first problem i can't seem to shake

Like a car in a front end collision, these leaves just will not.... fan out. First i thought i gave to much zinc and blocked the iron so I flushed them. Leaves still in that condition i thought i might have over watered and let them dry. When that didn't help, i then started watering, and increased humidity. The main problem may be heat. They are in a western window and it gets up to 95F according to the thermometer even with the window open. Only way in my situation to help this is to block the sun and just use lights all the time. Right now i use all the sun i can and increase the day to 18 hours using a lizard light i got from the pet shop. I am not the kind of guy that goes out and buys special lamps that cost a lot, hell i don't even know where to get them around here. Take a look at my pics and please educate me further, and please tell me if i am wrong in any cause and i'll see if i can change it. Oh, and i'll send pics of some of the others with some other problems, The folding leaves are not root bound i transplanted not that long ago, and i think the one with yellow dying leaves needs nitrogen and the yellow on mother, I use zinc to restore chloraphil, again if i'm wrong on stuff other than my spelling please tell me.

My plants are growing well enough accept all the leaves are like this in the picture. I don't quite understand what is going on. Can somebody help?

first pick is heat stress. Your using the wrong type of lights.

The 4th pic looks normal as long as your getting steady new growth. I usually let those leaves fall off and then start feeding the plant heavier.

the pics in your second post looks like too much Nitrogen. I think I see more than 13 points on the leafs.

I'm using sun light as the majority, but being behind a window, even with it open, in hot days it gets over 90 degrees. So heat stress makes seance. The little guy lost the two bottom setts of leaves. Something that none of the others have done. It might be that when it fell in an accident a while ago the stem had been folded over. I kept it in a strait line but it healed in strands and wouldn't hold any weight. So when i transplanted it, i just sunk the stem in that far so that part is really in the ground. Now it may not have had enough energy to fix these problems and keep all it's leaves, and had to sacrifice the nonessential. I'm sorry, I don't want to sound rude.. I am grateful for your insight and i will be changing the feedings, not much i can do about the heat. Oh, and i highly recommend venetian blinds. they allow some light in, cast shadows that move with the wind like if they were under foliage, control heat a little, allow wind through, and most importantly keep what's on the inside a secret from the outside community. Venetian blinds, just when you were about to throw them out, you find a use for em.
