I guess drdee has the point and itís what I was thinking more or less. Still not sure. Next grow Iím gonna do a comparison grow with one plant I only water from the tab.
Up to now I donít have any further information from our water supplier besides itís hard. But I asked for it. Letís see.
The bottled water I mixed right now has the following minerals:
All in mg/l
I mixed it 2 pt. bottled water/ 1 pt. dilutened water. Will that work out? And other question. Should I add nutrients? Do i need to flush first? Sorry for all the questions guys
Any more than 300 ppm bicarbonates (HCO3) will screw up everything. Blocks all of your calcium by making calcium carbonate.
If you had high ppms in your tap water, chances are it was doing the same thing. This means a lack of Ca not an excess.
It also drives the pH up.
You can acidify your water with some P acid and let it sit a bit, that will burn up some of those bicarbonates.
Much better if you can find some clean water. Can't believe they sell water like that. That water could probably cause stones in the body!
