Well the first to weeks of vegetation I only use 5-ml per gallon but after that I bump it up to 10-ml per gallon. I assume you can OD on CalMag but you never use more then 10-ml per gallon. Itâ??s not part of the NPK fertilizer we use a base nutrient formula.

Silica Blast is different and another type of supplement itâ??s potassium silicate and will strengthen your plant's girth increasing cell wall.

Well the TDS is for the overall NPK measurement. The way I deal with nutrients is like this,

30 gallon reservoir I only fill it with 15-gallons RO water to start for 40 plants.

Then I add the Micro first (the one for RO water, there is a difference) Micro is the most likely to lock up on the plant and you want to make sure it gets mixed well.

Next I add the Grow formula and then mix again for about a full minuet.

Last is the Bloom and then again mix for about another full minuet.

Let it set for 5 minuets and give the buffers a chance to Ph the water for you so you donâ??t play the Ph up and down game.

Now you check the TDS, the chart you are using is only for those 3 nutrients.
The others stuff are enhancers so that makes it extra. Most of the labels say how much they will raise the TDS.
I donâ??t subtract it from my NPK mix at all I just Ph balance and then let it sit for another 5 min (or smoke a J, same thing)

Now I add the
B1 5-ml per gallon
H²O² 5-ml per gallon
CalMag Plus 5-10-ml per gallon

Bloom enhancers are last because they mix easy and dissolve fast. I follow the directions on the bottle. Iâ??m trying 2 new ones right now and they very in how you use them. I know a lot of people like to use only ½ strength nutrients and that puzzles me. If you use the proper nutrients at the proper cycle in the plants life you grow huge stress free plants.

Ph is important to always keep an eye on at all times if you can. The Ph chart in the FAQ gives you a good idea of how Ph affects what the plant can absorbs at what Ph. That information is used to help concentrate the proper nutrients at the proper cycle sometime you need to run your Ph at 6.2 to correct a problem for a few dayâ??s then take it back down to 5.2-5.5.

If you watch your plant closely you will know the cycle and when to raise or lower the Ph and when to change nutrients and bump them up to the next level. They go through growth stints just like children do and sometime they can use more and grow faster and sometime they donâ??t.

Once you start seeing the pattern it will make sense. It took me many years of growing to get that serious about this plant but it does payoff.

Did that help or did I get off topic? Anyway it was interesting and thought you would like it.
Zandor Reviewed by Zandor on . Hey Zandor........ How much Cal-mag do you add to supplement your hydro grow? Bottle says 5-10 ml. per gallon of reservoir. I've been adding a bit less than that in fear of over-nute. I have a few older leaves on only two plants that are a bit yellowing but with some necrotic spots and patches. It looks kinda like the pic and description of Mg deficiency or Potassium deficiency. PLants are only at three weeks veg so I don't want to overload them. WOuld Silica Blast (Potassium Silicate) help if it was an Rating: 5
