NEW grower Going good but a couple questions PICS

[Blizzin]

Ok well this is my first grow and I have researched about this for along time now. I am looking for any advice here that I may have forgot? Also I noticed that two leaves from the plant in the back has some yellow spots on it not sure what that is maybe nitrogen defficency which seems like it wouldnt make sense because the others show no signs. Also The two plants on the edge of the reservor are starting to grow at an angle and im wondering if it is that important for it to grow straight. the 4 bigger plants are a little over 3 weeks and the little one is 2 weeks started from seeds. I am noticing slight red on the stem to the fan leaves and read somewhere that are signs of stress? tried to show it in the pic. Any advice would be greatley appreciated thanks all

they look very happy dude so you must be soing something right.

is that a DWC that you have your plants in?

you're gonna have a problem once you begin flowering with the new growth
on the plants that are already bigger blocking out the light for the smaller
plants. thats been my experience with packing them in that closely.

you're gonna like the bud you end up with though

check out my garden for a first time DWC grow using CFL's for light.
