Can i please get opinions on overall health and foliar damage?

I've been veggin these 5 for about a 50 days on 19/5 lighting with 1 150w hps, 4 23w cfls, and 1 3ft. cfl. I'm using pureblend puregrow 30mL per gallon every 2-3 days. I just got liquid karma and used that as well their last feeding.
I do have a 600w hps on the way, so that will be installed by endweek. (w/ a homemade cooltube).

There seems to be some deficiency with a couple plants, but I'm not sure. Can I please get some opinions from you guys:) . as well as the overall health of them and any tips on what I could do to improve things. oh yeah, and what sex do they look like. :stoned:

I'm pretty sure I saw a pistil in the third pic in the gallery, so I think you have at least one female. I think the plants look really healthy, and I'm not sure what deficiency you think they have.

here is a pic from today

It could be PH spotting if your PH is out of whack. How is your PH and nute levels? Check them first and take corrective action if necessary.

Check out this link. It is a guide to plant problems with pics. Look for the pic that matches your plants and read what it says to do. I checked through it and it looks like either a PH problem or early calcium deficiency.

Is it only one leaf of one plant? Sometimes I get some necrosis on a leaf. I don't worry about it if the plant is healthy overall. I just pull it off.

I don't really see anything wrong with those other than a little heat stress maybe...did you say you were using all kinds of lights. fans?

water is good...doesn't always have to be nutes...water is good. peace
