i started my plants from seeds under a flourescent t5 light . the plants where doing great nice and green and growing fine . i moved them from that light into a closet with a 400 watt mh light . i have all good ventilation . i have intake from outside in also have ac in there to keep it at 76 in the room . my question is for some reason the leaves are starting to turn yellow on the plants . i can't figure out why . i tryed turning the ac off thinking it was that but they are still turning . soil is fine checked that . any idea why this is . i have a picture but for some reason wont let me upload it

are you feeding them yet? what are you growing them in? what nutrients are you using? Are the that leaves yellowing start from the bottem of the plant the oldest leaves? if so Start feeding them they are nitrogen deficant. If you dont start feeding them now the will slow thier growth to a stop

they may be a little nitrogen deprived,but we did a grow where we were attempting to clone under the MH light to see what would happen,and the leaves beban to turn yellow at the tips,moved some of them back to flouros,and they recovered,the ones left under the light died.So did the seedlings,the light was too intense for them to properly transfer nutes.The ph was 5.6 on the younglings,with an ec of 1.6 controlled.

i dont think its the nuts it has to do with something by putting them in the room can there be something with the light should i switch the light to the sodium and use that . i had this problem before and had to start over now i dont want to get rid of these . last time it seemed when i took them out of the room and put them outside the color cam back tothe leaves and the new leaves where green and stayed green when i put them in the room same thing happened they started to turn yellow .

to me it just seems weird that they are fine when i have them in my sheed outside under the t5 light and then when i bring them in the house they change color . i am thinking it might have something to do with i need to pump more outside air into the closet .

fresh air is crucial in photosynthesis.the plant cant grow or produce oxygen without it.It just uses up all of the co2 in the air,then stops metabolising because theres no oxygen left to assimilate
