New Grower please take a look

[oneaday]

hi can some one please look at my plants
and tell me if there is anything wrong, i am not sure,
i have 4 bubble gum autos, they are on the 6th wk,
i am using 400 watt hps , cooltube light assy,
i have a filter system , with a carbon fiber filter and fan exhausting clean air out of the tent,
i am using ff ocean forest with a soil ph between 5.9 and 6.7, i water them with 6.5 phd water, the temp in the tent varies from 78 and 81 degrees fah, i am using the ff nutrient trio, grw big, big bloom , and tiger bloom,
i dont know what is causing this, 2 of my plants are real healthy looking big leaves, normal looking,
but my other two plants the leaves kind of thin, spiney,
here are four pictures for you to look at, first two, are the spiney ones, second two are the normal lookin,
could this be just the strain, i also have been spraying the leaves with grow big nutes, please help, thanks

It looks like two phenos to me.
Long Thin leaves = Sativa Dominant
Fat thick leaves = Indica Dominant

The sativaD may finish a little slower, but should be good stuff!

What I heard was that the skinnier the leaf fingers are the more sativa it has, the wider the more indica. I would guess that they're two phenotypes.

Edit: Grey Bear ya beat me to it by a minute!! lol
