Is this some kind of deficiency? I know the HPS kinda washes out the pictures, but the top fan leaves and the new growth all has this type of lime-green look to them.2011-11-21 23.21.05.jpg2011-11-21 23.21.23.jpg2011-11-21 23.20.53.jpg

What do you guys think? Should I add more nitrogen? It looks kinda like a magnesium deficiency too.

It's tough to tell with that yellow light, but it doesn't look like either deficiency to me ... they look healthy. Young growth will be spring-green, unless you have toxic N levels ... cn

Just checked the pH because I saw some warping of the leaves and it was ~5.0... So I emptied over a gallon of water out and filled it back up with fresh water. pH ~6.1 now. Could I have locked out any nutes? I just check it like a few days ago and it was at 5.8.

I have that chart, thanks though. My question was mainly, would lock out occur in a span of like 3 or 4 days?

Ah, gotcha. Is changing the reservoir to the proper pH all you can really do? I have a reservoir change coming up on Friday so should I just stick to my nute schedule? It's still growing like crazy. Inch per day probably.

Can you take a pic with Hps off so we can see the color of your plant, gives us a better look at , what it might be, from your pics we can't see the color of your plant.

whenever it is a good time for them :)

that way we can see the difference in color ...that we don't see now(they appear fine in those pics) but you will see the difference( if there is) when you take other pics.
