small plant poblem, has yellow leaves and brown edges..PICS

What kind of soil ya in? Did ya give them any ferts? Whats the temps?

i dont have a thermoteter...ambient room temp...its in a garage with a fan.
no ferts.
and im useing miracle-grow potting mix

Its probably the mg soil. Its hard to grow in.
If possible i would trans plant them to different soil.

Whats the lumen output on that bulb?

I don't see it being more then 600 and thats if its high-output you should consider upping the amount of light.

i have had the same problem all i did was let the soil get pretty dry to the point were plants were droopy n in need of water then i flushed out n quit adding nutes and everything looks great nowbut just like furious g said u need a minimum of 7000 lumens per plant lol so 600 aint shit so deff add more lights or throw it outside during day time hours

Ya, that mg can be somethin else....I mean the plant in the pic looks burned, either by nutes, or heat. from what u say ur using for light, I find it hard to believe it's from heat unless u put the light ON ur plant, lol... I feel this is the main problem with mg soils, once the plant is burnin, then what? U gotta water sometime and u just know everytime u water that stuff it's just gonna burn em even more. I think u may need to consider transplanting to something else as far as soil, and adding 3 more of those lights u got.
