Leaf problem,

Hey guys,

First time grower in my wardrobe at home. Got some Fourway seeds from a friend

I'm running 4x 18w 2ft growlux 1350Lumen cool white tubes
Growing in 100% soil, although I'll be repotting when the time is right with a better mix (more research and sourcing to do).

I've been adding a 20:20:20 nutrient compound, but mixed a little too strong as the pictures show, so I'm holding back for a while.

The problem is on my top leaf, near the stem it seems to be falling away. I've checked for bugs and it all seems clear. I have been hunting around town for some litmus paper to no avail, and I don't have the funds for any soil testing equipment, so it could be a PH problem that I can't diagnose.

The squiffy plant is confusing me too. I foolishly started out with a mega 500W scorcher of a halogen which buggered the little one completely. It's just clawing itself back and has done some mega growing, albeit in a wierd shape. Any ideas?

Cheers for your help guys.
