Advice please? First indoor grow problem

[Paint]

Had to go out of town for a few days and had to leave the babies alone...when I got back I came home to this...

The PH of the solution got just a little high in my absence in the low to mid 7 range but has been corrected, I thought it might be having the lights too close (LED 300w and CFL 256w) within 12 inches from the top of the plants...moved the lights up to about 20 to see if that helps...any more suggestions? I would really like to keep these growing! Thanks!

Ah, those don't look too bad at all - I think you made the right move moving the light up. What are the temps in there?

At the top of the plant, right at 70/72 degrees now that I moved the lights up, before I moved them it was running about 10 degrees higher....

As the pics show, most of the problem are on the older leafs that seem to be catching more of the light. The leafs under the canopy look healthy as can be with no brown on them at all...

what are your low temps at night?

Not sure but they shouldn't run too much cooler than a couple of degrees, my grow area is heated and cooled along the same lines as my wife because she controls the thermostat... lol

I noticed on the affected leafs that in the areas where they were shaded there was very little of the brown discoloring...thats why I thought it might be that the lights were too close for too long...

That looks like a combination of PH stress and Phosphorus def.

Im assuming when you corrected your PH levels you did it in one leap as opposed to slowly lowering it?

I took care of the PH level over the past couple of days going about a 3rd of the way each time...tonight I am noticing that the leafs are not as droopy, kind of perking up! Hoping that the worst is over...thanks!

Anytime man. If you ever have any questions or problems feel free to send them my way either in my journal or PM.

I'd agree with kraw. There is a touch of calmag deficiency too but again prob cause from ph imbalance. Look forward to update!

Going to keep a close eye on the PH for the next few days and see how it goes...Pics soon!

Well then I'll pull up my lazy boy and spark a doob!

yes, looks like phosphorous deficiency which is why I wanted to rule out night temps being too low.
