Its a good thought Unc .... but i don't think its my problem here . even though the room is cooler than it has been . i still give them time to dry out in veg to build roots . & my feeds are less often cuz of them being a bit cooler . so they may get saturated at feeding .... they have a few days to dry out first before i hit them again . i go by pot weight .m going to bet that the real cause of everyones mag def symptoms is going to have to do with how wet the root zone is or isnt...theres a whole interaction that goes on with sulpher and calcium and water within the medium and inside the plant and all that is related to how the plant is transpiring and root zone temps versus air temps...
what im trying to get across is that something like your local weather patterns changing can have a big influence on whats going on with your plants even indoors in a climate controlled space...and seasonal changes can also greatly effect your waters mineral balance and pH...

Yup just Epsom salt and water in that fancy bontanicare bottle. I just bought 12lbs of the stuff for 6 bucks, doesn't have a fancy label though.......
technically no one who grows indoors is using "soil"...im actually a medium based hydroponic grower...
lol,the whole organics thing just cracks me up....white people are kinda silly about it and rarely examine the actual cost to the environment or possible social consequences....as long as their spoiled little montesori brats are getting there quinoa crunch breakfast cereal with organic soy milk who gives a fuck whether some quecha can afford their native grain? as long as you used a reusable shopping bag and stuffed into the back of your prius on your way to spin class its all good...
