    Well they're autoflowering so they don't need a lot at all before flowering. But I added 1/4 strength grow after the second set of leaves was in and the third was coming in, and then 5 days later i added 3/4 strength. After that was when I started to notice the burning edges of the leaves. I don't plan on adding more nutes till I see flowering (which should be within the next 3 days or so). As for res size, I'll definitely be upgrading to a 4 or 5 gallon tomorrow.

    nute burn was my second guess. if that were true, would adding the CALiMAGic be a bad thing? or will they recover over time as I add more water and dilute it out?

    bump? if nute burn were the cause, would adding cal/mag be a bad thing? the plants seem to have stunted growth a little bit, and the lower leaves are "burnt" around the edges and have small yellowish spots on them

    Imo the important thing is to keep total ppm down. You experienced trouble going from 1/2 to 3/4, so dropping back to 1/2 is good imo. Also, I would not add the CALiMAGic unless or until you see signs of cal-mag appetite. jmo. cn
    ps: sorry to not respond sooner.

    <edit> Oh good news on the save!!
