Your diagnosis please...

11 plants avg 76 degrees F 41 percent humidity under 400w mh
MG 24-8-16 nutes (the last 2 waterings i used just water after i noticed these symptoms) water about every 3 days (i use 1-4 scale water meter)

some plants display no signs and are doing well others have weak tops, some have burned tips and some display discoloration. i believe these are a couple different strains since they were all bagseed. take a look at the pics and let me know what you are thinking.

thanks all!

the discoloration is from heat when they turn that yellowish color and fold in like that nothing to worry. you go t a fan.. the tips no biggy it could of been it just got too hot for a sec in there.. but blow a fan at the light this will help the light from burning ur plants

do you think i should water less often, or do you think i am giving to much at one time?

one of the plants looked a little over watered. The one with slightly clawing leaves. They look fine overall though.

I didn't know Tom from Myspace grows!!

really u should water only when the pot is as light as air this will make your roots strech for water and make them nice and strong. amount of water just enough untill it seeps out the bottom then u will see the leaves perk up a lot more... but overall they look good...

I used some mir-gro and mixed it with some of my water and the ph went way down. I had to use some ph up to get it back around 6-6.5. Have you ph'd your soil? Your plants look like min when I screwed up the ph in the begning of my grow....

i just PHed the soil and it's all coming in at 6 - 6.5 a little low but just barely. i attribute some of that to using unfiltered tap water but at least i let it sit out for a day or 2 before the plants get it so the chlorine is down. i think it has a lot of calcium in it though. I'll stretch out my watering scheduele and see how it goes. thanks for all of your advice!

so i just waited 6 days in between waterings. does that sound right? they werent drooping or anything but the pots were getting pretty light
