Leaves curling in

[Twelve12]

Hi, my plants is growing nicely in FF soil and nutes. I noticed that after applying the nutes few days later the edge on the top leaves started to curl in. As you can see on the pic. Can anyone tell me why it's doing that?

Hello
A little Too much fertilizer. Cut back on your nutes. Flush your soil.Also could be a heat issue. whats the temp in the room? heres a good thread: Plant Abuse Chart.

Thanks for the feedback bucktoothal. Temp is at 85F here in the room. I have two fans going still quite hot. The light is about 1.5-2inches away from the plant, CFL 5000K. It seemed that the plant is not ready for extra nutes since the FF soil contains quite a bit; bat guano, worn casting, etc...

Thanks for the link to the chart, I've bookmarked it.

I don't know if this is the case, but did you place the plants outside in the sun for a bit? It looks like heat stress but it could easily be too much fertilizer.

It's heat stress.
I moved the CFL lights up a bit 6inches from the top and it's doing much better now. The leaves opens up.
