Are my leaves nutri burned???

Ok so Im a newbie and this is an experiment so i can get better, they are just bagseeds . My plants (2) are in the vegetative stage (Same Pot ). I water them about a cup an a 1/2 or until the water drains from bottom so almost 2 cups. I water them every other day in the late morning. Im using typical potting soil. Soil nuetral and water ph 6.0. Two CFL lights one 45 Watt and one 26 Watt, the lights are about six inches above the two plants.

So heres the deal I messed up after giving the them the recommended dosage of MiracleGrow All Purpose Food it said on the box ooops. They didn't like I think because now the edges and tips of the leaves are black. The newer leaves seem to be alright. I just want to know if this is nutri burned. I have some pics there off my phone so the quality isnt that great.

Thanks,

i wouldnt really worry about it plant looks healthy

also you really sould not put 2 plants in the same pot! your roots will get root bound very quickly!

yeah plants look good just would stick to regular water no nutes for a lil while till there all green again, and two plants together is gonna be your biggest problem id spilt them up asap but it could be too late for that might kill one if ya do

Thanks, for all the info everybody I think I will be staying away from the nuts for a while, and make sure to give a smaller amount than the recommended amount on the box, Im thinking probably less than 1/4 of what is says on the box.

Yeah on the two plant deal I did that because the first seedling looked really deformed when it first sprouted Really deformed, ugly lookinig leaves. So I dropped another seed sprout in the soil just incase but It turned out to be a pretty nice looking plant. So I just kept both of them why kill the other. I guess I will be going to the dollar store lol for a bigger pot and soil fack. I just hope both are girls, because of the once deformed plant split in two and I think it would have two nice colas.
