lower leaves slowly yellowing in the middle w/ small brows spots , purple stems

i have a female and shes having some uncommon signs, other plants (diff strains) are doing good w/ exact same conditions. also its weird that the leaves arent falling off, or getting crispy, just yellowing on the middle and on the veins of the leaves, and on the smaller of the leaves brown/ reddish spots pop up, also in the middle. also it has purple stems.

purple stems can be caused by many things such as temps, genetics. but yellowing leaves normally spreading from the middle i would hazard a guess and say magnesium deficiency.

hmm, ya it does kinda get hot in the room, normally have to leave the door open so the fan can blow out the warm air. dunno ne other way to cool it down. but yea so how would i go about fixin a mg deficiency

I'd say more like a N, P and Mg deficiency. Hungry plant.

Hungry for sure...epsom salt worked for my MG deficiency. just do some research, cal-mag is better than epsom salt if you can get it... could be a Ph lockout.. if its lower leaves affected then its an mobile nutrient deficiency.. NPK defs show themselves at the bottom of the plant because they are mobile within the plant. what nutes and such are you using?

i'm sorry to jump on your thread but i'm having the same problem.......bottom leaves are almost yellow and the top leaves have brown spot in the middle of them and the tips look reddish brown as well.... I'm using nova bloom, floralious, liquid kool bloom, and pineapple rush. The plants go through a gal of nutes in two days so i thought i was over feeding them bygiving them nutes that much so i flushed with nothing but ph bal. water and it seems to hav gotten worst. I'm 5 weeks into flowering and the buds are coming along nice. I dont want my plant to die this close to harvest. should i go back to feeding them every two days??? any info would be appreciated!!!!!

i started off w/ a mix of Miracle grow blood meal, and bone meal mixed w/ organic choice miracle grow which lasted to veg and now its 3rd week flowering and ive been watering w/ 15-30-15 half mix of MG bloom busters every 3 days or so w/ watering. all my other plants are lookin great. heres more photos, couldnt take last night when they were sleepin. so u still thinking Mg? and up the feeding dose of bloom?

also i just got some ph drops and checked my runoff, and it seemed like it was basic like 7.5-8 (not knowing how accurate that is though), also since i was testing around i checked my fert (bloom busters) and it was like 6.5 acidic so i dunno, id think it'd be correcting the ph problem itself since i started fertilizing like 3 weeks ago? the yellowing doesnt seem to be moving up more atm, but even the top leaves kinda curl weird like the bottom 1s.

just to keep everyone informed, im adding some molasses to test out the denser buds theory, also has Mg in it so maybe itll help my plant out? coincidence or not im gonna try it!
