Hey horny! This looks like a cal/mag deficiency. I think it looks like calcium personaly.
Use a cal/mag additive appropriate to your growing style. I use an organic amendment that I top dress with. You can make your own with eggshells and vinegar, Or buy a liquid additive from the hydro store :)
Hope this helps m8

Estas fertilizando la planta? Que producto usas y que medidas? Pareciera una ligera sobrefertilizacion que esta causando bloqueo de algún nutriente. Si es esto te recomiendo usar solo agua durante las próximas 2 semanas. Y luego sí volves a usar fértis en dosis mínimas.

I agree this looks like a calcium deficiency. Easiest fix is to add some CalMag into your nutrients.
One thing to add, more for prevention of further issues - leaf septoria looks very similar to this and is particularly prevalent in wetter environments (e.g. 1cm from the soil). I don't think this is what it is, but I would probably remove any leaves that are that close to the top of your substrate as it's just asking for trouble. Other nasties also hide in there, like budrot (which can infect the lower stems if they're constantly moist and then appear on the buds in a months' time) and so it's better to take off any low hanging leaves and keep good air flow around the base IMO.
Good luck!

If it’s just bottom leaves close to soil will be nutrient burn from feeding

Brown spots on bud sites leavesHi all,
I’ve been getting these brown spots in the past 2 weeks, mainly on the top leaves located nead bud sites.
What could this be? Ph is ok, I’ve already tried to flush her, Rh is around 45%.
This is day 65, ~20 more to go. Will this affect the bud formation or quality?
Ty 🙏✌️

Leaves droppingHello,
I have a 2 w old royal gorilla and 2 white widow strains. Today I have noticed that on the gorilla the 2 main leaves started to drop after watering and feeding them with fox farm big bloom, recommended feeding was 6tsp/G. I have given them slightly less and about 100ml.Leaves. Wilting

Brown Patches on Older LeavesSlight yellowing and brown mottled patches.
Only on one of the two plants and they’ve been treated and fed exactly the same.
On some older fan leaves, no signs of anything on new growth.
Anything to worry about at this stage? Maybe just a sensitive pheno?
Any advice appreciated.

Help! Lower fan leaves drying out slowly at the tips and edges. Doesn't look like nitrogen deficiency to me, but please prove me wrong!10 days ago the lower set of leaves started drying out (they get brown not yellow). They don't receive light, but now it's already started showing on the third set of leaves. Does it look like nitrogen deficiency or can it be something else? Just gave it full strength nutes.
