New grow, plants look sick :(

Your 77 deg temps in rez may be the problem below 70 if you can even if you have to freeze a few bottles of water.

Possibly your pH is high if it's 6.4? Perhaps try 5.5-6.0 could be locking out macro/micros at that level.

Will adjust both of those ty to both of you.

Temp issue fixed, haven't got pH strips or meter, will tomorrow. Got messed up earlier and put my hps bulb in instead of mh bulb I had. Yea I know... anyways, waiting for dark time to switch back out and walk in and bam, new growth under the hps, where they were not doing much lately with the mh. Think I should run the gps a full light cycle (20/4) and see if it jumpstarts the girls(God I hope still to early to sex) into new foliage growth? Not sure if that will hurt or help the problems.

The little one on front right made a whole new set of canopy in like 4 hours under the hps all of them look better already..

HPS from start to finish should be work, I believe that is what uncle ben ran when he grew indoor. I've vegged with four 2700k 38w T8s before and they grew fine despite being on the red side of the spectrum.

Imma give them a cycle or 2 on the hps, that growth, wow, impressed me.

Taking a new pH reading when I get home, will post results and a few updated pictures of the little ones. Since water change and lighting change they are looking better

Water starting off with is 6.6 to 6.8, watering in res is at 6.0

A few pics of the new growth, and new symptoms from today.

Some of the new leaves are cupping downwards, but still show new growth.
I changed the light cycle to 20/4 a few days ago and watering to 1 hour intervals every other hour. Threw in the old hps bulb to see if it made a difference(not really was messed up and not paying attention) and growth exploded. Most noted is the stems, they are twice the size they were 24 hours ago.

Any input to get this back on track is welcomed.
