It looks like you have pretty well-draining soil. If so then you don't need to worry much about over-watering in that the water will never pool in the soil. You can add more liquid without drowning the roots. (Not quite the same equation as when avoiding damping off with seedlings - there you want the surface dry.)

And yes, it does look like you need some ferts. Go ahead with the MG. (You want an NPK ratio that is some multiple of 3:1:2.)

One thing I notice is that there seems to be a fair amount of shredded wood in your mix (as opposed to bark). As wood decomposes it locks up nitrogen. You could be looking at a chronic problem. What potting mix are you using?

Thanks DM.

I'm using E.B. Stone organic potting soil.
Best I can find around here.

Dave

Not familiar with it. Anyone?

E.B. Stone makes very good product.

Looks like it could use half dose shot of MG AP, Stoney. Maybe a dash of epsom salts dissolved with it, also. No more than a 1/2 tsp/gal. at this point.

Could be a little bit of sunburn though. Take a shaded pic maybe.

Ok Kevin, thanks!

Yeah, EB Stone drains really fast. My Fatali really seems to like it :-)
I'll post a shaded pic tomorrow. I gave it a half dose of MG and Cal-mag today per gallon.
