How far is that distance from the lamp to the tallest plant tip?
