Thanks

I would need detailed info to answer, here's an example of what would help us & a picture for you

Consider putting as much of the following information as possible to start the thread with.

What strain is it?
Is it Indica, Sativa or Hybrid? What percentages?
Is it in Veg or Flower stage?
If in Veg... For how long?
If in Flower stage... For how long?
Indoor or outdoor?
Soil or Hydro?
If soil... what is in your mix?
If soil... What size pot?
Size of light?
Is it aircooled?
Temp of Room/cab?
RH of Room/cab?
PH of media or res?
Any Pests ?
How often are you watering?
Type and strength of ferts used?

This info will make it much easier for accurate help to be given when needed and keep the members interested in your grow.
