First grow… Quite a few weeks into flowering with my girls and I’m starting to see signs of possible phosphorus deficiency. Second opinions?
I know right now my lighting isn’t adequate and my plants stretched a good bit but I’m tying them off now so they don’t get hurt by the light… New light and bigger tent is on the way but I’ve gotta finish these two. Only the Green Crack is showing these symptoms (red stems, brown spots). The Sweet Tooth has maybe one leaf with a few spots up the vein but nothing more.

I change my red every week and my nutes that go in are as follow for my 14gal:
3ml/g CaliMag, 4ml/g Flora Micro, 8ml/g Flora Bloom, 2.5ml/g Liquid KoolBloom
Had a problem with nute burn in the beginning and everything I’ve read says keep autoflower nutes half or qtr strength. Should I add more Phosphorus??
