stinkyattic,

Thanks for the advice - I had avoided tap water because the water here is extremely hard and I was concerned about excessive Ca++ and Mg++. I have a softener but then the water would be Na+ laden. I'm thinking that I may start using a 50/50 blend of tap and distilled - or just stick with the distilled and add the CalMag plus.

Regardless, as per your advice (and weedhound's) I'm ordering new nutes now (will try the Canna Aqua A+B).

I'll post picks of the progress -- thanks again!
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
