I’m running a RDWC system and was told to starry off only using half strength nutrients. Monday I will be water change day and starting the veg nutrients. I’m currently having a calcium Deficiency In one of four plants have increased calmag. When I add the veg nutrients in should I follow the bergmans directions and go full strength or still cut the dose short?

If you are just starting the veg nutrients stay at half strength, at most. Then see how much is left. Depending on size of res, nutes can go quickly

It’s 4 five gallon grow buckets with a 5 gallon res. Now should I use full strength on calmag? I had a calcium deficiency in one plant and boosted the calmag up to 2ml per gallon that only brought my ppm up to 150. I added more today and am around 200 ppm now. For veg it says 3-5 ml per gallon do I stay at half as well or full?

I think 2-3ml per gallon is usually enough if everything else is in line.
