2nd attempt, day 15

[Mole2k4]

Hey guys,
Growing my second batch of plants now.
(10 skunk haze, 10 jack horror and 2 feminized neville's haze 8 never sprouted )

problem is, some of my plants aren't looking great.
Day 15 now since planting, in comparison to my last attempt, they are further developed, and while they initially started stretching, there is virtually no space between the leaves, unlike my last attempt.

Enclosed is 3 pics, 2 of 1 plant and 1 of another.
These are the worst plants I have, some are perfectly fine and looking great, and some have leaves that are virtually closed upwards.

In this attempt, I'm using a different potting soil, so am guessing that is why.
Anyone have any ideas? I'm using my 400w HPS and its between 1-1.5 feet away from my plants, there is a circulating fan on them, to help the stem and its circulating to prevent wind burn and heat burn from the lamp.

dont use the hps this early on man those plants dont look healthy
invest in some cool white flouro tubes like 4 double 40 watts should do it start using the hps when ur flowering.
peace

perhaps this is the reason, i started them off on a 100w fluro light, thought it was time to change when they were still stretching.
