I offered before in the Reconstituters thread to send you a batch of my Trace + Iron if you wanted to try it out. Offer still stands.
That would be great. I'd certainly be happy to pay my way, I want to get on this urea dosing ASAP really.I got mine from eBay.
Nickel(II)-sulfat NICKEL (II) SULFATE HEXAHYDRATE 99,9+%- 250 grams
If you have any difficulty getting it I could spare a little (you don't need much, 100g is what I got and that's still a lifetime supply).
There seems to be a big shortcut there which made me consider if I was saine for a good part of the evening . Then I read your thread several times and noticed I had missed this:Add to 100ml RO/DI 1.13g of NiSO4.6H2O then dose into your ferts mix at 1ml/500ml giving you 0.0005mg/L in the bottle.
Adding 1.13g of NiSO4.6H2O to your 100ml bottle makes that solution 2,523.2 mg/L (ppm). Then adding 1 ml of that solution to your 500 ml fertilizing bottle gives you 5.0456 mg/L (ppm). Further dilution of 1ml of that 500 ml to 10 L of water will gives you the targeted 0.0005456 mg/l (ppm).I missed a bit ^ I should have added that dosing the resultant mix at 1ml/10L gives 0.0005mg/L in the tank.
