Title Says it all im running an autoflower which is 5 weeks flower thursday worrying also that its behind because of previous stresss such as nitrogen toxicity and ph problems that i believe to be now fixed i only think its behind because buds are still small and havent fatted up but anyways the red spots i see it on some of my leaves im thinking maybe potassium deficiency but im not sure i iwill add pics below!

Its a calcium deficiency.
CALiMAGic recommends feeding at 5ml

Whats your ppm of the feed water?
And PH of run off?
And PH of run off?
i have to buy a ppm meter this week if anyone could drop a link that would be nice and appreciated. ph run off is 5.4 my ph in water is 6.3-6.8 i stay on the 6.3-6.5 side though

Yup, that will do it. Your soil PH is too low and could potentially be locking out cal/mag
Add alittle dolomite lime to the top (mix it into the soil next time)
would epsom salt work?

Epson is a good foliar feed for quick delivery, but dolomite lime actually helps bring up the PH of the soil and adds magnesium
where can i buy it
