Need help diagnosing leaves, pics included.

I'm trying a SOG grow in a 2x4 flood table. Everything is looking pretty good so far except for a few funky looking leaves. Hopefully you guys can help me diagnose them.

Some info on the grow: The strains are Bubba kush, bubblegum, and master kush. Using tap water that comes out a 500ppm (San Diego), adding Botanicare Pure Blend Bloom at 1400ppm (just started adding liquid karma too), adding 29% H2O2 at 3 ml/gal every 4-5 days, temp and humidity are usually pretty good - sometimes it gets into the low 80's. I was flooding twice a day for about 8 minutes from start to finish, but I just switched to once a day. The medium is Sure to Grow loose fill, which is non wicking, but holds water pretty well.

Pic 1: A lot of the lower leaves on my plants are starting to look like this. Some kind of deficiency?

Pic 2: Leaf twisting and purple stems - I was told the purpling was from too much phosphorus but I've read its from not enough.

Pic 3: Leaf curling. :confused:

Pic 4: Leaf tips curling down

Pic 5: Does this plant look like its stretching?

Thanks those sites seem pretty useful. I still have no idea what's wrong with the leaf in the first picture though, it doesn't seem to match any of the deficiency pictures. Also, I don't know how my purple stems could be from a phosphorus deficiency since I'm using flowering nutes at 1400ppm. Still confused about the twisting, curling leaves - could that be a combo of cal/mag deficiency? Lastly, does anyone think the plant in the last pic is stretching? Thanks for any help you can offer.
