Here we go again Yellow Leaves (Mg? Zinc? or what?)

synmaster · #1 (**permalink**) 11-21-2007, 09:37 AM

So i have been really lucky and this is my firtst problem to date with a grow. I thought i had a green thumb all this time!

so now i have an obvious problem. Plants were doing fine for a week then all of the sudden started to turn lime green from the tops. Now they look like this.

I had my PPM at 1000 and ph around 5.7-6.0

using Veg A+B from Advanced
Hygrozyme
Superthrive
Cal Mag
VoodoJuice

currently i have the 20gal res with just calmag, hygrozyme and superthrive, Ph 6.0 and ppm at 400, hoping to relieve the plants of their stress.

should i just run ph'd water alone? Is it my environment?

please help as this is starting to effect my moms as well.

thanks

yes, looks like iron/zinc def. your ph is ok, so I'd guess that the nutes were too weak, or something is out of balance? I'd just give them nutes and water, without the additives, at stronger ec.
