I never use FFOF straight.http://www.thcfarmer.com/forums/f57/help-leaves-brownin-yellowing-10461/
Any of you soil guys know the problem?
These were started out in a diff premix soil with low low low amount of nutes but it did have them in it. It was made of peat, perlite, vermic, and "composted forest products" aka wood. So that's why I switched to Fox Farms OF. I even picked up the FF Grow Big but that is looking unnecessary for now. They are the same strain "Karma's Jack"Did you just repot the plant? Or was it started in FF.
Are the other plants that are fine the same strain?
No answers just some ?'s to narrow it down.
Most cal-mag deficiency's have been reported in the 2nd. or 3 week blooming with FF but some farmers are using it everytime they water. 1tsp. to the gallon is what i have read here. I'm using FF and a few days behind you and i have my cal-mag ready even though the shop said i wouldn't need it i see to many farmers here using it.
Seconded. FFOF has NEVER burned one of my plants.
My thoughts exactly. When I put a seedling or clone into the straight ffof, I won't put any nutes to it until it shows signs of needing food. Some take a while some don't.
Congrats on post #50! nice...I asked this question a couple of months ago to hydro shop employees and fellow caregivers and the unanimous answer was No, it will fry the little roots !! The plant may survive but most won't !!
I was told to use Sunshine mix #1 for clones and seedlings then transplant in a few weeks !!

"I never use FFOF straight."
Oh yeah, never straight FFOM soil..you gotta use perilite, ? and other additives ?
