so the plant is indoor in a room very exposed to the sun i have a lamp but it is very weak.Hey m8.. so you're growin this lil lady outside yea?? If so how many hours good sunlight are you getting.. I've never grown outside as conditions aren't good enough.. ever.. but I would imagine your gonna need a good long days hard sunshine most days to get a result??
the best result I had (and they were bad) were with natural light
