I am using the Cal Mag, i even started giving 8-10ml rather than the suggested 5ml at the first sign of yellowing, and its my understanding that Organics dont have the salts that chems do so it cant be that, right?
Right the imbalance can be caused by your water, is it well, tap?
yes it could be. calmag is probably not organic but thats irrelevant. you dont need calmag very often unless you use RO water. If anything add more grow cause it contains the most N. that food is not like most "organics" it is already broken down and ready to eat by the roots. so IF it is a N def then it will correct itself quick with your pureblend grow.
Yes the bottom leaves are pale yellow that still remain, the others have crisped and fallen. And yeah i figured it would help so I doubled on the Cal which still contains Iron EDTA. Is the EDTA a problem? Could my ph be that off in soil when I water with bottled drinking water only(6.2-6.
, no R/O or distilled....Neither, I only use drinkin water, ph'd of course.
I do feed with every watering, I have been giving the Pro grow, the yellowing began right before I switched to 12/12 and has been working its way up. but yeah I havent stopped doing that, but i know that eventually in order to bud I will need more P...which means more Bloom. Ive never posted a pic, never needed to, but maybe my time has come.... when you see it you will probably say its not bad but im not used to having nothin less luscious green, lol.yes it could be. calmag is probably not organic but thats irrelevant. you dont need calmag very often unless you use RO water.

If I was to use any line of nutes, I would have continued to use a typical grow formula until third week into flowering. Something you should consider on the next cycle.Im beginning my second week of 12/12 and having a major N deficiency. Im pretty sure thats what it is, so no need for pics. Also im using Botanicare products. Pure Pro 3-2-4 , Pure Bloom 1-4-5 ,Cal Mag 2-0-0, Liquid Karma .1-.1-.5 and Sweet 0-0-0. Somebody pls help!!!!oh im in FF soil by the way...
tHANKS A MILLION TIMES OVER FOR ALL THE HELP YOU HAVE PROVIDED SO FAR!!!back off the cal mag completely for at least 5 or 6 more waterins. how far along are they ? you proly dont need pics , you seem to be on it. most folks would be screamin "nute burn" ....
make sure an use full doses of the karma, its good shit.
as long as you are 100% sure your not overwatering or way over feeding then i believe the extra cal could help to slow down the uptake of the N.
if your only a couple weeks or less then keep the veg food goin and slowly incorporate the extra P.
