I’m currently growing Skywalker OG from ilgm and it is super big and bushy and appears to be real healthy but it also has red stems. Possibly genetics? I’m going to up my calmag per recommendation I read on this post and see if that helps. Good luck I’ll be watching. Thanks for the Post. Fyi- If it addresses the red stem issue I will reply with good news or bad news. I’m leaning towards red stem genetics just because I add Cal Mag already at 5 mL per gallon. As for your spots on your leaves I’m guessing a pH issue causing a deficiency? It looks similar to stuff I’ve had in the past. Some more knowledgeable growers than i am will have some answers or recommendations too, I’m sure. I’m still learning myself . Have a nice morning

I agree with @Laurap. Looks like cal/mag. Definitely add some to watering and when using tap water adjust the PH to 6.1 for better absorption.

Wat kind of bark is that? If it’s cedar I would get it out of there. What’s ur runoff pH and ppm?

Your ph is a bit high. Top ph for soil is 6.8.
