Black spots on leaves (outdoor)

[Parabellum]

Royal Queen Easy Bud, scandinavian outdoors, 2 months old, 4 gallon pot and no extra nutes.

This gal was doing great until these big black spots showed up on some of the fan leaves. I figured waterlogging was to blame, so I cut those leaves off and eventually it also stopped raining.

It's been sunny and hot ever since, but these black spots have still spread like the fucking plague.. More and more leaves are getting them and I need to know how to fight it!

My last line of defence is to repot it with new soil, but the clock is ticking.

Here's another one!

Looks like some type of deficiency. Outdoor grows tend to run out of nutrients quicker when they are in pots.

Ph problem I think - looks like the soil's a bit too acidic. You could try top dressing with lime.

phosphor deficiency

phosphor deficiency

imo yours: phosphor deficiency

And IMO its more plausible that its a deficiency as that its a ph problem cause outdoor there are lots of microorganisms and stuff in the soil which live with and on the plants roots helping her with nuts and also having influence on the ph

yep, deficiency of P. can happen around flowering time. foliar spray with liquid K containing 2% (at least) of P.
assuming the product is available where you live ... ?
