Plant problem

[Weedhound]

Interestingly.....according to my hydro man.....its VERY hard to OD on CalMag. If your leaves are going all dark and curly that just plain sounds like overnute to me. I sat down the other day and had a fair discussion on the use of CalMag with my hydro guy.....i'll be using it MORE these days instead of less. Just a thought I'm tossing in.....

Not quite sure of what it had too much of but the flushing seems to be working
In your calmag nute what is the ratio of Ca & Mg?
Does soft tap water generally have more Ca or Mg?

[Weedhound]

Soft water generally has less of both. The only real way to know exactly what is in your water is to have it tested.

When you see your plants startng to look burned you might just try lowering your e.c. instead of picking one nute or mineral and thinking that caused the problem. Just lower your entire e.c. and see it helps.

Another thought and forgive me if this sounds harsh......it seems to me that when you've improvised things its gotten you into trouble. (rainwater etc....) If I were you, I would look at the directions printed on the back of your bottle and stick to them.....although using nutes at the same ratio but less total e.c. usually works best imo.

Think about this: 1. You just paid good money for those nutes. Wouldn't it be wise to use them the correct way?

2. Who wants you to get the best out of their product? The people who made it. So it makes sense that they are going to tell you the best way to use it. (see.....they want you to buy their product again......)

I strongly suggest you try NOT adding your own ideas here and see if that works.

Good luck.

Again....apologies if that sounds harsh but your "improvements" here just aren't working.

Thank for the input but I sorry to disagre but logic tells me otherwise.
The manufactures make nute solutions for both soft & hard water.
By doing this they must find the average disolved salt levels for both soft and hard waters and then make thier formulas to suit the average soft water and hard water.
Therfore I took what I consider to be an average soft water salt level for soft water to be about EC.0.4-0.5
Therefore I took my EC. 0.1 water and added Ca & Mg In equal parts until an EC of 0.4-0.5 is atained.
I have written to canna and GHE on the subject.
We shall see what they have to say.:thumbsup:

My last comment......your first grow.....these folks have been making this stuff for years (and testing, tweaking etc....) Who am I going to believe......logically?

Have a good grow.

If i have to eat my words thats no problem....
But I'm looking forward to hearing from canna & General Hydro
