I have a 4 ft t5 grren bulb for working in my room during dark period, been using them for almost 4 years withoit an issue until recently.

I purchased a new bulb before this current cycle and by week 4 i was freaking out becuase my plants did not appear to bud as expected, by week 5-6 they had visual pop - corns like that that of whats typical for week 3, so i started noticing that all the tops that were closest to the green bulb were the more underdeveloped bud and buds furth away or hidden from it were alot further along.

So i killed the light and in a week noticed way more developement on sites that were underdeveloped .
