It means you can feed a little bit more with nutrients. let's try to raise up with 200 ppm to see if it goes to be green. good luck.

White bumps/lesions on stem base Day 19 veg auto, is it an issue?
White spots/lesions growing on stem base but not on leaves or anywhere else? This started within the last 1-3 days. The stem "splitting" on the skin was present since it was sagging and bounced back fine. Worried this is mold/infection from soil. Packed more soil onto the top (!)

Nutrient burn, Light burn, or Phos Def? red stems purple bruises,
Noticed red lines leaking red into the leaves with purple bruising, and the starter bottom leaves seem to be turning yellow, with the leaves above looking dark green with spots. Is this signs of light burn or nutrient toxicity? And is it lacking phosphorus or just the strain gen?

Purple petioles and cupping down
So, after watering with root+ 1.3ml/gal and amino extreme 1.4ml/gal and putting in a light that is double the wattage from the one prior it seems they got light/heat stressed. The purple petiole color could be phenotypic as it's striated in the stem too but I'm not 100%. Help?!

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.
Older leaves have brown/red rusty spots and looks like dying tissue in between the veins. Burnt tips, and yellowing leaves. The soil was really dry and my PH meter was 0.4 too high. I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff. Runoff was PH: 6.1 EC: 0.8
