Could anyone tell me what kind of water to buy? Drinking, Spring? does it matter?
First and foremost...thank you for the replies.
hydr1.....im not quite sure what you mean by ph issues....do you mean my water is fine, and I am just phing the solution too low?
I understand what your chart is telling me, but how dont understand why different nute companies tell you to ph the solution lower (ie canna 5.2-6.2)
Also 5.2 was just a starting point. I fill my rez, which will be full at 30 gals, to about 15 gals. Add nutes, and then add water until my ppm is set, which USUALLY makes my ph about right at 5.2 or so.
The ph slowly rises throughout the week, and I only add ph down, if it gets much about 6.2..and then i only add enough to get it back down to about 5.5
Most recently when I followed the described procedure, my ph was only about 4.4 or so...so i added ph up to get it to 5.1 (thats what i was talking about when i said my well water's ph it seemed to be shifting)
Either way I am planning on doing my next rez change tomorrow, with store bought water (i am getting an ro machine soon), and will add the cal mag you suggested.
Other than that, just add my nutes and ph to about 5.5?
I have also heard to ph the water first, then add nutes, then re- ph? is this true?
what kind of water should i buy? drinking? spring? how soon will i see improvement?
anything else i should do?
thanks so much for the knowledge. knowing is half the battle
Use reverse osmosis water...because your local is unstable. So your starting with water that is stripped of everything and 7.0 ph...0 ppm.
Add nutes...water at 7.0 will prop get you to 5.2 again maybee. Some are against it but I use ph up to bring it to 5.8 or 5.6 and let it swing to 6.0 or 6.2
If you're putting your water through a water softener that uses salt, I would have to say the plants are taking up sodium in place of potassium. K deficency will disrupt many different proccesses in the plant. Try cheap bottled water on one for a week using a high p/k fertilizer. Then you will know. K deficency won't improve on damaged leaves nor will foliar spraying K. Soil drench @5.7-6.2 with a complete fertilizer (any hydro fert).
