Hello everyone,

This is my third grow and I have been struggling around with a little problem for the past 3 days or so. Somehow more and more leaves start getting yellow tips and rust spots...

I grow in a coco/soil mix and the plants have been under 240Watt fluorescent lights for the last 4 weeks.
The light is about 40cm away (it was closer during a fast growing spurt a week ago).
Temps around 24 Celcius and Humidity is around 60%.
Runoff ph off 6.4.
They will be moved to a bigger room with 600Watt HPS for flowering soon.
I added AN sensi grow a+b, b-52 and voodoo juice.
Any idea what could be wrong?

If your mixing all your fertilizer together and then putting that mixture into water, that would cause a bunch of your micro's to fall out and become unavailable to your plants. Are you using the old Sensi Series or the new PH Perfect version? That looks like an early boron def or early zinc.

Yes ph perfect and I put one after another into the water.

In that case, I recommend Bills Perfect (Spray N' Grow) Its a zinc + iron foliage spray. Also, even though that Sensi AB says PH perfect, it's not. Monitor your ph.

-EDIT-
So, it turns out the Sensi Grow and Bloom AB PH Perfect does not have many micro nutes in them. In fact according to the U.S. label they look like crap compared to the old stuff. That is how AN gets in your wallet, you have to use the complete lineup of their fertilizer for thing to go right. They even change the formula for bud candy, they took out the sulphur and recommended another product to makeup for it. You can however, get the Micro PH Perfect and use that to fix your problem.

Gawd, I sound like a Advanced Nuterients Customer Support person......... I'm not liking that....

What would you recommend as an alternative? I am not that much into the whole fertilizer thing and AN was the first thing someone mentioned... I never tried something else
