Introducing nutrients to seedlings? Using future harvest 3 part micro grow and bloom

If your tap water Ec is nice and low like Ec0.2 you can run your 1st week with that. The next week introduce your nutrient in the recommended ratios but probably 1/4 strength and when added to your water you have a Ec of 0.4 to 0.6 that will be fine. Then increase it week by week by about 0.2 but remember to do at least one just watering inbetween feeds. With an auto you probably wouldn't get much further then an Ec of 1.2 to 1.4 but with a photoperiodic plant you can get the Ec up a lot more the further through the grow you get. It's easier to correct a slightly under fed plant then a over fed plant.

Always build up, its easier to fix a hungry plant and a toxic plant. Hope this helps 🙂

Always lower let the seedlings get use to the nutrients. If you add to much you will do more damage than to little. Try 1/4 strength and see how they react. The seedlings are small still don't need much.👊
