dont want to jack the thread but i have a similar problem, my plants are about 3 weeks in as well. the light is not the problem i have a 10 foot ceiling. the problem is my bulb started losing lumens which caused them to stretch a crazy amount making them too big for their containers. bulb is replaced. they are now over 7 foot tall and the small flowers on the main cola are very tiny and fluffy while the lower half of the plant has compact buds that are fattening up nice. is it possible the plant is having trouble getting fluids to the top? I am really considering taking off the top 2 feet and getting the bottom half of the plants closer to the light since they seem to be doing much better.
what are you thoughts?
once again not trying to jack thread it just seemed the original poster was all squared away.
thank you
