how often to feed

can anyone tell me how often to feed my plants they,re 2 weeks into flowering feeding them Big Bud twice a week just now going to start with Dutchpro EXPLODE next week. all advice welcome cheers alih

i generally feed once per week and water only once per week. so every 3-4 days they either get fresh water or food.

when they look unhappy feed them. If the roots are dry then water them. I feed my plants when ever they look anything but 100% green.

thanks chaps
