Spots on leaves

[MittenMan]

I'm on my 2nd grow and got some spots after top dress feeding 1/8 tsp of 3-9-6 bloom and about 1/2 cup of worm castings. They were in week 7 when I feed them. Its week 8 now. Growing strawberry cheesecake auto, in 5 gallon pots in coco loco with dry ammendments added initially to soil

. Mars 250 grow light about 17 in away, day temp 78 night temp 69, rh about 65%, water ph is a constant 6.5 watering about 1 liter a day per plant. 2 of my 3 plants have these spots. Any help is appreciated. She has about 2-3 weeks left.

Don't worry about it. If those small spots are all you have then you are good. Some stress about every little brown yellow spot, but with 2-3 weeks left she should be pulling nutes from the leaves. With 2-3 weeks left IMO you'll do more harm than good trying to diagnose/fix this. Keep doing what you do and learn from this grow.
I've had leaves look like brown death and the buds still swell and produce good buds. Stop looking at the magazine perfect plants and know that is not reality for most of us closet/ hobby growers. And it's not necessary for a good harvest!

Looks like it could be the beginning of a cal/mag issue or phosphorus. What is your soil ph?

Just to reinforce what I said about not having to look perfect. Had lockout, and transplanted during flower , and still got 2oz cured from a Ministry of Cannabis Blueberry Dom ( fav stain based on feed back this past year. She grows tall fyi). Matter of fact I fubar'd the whole grow. 6 plants and still got at least 2oz per plant. See the lack of fan leaves, never give up they are resilient plants.
