Why are my girls sad?

[Widowmaker]

My little white widows are all showing signs of sadness. In the pics, you will notice that the edge of the leaves are yellow. This has been going on for a week now. They are 17 days old. For the past ten days they have been in the drip system on a half strength Ionic growth and boost solution. They are under a 250 HPS with 2 40watt FL on opposing corners. The temp stays between 80 and 83 with the occassional drop in temp when I open the door. The humidity stays between 20 and 30, mostly towards 20. They get CO2 four times daily.

Why are they upset? I've heard that it could be nute burn, or lack of humidity. I tried putting a humidifier in with them but it never got the humidity over 27%.

I'm a nube. Law school takes all my money so I need to grow my own. If I don't succeed in this, I might have to quit smoking. That can't lead anywhere good.

Your help is GREATLY appreciated.

Thanks,
Widowmaker

Pro,
I'm putting them under a 400watt hps tonight. I ordered a 800watt dual HPS and MH system. It should be here next week. I'm wondering when I should begin to give them nutes again. Should I start them on a half solution again? I was thinking two more weeks under the 400 with a half solution starting later this week. Then switch to the 800 dual, full strength solution and constant CO2 enrichment. Sound good? 30 days of that?

Thanks,
Widow
