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
 
looks a lot like P def.
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.......check your ph. alkaline soil is the leading cause of P lock-out, and lock-out is more common than straight-up deficiency, imo.
