Can you post any pics by chance? That will certainly help to figure-out/rule-out any possibilities.

Also, please include your:

-grow area setup
-lighting (type, distance from plants, etc.)
-watering/feeding schedule
-type of soil (or hydro setup)
-other factors that you may think of.

With all of this info maybe we can figure out exactly what's going on and be able to correct it.

Here's to healthy grows.

Peace
