Back for more assistance

[A4]

Once again, I seem to have effed something up. Last week I had a few lower leaves that were yellowing due to ph being out of whack. I flushed with tap water, ph'd to 6.5. I refed at half strength and everything seemed to be fine. This morning I took them out to feed and now I have yellowing on the top leaves, mainly on the inside though. After researching for about an hour I think this may be sulfur deficiency but I am wondering why it is only affecting the leaves on the inside of the plant?

My setup is 4x4x6 tent.
Pro mix BX in5 gallon smart pots
600W Hortilux HPS
Temps are ~80 during day ~70 at night.
PH at last feeding was 6.3 in 6.1 runoff.
Circulating fan at tops of plants and inline fan pulling fresh air in tent with all vents on bottom open.
Filtered tap water with GH Grow 1ml, Bloom 2ml and Micro 1ml and Magi-Cal 5ml per gallon.

Thanks in advance again for any assistance. I have learned one important thing during this grow, growing weed indoors is definitely more challenging than growing vegetables outdoors. Much respect to all of you old hands! This ain't easy.

http://www.growweedeasy.com/marijuana-symptoms Check this thread out.They are pretty far along in there problems,but I would up the dosage of all your nutes and cal-mag.Looks like they need NPK in larger doses.Also I would go 10ml per gal of cal-mag.They are in rough shape so I hope this helps with them in there condition.

Thanks Nam, I was waiting for someone to answer before I fed them, do you think a full dose is appropriate?

I would try the full recommended dose .I just hope there not to far gone.It can;t hurt to try.If you need help again don't wait so long,it's better to catch it earlier than later.
