Need a chart for, Growing autoflower in coco.

Hope this helps... https://www.growweedeasy.com/nutrients#best-npk-ratios-for-cannabis check this site out, a lot of great info. Happy Growing.

in coco you must provide nutrients at all times, so you start from the beginning... as long as you wait for top layer to dry a bit and fully water each time with 20% runoff, nothing will build up in the substrate. it will be a well-balanced and fertile substrate. first 2 weeks or so teh seed will have plenty of power packed into it for growth. if not careful with exctra runoff you might create too hot of a root zone. if concerned, start 1/2 strength those first 2 weeks... you'll barely water it anyway... takes forever without the plant drinking from it. you provide everything... the benefit is it should be very easy to deduce problems that might show up. Calculate PPM of what you provide... stick to wet-dry cycle irriations... 20% runoff minimum... all is good. react to plant... adjust formula... no chart will be any better than that.. you still have to react to plant and ajdust formula. instructions just get you in the ballpark for each plant.
