not sure whats going on new to growing and it seemed to be going well now>>>> yellow edged leaves and curling the new growth seems stretched and the more mature leaves are single leaves HELP
i would say either nitrogen burn or a ph imbalance. here is why
a sign of nitrogen burn is your leaves can become real dark like your in the pic(although some strains naturally have darker leaves). the tips are also burnt which is another sign of N burn.
another possibility is a ph imbalance. your leaves look a bit deformed which is a sign. also if your ph is too low, your plants may be taking up too much nitrogen which could make it seem like its too much N.
another possibility is heat stress. what are your temps?
i would flush it with plain ph balanced water. then maybe add a little water with some super thrive or fox farm big bloom. anything that has a very low nutrient ratio that helps repair roots.
always go light with nutrients. i recommend half the strength the instructions say. at least until the plant is big. less is better believe it or not. a lot of these nutrients are made for big gardens, not small grows so use very sparingly.
To piggyback off skiweed, definetely an abundance of nitrogen, first thing I thought. If you're not under a high power light source, like a metal halide, the plant isnt going to consume the amount of nutrients you might hear people suggest otherwise.
About the only thing you can do is give it a massive flush. Pour slow, use warmish water.
Probably a bunch of other problems too, but start there.
