Yes, it's cocomix and fertilizer from Biobizz. The pH was at 6.4. I noticed similar symptoms on another plant after watering and watered again with pH 6.0. The purple spots have since disappeared there. Thanks.

The first picture shows fairly typical damage caused by the leaf touching the surface of the substrate and is not really something to be concerned over, it will not affect growth rates, potency or yields.
Some strains have naturally occurring purple/reddish leaf stems and I very much doubt that there could be an excess of nutrients this early in the plants life.
Hope this helps, Organoman.

Need more specifics. Are you growing in coco? Looks like it. Would say ph in coco is likely too high. Measure run off ph . Plus coco needs to stay moist while grown in. Good luck 🌱

Deficiencies? Brown spots, yellowing and purple stemsWhat is this deficiency or maybe toxicity and whats the solution? She is fed with biobizz chart instructions but with every other watering. She is big so I'm guessing I should water with nutes every time? She showed this first week into flowering.

Calcium deficiency or overfed?Hi.
This is about my Apricot Auto which already suffered the yellow tips/edges. I took that as the result of heat/light stress.
Now she also developed discoloration and brown spots on some of the leaves. It looks like a Calcium deficiency to me, but I am quite uncertain.
Thanks!

Necesito experto! Double cookies auto BSFI had excess N at the beginning of flowering, I did a root wash and continued applying fertilizers regularly, today it looks like this. A lot of green smell but not from flowering, leaves with necrosis, I'm in the final stage of flowering and it's still vegetating with leaves in good condition!

I think I have nut issues?OK here's today's update, 3/9/22. They are all doing great, they're all standing proud now! I think they needed to dry out a little, more light and needed the extra nuts. What do any of you guys think could've caused these symptoms that my girls are/have shown?

IDEAS?! double cookies auto BSFI had too much N at the beginning of the flowering stage, I did a root flush and everything got worse! Now, almost 1 or 2 weeks from finishing flowering, she looks like this. After the root flush, I continued with fertilizers normally just like the others and the others are in good shape!
