Humidity - 55%
PH- the last few times was around 5.5, 6 now at 6.8, 7, and staying stable at 7
Watering Method - boiled, cooled and purified water, hand watering(no nutes currently) but was using nutes(100%) from 2weeks in till about 4-5 days ago, when i flushed, transplanted, and renuted(50%) now have been just giving water for the last 5 days, still see new spotting,

just an update, the spotsare moving from the bottom of the plant up, and started to develop, the day after transplanting on the oldest foliage first on a fan leaf, near the center vein, before nute solution was added, the soil was pre soaked in Thrive-Alive b-1 to reduce transplant related stresses, had the same thing happen before, been using CalMag, i may be over doing it with it, and messing up the ph causing nute lock? and or MG def.? also how do they look for 3.5 weeks? size? growth? ect...? HELP ME!!!!

i would say that its most likely your PH causing your problems. Only because i have a couple seedlings i fcuked up by adding tap water PH around 7.5.

If i was you, i would not boil ur water, just leave it out for 24 hours to dissipate the gasses/chlorine, and adjust ph to between 5.5 and 6.5. to fix my seedlings i added water PHed to 4 because my runoff was actually up there around 8 or above. After flushing them, they started growing again. hope this helps a flush couldnt hurt
