Nitro toxic?

Sounds about right for the feed. I've not come across the DN line before but that still sounds a little low to me for cal-mag. Most coco users will be looking at about 2ml per litre.
PPMs sound about right and the plants look good to me. Looks like you'll be fine from now on.

No, you shouldn't be feeding full strength. Autos usually don't like it and the addition of the soil will be providing some nutrition anyway. 50-70% would probably suffice, but the plants will be quick to let you know.

AN is very expensive and you won't see much love for them around here. There are much cheaper out there that do just as good, if not better. Lots of people are into Mega Crop, I've not used it but seen great results and it's very affordable. General Hydro are pretty good too but require some additions at flower.

Your plants are looking great, I wouldnt lose too much sleep over it, you'll be fine, keep it up!

:peace:

I'm just in my first grow - almost finished - and my research led me to Megacrop. I think it has performed fantastically, and that the CalMag issues I am having now are because of my use of Ocean Forest soil - which I won't be doing again. I highly recommend Megacrop and Bud Explosion.
 
well i ended up flushing my girls out for about a week, maybe two?
then just swapped to blooming food anyway 1/4 feed when they started to show some yellow
they seemed to be doing just fine, think i got some phosphorous def in one, and had to up the food on another one, some high maintenance bitches it seems
so not sure if it was nitro toxic or not, but it seemed to work out for me, they are still alive, although kind of all over the place

been awhile, i gave these bitches a flush for a week or two going into flower, then switched to bloom nutes when i saw a little bit of yellowing
upped the PH to about 6.0-6.2 as i found out im in about 60/40 coco to soil
dif feeds for these ladies now, think i solved the nitro toxic, as i was feeding a little low in the ph range thinking i was in just coco (explains why i only have to water every 4 days or so)
now maybe got phosphorous excess in one, and underfeeding another, i dunno they finicky
but no more nitro toxic!
