Northern Light Auto by CrossboneGenetics

Well I thought I had the issues from last week fixed, but the leaf spotting came back mid week. So I ended up adding some cal-mag, which is something I usually don't use, but everyone I showed pics to said the same thing so here's to hoping it works! Will know if it doesn't keep spreading. Still only really effecting the two plants without airdomes. Wonder if it's something to do with less oxygen in root zone? At least they're looking happier now, even the smaller two perking up for most of lights on. Plants still dropping hard 3 hours before lights out, so am keeping the light at 550umol/s to see if that helps. 21.5"@80%. Could be that maybe they just need a bit less light than some other strains I've done 🤷‍♀️. Otherwise environment is on point, and the two plant with domes are rocking it right now. Happy and lots of bud sites filling in. Here's to hoping we got stuff fixed with the nute adjustments and will keep a daily eye on the res PH
