I don't know whats wrong with these plants!!

This grow has been going great. I took these cutting about 8-9 weeks ago. I had them under metal hilide and they grew so fast and hardy (my best grow from cuts by far, 1st time with metal hilide. THE LIGHT WORKS GREAT BTW. Then I put them under a HPS light and put them into flower. I put them into transition phase on my feeding chart. I was using the GH 3 part system, but recently I switched to the Maxi Series by GH (the powder) OH, I flushed them for a few days by accedent before I put them into flower (I got real stoned went out to change my nutes, filled the resivores with water and forgot to put nutes but thought i did. I'm usually pretty good at this, but I need some advice on this one, I am stumped. my leaves look droopy and the tips of the fingers are curling but they arent turning color at all. one plant is about to get yanked out if it doesn't start acting right real soon. i have 2 replacements under MH. Oh and I gave them some B-1, because I took cuttings before i put them into flower (just remembered that) do i need to flush? Any advice would be greatful. this site got me pretty far when i first got started.

My guess is the humidity went from around 65-75% down to 35-45 %. Bring up the humidity and that may solve your issue.

Youre right Humitity did drop from 60 to 30. I do that usually. never had a problem before. I will try that. but when buds start coming I have to drop it again. should I drop it slowly?

I went back out there, and there is brown showing on the leaves. could it be lockout? What should I do? Should I post more pics?

What you need to now is try not to over think things. Simply put, your ph is too low for the time being. Just raise it and then wait 2-3 days for a verified response. Don't go flushing, shuting lights off or anyting except normal routine. It's amazing how fast they actually bounce back.

I Just read you coment about SLH. I just got done with a run of SLH. It is everything everyone says. It really does smell and taste like lemon heads.

This is a month later. I forgot to come back and tell you that this ended up being heat stress. Three plants in this crop died. When I brought my humitity up it made it worse. I don't know how I overlooked heat. I could feel it but my Temp was 75. It was stuck on 75. Humitity was stuck on 30 so I raised it HIGH before I realized what was wrong. This crop was PERFECT (The best I did) when it came to cloning them, and veging them. But when I went to flower them I killed them with heat and humitity. I saved some of the plants, but they still won't make me happy with their yields. My rooms are like plastic huts in my garage and I was running my lights during the day with a small air conditioner. To fix the problem, I bought anouther fan from home depot to help blow the cold air around better and reduce humitity. Replaced the dying plants with some mothers I kept (took plenty of cuttings to keep the strain and start anouther crop) THE CHANGE THAT HELPED THE MOST: I changed my light cycle from 9am-9pm to 6pm-6am. That change helped the most! just checked it 75 degrese. Humitity 35. My strain is the BEST Ive flowered. to people that read this CHECK OUT SUPER SKUNK FROM SENSI SEEDS. FAT YIELDS. FINISHES IN 45 DAYS. TASTY, POTANT BUDS. Just wanting to share some info.
