Hi there fellow grower!

Small buds can be from a nmber of things but mainly this one. The amount of time in veg.

How long did you veg em?

Your lamp hieght should be fine just make sure they're not gettin burnt by it

You can never esactly put a strain to a plant from just a picture usualy only tell whether its indica or sativa. Some strains are blatent but im not a strain advisor so i couldnt tell you.

Your pots arent an ideal size but i cant see why this would cause small buds. Would cause smaller plants tho. Also it could just be a characteristic of the strain.

Hope this helps and get back to me

Check on my grow aswell
