PM?? not too sure help please!

on other leaves there is pm, im new to growing and dont know what sprays are safe/organic. I just changed over the cycle to 12/12 and they have vegged for 10 weeks now in a tent, what would be the best course of action to take with this, i want to stop it early before any budding starts =) ive already added an extra fan so theres great circulation and the temp runs about 65-70. let me know if you need anymore info cause im not sure what else you need

so im guessing the obvious solution would be to add more phosphorus to the next feeding? BTW i am having a pm issue even though you cant see it on the pictures i posted, would someone kindly suggest a safe spray method that a beginner can do without harming his plants

no sir i have not sprayed them with anything at all

no.......check your ph. alkaline soil is the leading cause of P lock-out, and lock-out is more common than straight-up deficiency, imo.

the soil is just happy frog, how do you test the ph of your soil?

with a ph tester..........*sigh*
this is where i flip backwards off the boat, like Jacques Cousteau

ok so ill go get a soil tester 2maro and then would i just add ph up/down in the next feed to make my ph around 6.5?
