I wouldn’t be to worried unless it spreads over the plant more then that one spot. What’s your humidity in there

Hi nulph,
Iv never done an outdoor grow but looks like the start of phosphorus deficiency..?
I could be wrong but I'm sure someone on here will point you in the right direction.
All the best

I was thinking a short on K at first but Turbo is right as I was able to just barely able to see the main stem in a pic yes it does appear to be asking for phosphorus. K isn't a bad idea to give though at this stage. The plants nitro content is so good. Really love that shade of green, so healthy looking. I do see some slight blotchy chlorosis and would ask has the plant received any chlorine? If not it could use a little. Potassium Chloride would be a great additive right now.
