Tri part nutrients for auto flower purple punch

Stay away from the recommendation dose. Most times them does are to height. So normally with the tri packs you want to cut the ratios depending on which stage of your grow you are at. And you want to go by ppm not ratios like that. You do want to use them ratios as a guide line but make up your own EC feeds For young plants like yours and in soil you only need a feed once a week on a very low EC giving her too much for 2 weeks sounds a little to rich to me. So you are aiming for 4-600ppm water ppm included. And you can either make a 1L bottle and feed once a week say 500ml and keep the next half for next week. But she won't need more than that at this early stage. Now, idk which tri pack you have you the ratios are always nearly 3:1 so if you are using grow and bloom and micro you want your ratios to look something like this .9 grow -bloom and .9micro. (These are just ratios) and the week you are getting ready to flip or you c the change you even out the ratios for that 1st week of pre flower to .9g .9b .9m or whatever ratio works best for you in your EC readings. Always if you are growing in soil you should look into a root stem or enzyme it'll make for better roots and in turn be better nutrient uptake. Good luck pal

You will see on the bottles they will have a ratio. Eg 1ml/L grow, 1ml/L micro, 0.5ml/L bloom for week 1. With light mix there is enough nutrition for 2 to 4 weeks. So when you add nutes for 1st time and let's say its week 3. Use the recommended doses for that week but halve every product as autos don't need or use as much as photoperiod.
