Bud problems

Hi My plant buds are browning out very early, only about 40% of them, any ideas? Also I am using a low Bay SON light of 70w but the light keeps overheating and switching off, had a new Ballast but still the same. All help appriciated, and thank you in advance.

got a microscope to check the trics? what strain are u growing? it could just be the colour of the strain

i think its because your light turns out... hairs is browning in dark..

hairs also get brown when underwater
