Leaves yellow and curling

I have 4 clones as of now growing in my closet. I am running a 150watt hps sun system for the light. I have the clones transplanted 3 days ago and are sitting in FFOF Soil. I have not fed them any nutes. Only been using water. I water in a circular motion. I have had them for about 2 weeks now. The ph run-off for the soil is 7.0 and ph of water is 6.5ish. The problem is the bottom leaves of my plants are turning yellow and some are curling. Here are some pictures. Any suggestions?

id say its more likely to be transplant shock, rather than a nute burn...but let it ride for a minute, FFOF is a great medium and those plants will explode in no time

Well they looked the same when I had them in the other containers before I transplanted. Now they continue to be the same yellowish color. I shouldnt have to be adding nutes right?

no nutes, not for atleast a month, depending on strain...

are you over-watering?

Sometimes peeps tend to over-water in soil..And as stated FFOF(being rather hot) needs no food (nutes) for a few wks, or unless the girls tell you otherwise..When I rock soil I usually mix 50/50 FFOF and HF for veg and just before flip I transplant and run the hotter FFOF solo and not feed them for another few wks..Works for me..
Good luck!

I don't think I'm over watering. The plants get about 20oz of water every 3 days. Is that to much or what?

water by weight of pot, not by a timed schedule, imo. yes........i do think that's too much water. they never really dry out getting watered every 3 days.

I do water by weight of pot. But I also stick my finger down a couple inches and make sure its dry before watering. If 20oz is to much ill lower it to 16 next time I do my watering. Thanks for all the suggestions.

Also one more question. How far do you think I should have my hps light away from the plants. They are about 22 inches away from the plants.
