This old person recommends you pH your water and use a TDS meter to stick to as a consistent a regiment as possible. I have had the amounts of nutes TDS in RO water be off by 10% or more using the same amount from the same nutrient labels of differing lot numbers, but that was a while ago so maybe it's more consistent these days, but you never know. If your soil is good, you shouldn't need to feed anything for about a month or more of their first weeks of life. I think there are a lot of factors here that can affect this, so give us some more information like what kind of soil you use and your water type and regimen, type of light, and someone can help you.

Use half of what the manufacturer says. Slowly increase it a little at a time if the plants show any deficiency. When I used GH Flora for nutrients, I rarely ever had to use more than 2/3 of what they stated.

Always make sure you pH your water correctly for the medium you're growing in. 6.5 pH for soil.

Thanks your help!End one more question:how many ml/liter call mag can i use??

how many ml/liter call mag can i use??

Since you're using RO water, use the full amount listed on the Cal-Mag. I use very low PPM lake water, and I use 3.95 mL per Gallon of water. For RO, I'd use the full 5 mL/Gallon (5 mL = 1 teaspoon).

Please note that I said Gallon and not Litre. A gallon is 3.89L. Do not confuse the two. If you put 5 mL per Litre, you'll be overdosing the plants.

How much calcium nitrate and Epsom salt would you add to 1 gallon RO water to create a decent cal mag product?
