Spots on my leaves :(

Been noticing some spots it's been about a week I thought it would just go away if I watered it and the normal stuff but it hasn't and I'm looking for a diagnosis if anyone can help. It's a sativa dominant that's 5 weeks into flower. Also seems to be accompanied by some buds not filling out. Any help thanks in advance :)

Looks like you got spider mites. I would foliage spray and keep those plant leaves wet when you can. Maybe try diluted dish soap (bio degradable don't use bleach...)

That doesn't look like spider mites to me, It looks like cal/mag deficiency, maybe due to nutrient lockout via over fertilization or PH.
Are you growing in soil? If so have you checked the PH?
 
That's more along the lines of what I thought yes I am using soil the ph is between 6.25 and 6.5
The spots do look like calcium def but I wasn't 100% sure

What are your temps at and how close are your lights. I'm not looking at the spots (which very well could be corrected by calmag) but at the rolling up leaf edges in pic 1 and how the bud in pic 2 looks like its fox tailing.

Also what nutes are you using and what is the npk ratio? I think you have a couple things going on at once.

Just using miracle grow moisture control soil with 21 7 14 NPK no nutes since it already has them and it nute burns quick when adding soil... But what is your best guess on what's going on? I'm using neem oil regularly also

I'm using an xgs 190 and I had them 14 inches from the top when recommended is 18 I raised it slightly a couple days ago and the spotting hasn't improved

Unfortuantly its probably what first thought was. And that's too much N in flower causing foxtailing and improper bud growth. Too much N in flower will cause foxtailing and those glossy dark green leaves like in pic 2 are another sign of too much N. Also there probably isnt enough P to support vigorous flowering. So... you have an abundance of N, not enough P and possible lockout of calmag. There's not much you can do that I know of about the N since its in your soil. Perhaps another grower that grows in this miracle grow can chime in with a solution. This is why I don't believe in growing in soil that has time release nutes, there's no way to get it out. As far as the calmag defficiency goes I would foliar spray calmag. One with no added N. There's an organic line that escapes me right now that contains no N. I reccomend foliar because its quick and the last thing you want is more N uptake from the soil. Too much N could be contributing to the calmag lockout as well. Good luck and pick a medium that has no added nutes next time.

Oh and heat was what I was worried about with the tacoed leaf edges. What temp is the canopy at?

hi, i think biobizz algamic might help as a foiler feed in the sense that it can help with calcium deficiency whilst not actualy feeding any n into it, got no idea about the miricle grow stuff but couldnt you give it a good flushing?

Don't flush!!!! You'll release more N from the time release soil. Flushing compounds problems like this in time release soils

Ugh this is such a struggle I've done half a dozen plants in this soil with relative ease it's grown some really nice stuff for me... Idk I think I just need to save some money and go for FFOF

Also I thought too much nitrogen would cause dark green leaves?

Of certainly does most of the time, like the leaves on the bottom of pic 2. Perhaps post a pic of the entire plant for inspection. With N toxicity the oldest leaves are the greenest and glossiest.

Here's a pic of the full plant it's 31 inches tall
Note: pic was taken during its dark cycle 2 1/2 hours before the lights came on

Well it deffinatly doesn't look super dark green. I'd start with the foliar calmag and look for spotting to stop in about 3 days.
