What am I doing wrong?

Honestly, they dont look bad at all. The red stems may be genetics or temps if its not nutes or ph. I had some purple up on me when temps dropped before.

Your first two pictures look like zinc deficiencies...look at the picture below (taken from the FAQ):



Your plants look very similar to that in the first two photos.

Your last photo looks like a pH lockout. 5.5 is pretty low...try to bring it up to maybe 6.0 and look for an improvement.

But, before you go adding zinc or anything to your reservoir...just try adjusting your pH. They should perk up and start looking normal again.

Ok I will let the ph go up a bit. Its the camera that made it look like those pics you have there. Mine are dark green. I was more concerned with the saw blade leaves and the drooping. I fed them earlier with the new nutes ay 745 and my ppm went down. Which is a good sign that they are feeding. Other than the spots on the one plant do you think its a ph issue?

they might be a bit overwatered (upraised edges and droopy leaves). Honestly they look good, really good.

Thanks alot! I have been chasing the whole watering issue for while. Haven't gotten a set schedule yet. Any suggestions?

Well your plants need water while the lights are on so I would say flush the tup right before lights on and again halfway through day cycle.

Do I need to keep my ppm steady through the week by adding nutes? As well as top up the H2o everyday.

If you can add nutes and keep your ph in line then yea sure. I run about 600 PPM

Thanks and i raised my light about a foot. I think it wascontributing to the stress. Thanks guys

Here is a chart I use.

I had a similar problem I believe, with the tips curling up like that. I raised my light and it went away on the new growth and the older leaves that were doing that eventually flattened out.
