I'm happy I remembered to annotate those oxidation states correctly and didn't embarrass myself! I went medical but each of those ions are still a part of my working life - though I can't pretend to even swim in the same sea as an analytical chemist. (Although I dabbled in some research in the NMR spectroscopy part of your field for a little while.....)

PS: The Canna nutes are ordered and on the way!
cosmas Reviewed by cosmas on . Help! I'm almost out of weed and the leaves on my resupply grow look like this! I've had this problem since nearly the beginning of the grow and can't seem to get it worked out - I'm in week 5-6 of veg and it's getting worse. Lower leaves seem to be more affected than upper. I'm growing white widow from seed in a dwc/bubbler setup (good airstones and pumps) 1.5 " rockwool cubes (now dry) in meshpots with clay pellets Distilled water, changed every 1-2 weeks, nutes at 500 ppm temps max at low-mid 80s daytime and min in the high 60s-70ish at nighttime. 230 watt HPS Rating: 5
