Hello All,
A lot of you may have spotted my enthusiasm around here to grow a small amount of the great herb in my growcabinet.

I always seem to have this problem. I'll veg for 6 weeks or so in my 7.5 litre pots, using biobizz All-Mix, no problems, PH stable between 6.2 and 6.8 - thanks to my 1litre Nitric Acid bottle PH adjuster. I know it isn't particularly recommended to use a Nitric Acid in a non hydro medium, but I use very small amounts, perhaps 1 ampule NitricAcid, per litre. This maintains a PH of 6.2 to 6.8.

but, the problems start a few weeks into flower...

Even when I do this PH adjustment, I find that the plants just lock out, the same happened when I wasn't using Nitric Acid. I've tried flushing for a week, I've tried a half strength and quarter strength feed over a week. Nothing seems to make these plants happy. This is interesting because the leaves appear to be very dark green, and curl as if they are overferted, even though PH and nutrients are at very low levels. I'm running out of leaves!! Sooooo.. what is it? It's the damned water is what it is.



HERE IS THE THEORY! The water here is VERY VERY HARD. I mean limescale build up can be measured in weeks and months, not years. I think I understand what is happening in my soil. I'm getting a buildup of unuseful `limestone` which is locking out and taking up the sites for nutrient transfer of other compounds, namely Nitrogen in this case.

Is there anything I can do to this hard water to remove the limescale causing components? It shouldn't be that difficult, quite easy, but I am definately positive this is the problem. I have a fair bit of experience as a technical type, and hope someone with more experience might be able to guide me.

I'm using biobizz Bloom (1ml or 2ml to 5ml /litre where 2ml is half strength), but that doesn't matter. I'm sure if I used a nutrient that had extra buffers for hard water I wouldn't be having this problem.

I'm sure this is a lot of peoples problem, but because of the technicality of the topic, so many people think that they can do nothing; that doesn't seem to be the case I could treat the water with a buffer, I could remove these compounds maybe or could find a bloom fert specifically for hard water.


Somebody help me out here!!? I think there should be a sticky on this matter, any takers?

Thanking you guys in advance,
Peace,
Denial
