MG Deficiency?

Hey all

I have some kind of deficiency that started about 4 weeks into flower. It appears to be MG to me but I'm no expert so here I am. Any ideas? The leaves are curling up and scorched like hell but the plant is still flowering like "normal", that is they continue to grow. Also, it's occuring near the top of the plant, not so much in the middle or bottom. I flushed at week 5 for 2 days, then added nutrients again at 900 ppm. I use a flood and drain system as well. My ph is constantly between 5.7 to 6.1. At one point, it got down to 5.4 which makes me think that caused MG deficiency. Will it be ok until the end of flower or do I need to do something now? I'm currently at week 6. Thanks!

I had the same problem form around the same time on one of my blackjacks... I flushed to remove the mg lockout and started feeding it MagICal... problem stopped.
 
Thanks for the info Reaver. How long did you flush for? I'm not sure if you are in soil or what but for flood and drain, how long?
