High everyone; little help please

high everyone, hope everyone's feeling great!
just started growing. first few harvests were great: thick, heavy buds; now buds are "stringy" and skimpy. could it be humidity? also just changed fertilizer. was using powder bird guano; now using budswel organic tea, which also has bird guano, so I can't see how that could make a difference, or could it?
Also, anyone have any review or opinion on LED lights?,
any help would be greatly appreciated,
God bless,and the blessing of the saints with you all

every thing I have heard about led says no go!!!! still need to perfect the science I think... there have many threads here on the subject and prevailing thought seems to be that they are not so great..

as far as your stringy buds go, any chance you can get a pic uploaded.. would help to see it.
