Yellowing seedling-bubble cheese

I am growing 2 plants both feminized. Bubble Cheese and Amensia Haze. I started with 2 26 watt cfl 5000k spec for each plant, about 4 days in i exchanged 1 26watt with a 42watt 2700k spec for each plant. all on 24hr schedule. Day 7 I noticed a a little bit of yellowing on both so i cut it down to 1 26watt for each plant. The temp stays around 75-80 and humdity around 30-40%.

its now day 8 and The haze looks better after cut down to 1 light. but the bubble cheese continues to yellow, its starting to curl a little, and lighten in color, also slower growth.

as far as watering goes i dont think im over or under watering because I have a moisture meter. The ph is good its around 6.5-7.

Please help!?

lol im having the same problem with my bigger plant. if stem is purple / leaf stems are red its most likely a nitrogen defiency.

i posted this same thread in a different forum and this what i was told....let the soil dry out finger deep before she gets any more water.i had similar symptoms with my plants and that was the problem.you might want to try switching to 18/6 light schedule.youd be amazed at the amount of growth during the dark period.good luck brother.

the stems are great
do you mist your plants?
cuz i do mine when the lights are on (well theyre always on) and the mist on the new plants will burn it cuz it magnifys the light

yeh dont mist with lights on. i never mist my plants. i never really foliar feed. maybe one time throughout the entire grow. i prefer to feed through the soil. i think ive got a N def. on mine. red leaf stems/ purple main stock. and now they starting the yellowing of oldest leafs. i read up and all points to the plant needs more N so im giving it a small dose tomorrow and see what happens.

go to 18/6 light, your girls want to go to sleep, but thats proly not the reason your seedling all fukd, drying the soil finger deep is great, if your plant roots has consumed the whole pot, if not go by weight
