Just noticing these yellow spot in middle of fan leave on one of my outdoor potted autoflowers. Incidentally, today I noticed the beginning of flowering. Could it be deficient of flowering nutrients? Thanks

Give her a little phosphorus and you’ll be fine - I’m assuming ph is on point of course and you’re feeding some calcium every so often?
Flowering nutrient or do you have something specific in mind?

I mean depends what you’re using. Bottled nutes should be pretty obvious right but organic options would be bone meal… works pretty well as a phosphorus booster. Seabird guano is another.
I dilute 2 tbs of bone meal in one gallon of water, set it out in the sun and make tea. The last time I did this I added 2 tbs of Humic/Fulvic acid concentrate.
