Leaves Have Curled Edges!!

i dont know if this is going to affect the plant majorly, because it is still growing extremely fast. But the first set of leaves that have come out have got curled edges and brown tips. what could this mean??? I have noticed the rest of the plants leaves are fine? it is only still a seedling and its 2" tall. the new growth appears healthy and its developing on its third node and growing fast. possibly the problem was only within the bottom two leaves.
Any help appreciated.

i am using organic liquid seaweed and tomato feed, and using the instructions on the pack for the seedling portions.

The brown tips, if they are at the margin and not large, just a little on the edge are signs of root growth. not a bad thing. if the brown spreads more into the middle of the leaf, then it probably is something else. as for the curl, are they curling up or down? are the tips crunchy? I'm now thinking it might be underwatered, but it's hard to diagnose without a pic.

the brown bits are on the tip of the leaves, and the edges are curling upward. they are not crunchy.

upwards is a sign of underwatering, she's thirsty, and the brown is the root growth. The roots are stretching and are trying to get water. If you want clones to root quicker you let the tray, not the medium, get dry and the roots will come out seeking resources. if you don't think it's the water, if you water everyday lets say, then you'll have to wait and see more signs.

well if there are those two things happening, it probably is underwatering. it is a hot light so i can immagine it drying out fast. i have just gona and watered it and put vermiculite over the surface for insulation.
Also, i am using an old 1litre juice bottle to contain the distilled water. I can still smell and taste the juice that was left over. i boiled the water before i used the bottle to get rid of anything left over. could this now sugary flavoured distilled water harm my plant??

highly unlikely, however are you only giving them distilled water?
