Phosphor maby? I have the same issue

Did you reveg?

I had 2500ppm drain so i quess locked out potassium i flushed to 1200pm and im feeding soon again !thanks for the tip!

No cutting! Outdoor plants get enough light and air movment

To mutch has burns on the edges like mine do ,in so i would give slightly more

Drop the ph slightly but aslong its only that one old leaf i would not worry about it

Feels like a magnesium issue but as always first check ph of the drain (6-6.9) and if you can ppm with an ec meter if its overfed

Not mutch to do when growing outdoors

Old r12 refrigerator oil

Looks like to mutch food?

I wish my climate would alow outdoor grows mit centeral europe is a pain no winters,no summers just grey wet cold 70F with a change of a random 100F heatwave

I think you will be baked all summer!

Maby low on magnesium?

Check ph maby looks like low on calcium hows your tap water?

How mutch ppm is the drainage? Mine looks just as bad a while ago and it was overfed

Just flush and harvest at sole point i dont think theres mutch to do anymore

Since its a photo im quessing it will keep growing till daylight is redused to 12hrs so its gonna fill up your balcony and start flowering in septemper i quess you can cut her up but dont overdo it outdoors she will be fine

So little cars what a time to be alive

All good so far just keep growing still weeks left

You have to wait

12 weeks at least🤣

If you water it down to 10-15% it will freeze

Trim and use the leaves for tea dont get you high but tasty and you will fall asleep

Check ph or too mutch food
