well i gave them some epsom salt. the top bud colla was burnt by the light. the lower ones are just dieing off. and yes im not useing bllom nutes i was using miracle grow plant food and miracle grow soil an had a nute issue so im kinda afraid to add bloom bosster will it hurtlooks good but it doesn't look like you are using bloom nutrients. I see a combo cal/mag and nitrogen deficiency. Get on that or you will have a diminished yield and lower potency.
