Someone tell me what my problem is *pic*

Not sure what the problem is, i'm thinking some kind of deficiency but figured i'd let the experts take a look.

Plant is about a month into veg, DWC setup using Foxfarms nutes. Daytime temps hit mid 70's and dip into the lower 60's at night. Plenty of airflow and she's under ~150 watts of CFL. Roots look extremely healthy. I was out of town had someone feeding and adding water while i was gone, I gave them a modest feeding scheduale just to be safe. I know i need a ppm meter but for now i've just got to wing it. The Ph could have very well been out of whack for a few days while the person was taking care of it. I had them adjusting it but i wouldn't be surprised if she forgot or overdid it with the up or down.

Let me know what you think here she is.

could be ph problems. what is it at right now?

it's at 6 right now, new growth looks good though, the Ph may well have been out of whack at the time those leaves where new. But shouldn't they have cleared up by now? They're a good 3-4 nodes down.

looks a lil nute burned to me.

it will do its thing in time. you might want to bring the ph to 5.8. honestly, i'm a soil grower but my friend who grows hydros keep his at 5.8 and his ladies look healthy. sorry couldn't help more...

you had someone else feeding it? i get a feeling that you got some nuet burn goin on, if the new growth is good i would just get your ph up a little and call it good, assuming the problem hasnt gotten worst since you got back... if it has i would flush it

Well i have a 40 gallon res, and im adding about a tablespoon every 3 days, and about 3/4 a gallon of water everyday. How often do you need to add nutes and how much to keep your ppm stable, roughly i really have no idea. From what i've seen the leaves will get dark green the more nutes they get untill they burn. Mine are a pretty light green, I'm sure thats a poor indicator but is it usually the norm?

Thanks for the input guys, i really appreciate it.

you need to get yourself a ppm meter and do a check.it will probably solve your problems...good luck

I'm definitely going to be ordering a ppm meter soon. For now i think i'm going to go ahead and change the water in my res and see what happens, I'm not terribly worried despite some leaves looking that way the plant seems plenty healthy. It just feels like its not getting any better or worse i figured the plant would easily fix it's leaves once conditions returned to normal.

Again, thanks for the help everyone. May all your buds be all the fatter for it!

flush flush flush use ph adjusted water 6.2 if its a minor deficiency nute burn most likelky... yes a ppm/ ec meter will help you control your water levels.

For reference i figured out the problem was wild Ph spike, happened to me again after flushing my res, if i don't adjust the ph every 4 hours or so for the first few days after changing the water it'll go seriously alkaline. But she's all good now and looking mighty healthy. Thanks for the input everyone.
