newbie with a sick plant, help!

I started 6 white widows in jiffy pots. all 6 sprouted and I put CFL light on immediately at 24/7 after sprouting. Got some real fast growth, and the 4th pair of leaves for my biggest plant too. These were all planted in the pods 2 weeks ago tomorrow.

Now for the problem, while in jiffy pods 2 of the plants started to develop a couple small yellow/brown spots near the edges of leaves and looked a little droopy. So then I made the big move and planted all of them into larger pots, using miracle grow potting mix/moisture control. That was about 24hrs ago and the drooping went away, but I've got small brown spots on the tips of the biggest leaves and a couple little spots on the edges of another leaf. Any ideas? I looked at the other threads on problems and was unsure as to what the actual problem was for me. Thanks for helping a newbie out!

mg can cause burns and a few other things to seedlings, its probably just the mg soil.

is there anything I can or should do to help it out? I just don't want this poor thing to die, it was doing so good! thanks a lot!

try watering with ph'd water do your best to keep it between 6.5 and 7 no nutes and 7ml hydrogen peroxide O2H2 per gallon. and don't nute untill your first set of 5blade leaves appear. u might try flushing it to try and get out the nutes in the soil.

if that doesn't fix it. i would just try repotting with a nutral organic soil.

so I would literally take 7ml of hydrogren peroxide and add it to a gallon of water? Also, when the time comes, what nutes should I use if I keep up with the mg soil?

This is a weird question too, I have a hot tub and we have stuff to either increase or lower the ph of the water. Could I use that to adjust the ph of the water for my plants or is it a different situation completely? and would the same ph testing strips we use for the hot tub work well for my watering? Thanks for all the help Dr. I'm just trying to learn as much as I can, as fast as I can. I want some pretty widows lol

yeah i think its like a 1/4 tsp. as for nutes something well balanced for veg like a 3-1.5-4. and i wouldn't use the ph up or down from your spa but the ph test strips would work.
