Strains: Blue Dream and OG Kush
Environment: Indoor Basement Grow/ RapidRooters/ Hydroton / temps between 65F-75F
Nutrients: GH Flora Series / Flowering dose/ changed every 14 days
pH: 5.7-6.0 (tends to start rising around day 12 before solution change)

plants are 5 weeks flowering today
went into 12/12 on 12/15/11 and both were showing lots of preflowers prior to the switch
actually started budding on 1/3/12

on 12/7/11 i placed a small electric space heater in my flower room b/c my temps were dropping too low at night due to the temps outside being in the low 30's the space heater between then and the 13th somehow got kicked in front of the buckets and the solution evaporated down to an inch well before time to change it....when i found them on the 13th they were VERY wilted and so i immediately changed their solution... by they next morning the BlueDream appeared to be back to normal minus a little irreversible leaf damage.... the OG however still looked awful....no 5 days later and no improvement to the OG and the BlueDream is now starting to develop the same spotting on the leaves.... there doesnt appear to be any pests or mold and the roots of the plants are very white and healthy looking.... is this just heat stress from the water getting too warm? or is it some kind of deficiency? Any help is GREATLY appreciated! THANK YOU! :)

back story:i had 5 other plants flowering in the same space 2 weeks prior that were showing the same symptoms i was told that it was a calcium deficiency and so i added 1/8 dose of cal-mag plus to each of their buckets by the next morning all 5 were damn near dead and i had to harvest 2 weeks early...the cal-mag created some sort of neon green chunky mold all over the roots.... i did not however add the cal-mag to the blue dream and og...

picks 1-5 are of the OG and the rest are of the Blue Dream

You've got a I'm a damaged as fuck plant that's crying to stay alive...if the capillary action in the stem was damaged from the nutrient solution going away and leaving the roots exposed so long she might have such irreversible damage that it may never recover...i'd give it another week to turn around...do you use any h2o2?

thats what i figured ill add some and give her a week.... do you think there is any chance of letting her finish or at least get closer to harvest? or should i just trash her? i have 15 of her clones so its not a total loss.... also... what about the spotting on the Blue Dreams leaves?

those spots between the veins usually come from a cal-mag issue...so it either isn't getting enough or its being locked out by PH...
