I have 18 seedling going into 2 weeks from sprout and about 10 of them have pm on there cotyledon leaves don't know what to do ive never got it this early. but I figured its better to catch it early instead of when im 6 weeks into flower.

best thing to do get some ventilation going. I run fans 24 hours a day 7 days a week ! very important even in flower those fans never shut off and circulate the air with out side air keep it moveing and fresh. . or at least get a dehumidifier, this is the best way to prevent mold, if you already have it. 1 teaspoon bleach per gallon water and hand wipe every leaf, you need a dehumidifier and fans to be successful ! with high humidity . you may get bud rot from the inside out you wont see it until its to late your fucked,
thanks my fans already run 24/7 RH between 45 and 50
I fight PM with several products. Serenade is good, as is Neem oil and milk. I rotate the products and use them every 2 -3 days if I see PM. You'll have to spray under the leaves and all over the plant as it's only good on what it touches. BTW all three of those products are organic and are safe to spray and eventually smoke. You'll probably have to spray each at least twice to hope to basically rid yourself of PM and then once/week as maintenance. The Neem oil is good for spider mites too so will help to keep then at bay as well.
The milk is mixed with water at 5:1. On the other products follow the label recommendations.

More air flow, if your foliage is to dense it will block a lot of the air flow.
Preventative measure
I have plenty of air flow 400 cfm inline 3x3 tent and two 12in fans inside blowing things around but like I said these plants are just seedling the biggest only has 3 sets of leaves

I'm afraid PM is impossible to eradicate once your plants are infected, it can be worked with and kept at bay but you can never get rid of it.
You can combat it by spraying your plants with a whole milk solution, 1 part whole milk to 9 parts water.
The best thing to do really is destroy the infected plants, clean down your room and start again.
