Hi guys what are those spots on the leaves of my c...

looks like calcium deficiency, could also be some spotted fungus, but I guess it is calcium/mag def. what are you feeding them, what is the ph? if those are just rooting, don't worry, that is normal.

Cal-Mag appears to be missing broo

Cal/mag. Check ph first, generally the red in your stems indicates a mag deficiency.

Id say nutrient burn, less food! The leaves tell all you’ll need to know!

Calcium spots Check PH and/or increase Cal-Mag Since they in veg you can foliar spray, use a mister full dose of cal-mag (most around 2.5-5 ml/gal) I just make up a gallon its cheap this will get things up quickly

Anytime I have those type of spots, it was either pH fluctuations or calcium/magnesium def. Hope that helps

These are usually difficult to identify, so find some cannabis deficiencies charts. Could be a calcium deficiency. If you're already giving them enough cal-mag, then stop to see if it stops showing on other leaves. If you're not giving cal-mag, treat the medium with the proper amount. If you added more calcium to your medium than needed, it'll cause a nutrient lockout.

Whatsup growmie! 👏 I'm very new to growing myself but to me it looks like it could possibly be too much heat. Looking at your grows I don't think I am in a position to give advice though lol. Happy Growing 💪

Ciao buongiorno, potrebbe essere eccesso di nutrimenti, misuri ph ed ec della soluzione?

Try a good flush and then adding halve of your nutes as it seems your plants are showing signs of nutrient burn. If your growing in a coco and perlite mix, it should be a quick adjustment to make. Good luck and happy growing

I had same exact thing except it gets worse if it is what I think it is. Too much flowering nutrients, not sure what stage you're in. Whatever you're giving it cut the dose in half, I mean do half of what manufacturer recommends then see what happens. Is it mainly on the upper fan leaves? Just a guess. Sometimes these nutrients are just too much.

Thinking maybe phosphorus? Seeing some purple stems/petioles, it looks like. My clones always show some signs of issues at some point from cutting it to being fully rooted and vegged out. They can take a decent amount of nutes so if you’re going light, I’d up your nutes overall.
