4th week of flower....spots on leaves, HELP!

I've come too far for this crap! I'm on day 29 of flower, and I have spots on some of my leaves...wtf is it? I am using FF trio and following the feeding chart. Is it nute burn or deficiency?

Another pic

Anyone?

I'm thinking calcium deficiency, but I'm a noob

Check under leaves and get back to us... any webs near base of plant stems? I'd hate to say what I think....but it looks like spider mites. I hope not man... but neem oil will help....

Either Calcium or spider mites. Are you giving CalMag?

Just give sharpshooter pest spray should work could be worst could be bud worms

Not giving cal mag, and I don't have any webs...gonna check the bottom of the leaves at lights on in the AM

Just ordered cal mag too....giving one dose during next watering....about 2 or 3 days away

Yeah hard to say with the HPS light on take another pic of the whole plant if possible as well but,
That for sure looks like a slight cal mag def cannabis plants really like their Cal Mag buuuuuut, That really fucking looks like slight spider mite dmg as well.
I highly suggest looking on the underside of all your leafs, try misting them with water to see if there are any little webs lingering around.
DO THIS SHIT ASAP! As your well into flower and this is the worst time to be getting a deficiency or worse spider mite infestation.
Wish you luck and Hope its not mites and hope this helps

What color are the spots?

They are brownish, I think....I'll know more in the morning...it's killing me that I can't check on her right now....what's weird is its only affecting one of the two plants I have in the tent

Praying it's not spider mites...

Same strains?

No, two different strains, not exactly sure what the strains are, but seeds were ordered from reputable place they just got mixed up by a butt hole brother....chanced are one of them is Afghan kush, or an Afghan strain because i bought mostly those. I think the taller, unnafectted, one is bubblicious based on smell

Good to hear. Most likely ca:mg then. Add it to watering cycle, probably wouldn't hurt to add some liquid seaweed as well for trace minerals, auxins and cytokinins.

Thanks a lot, overall do they look ok? WI'll I get a decent yield?

Overall they look good. Could use a pk bump #imo to fatten up some. Day 21ish and day 42ish they like xtra pk.

Ca:mg is one of if not the most common def out here, all most everyone gets/had it. So keep a ca:mg source handy.

Seaweed gets slept on but makes plants happy and hard.

Keep it up.
