So I'm 3 1/2 weeks into veg. w/ clones from a local dispensary. I'm running Purple Kush in 6" Grodan rockwool's in an ebb and flow system w/ 40 gallon rez and 1000 watt HPS 3 ft. from the top of the canopy. I'm using RO water w/ GH 3 part mix at 3/4 strength, CalMag at 1 tsp. per gallon, and 1 shot of Super Thrive. Just a couple days ago I noticed a few fan leaves 3 middle fingers starting to droop and claw. They are now progressing to a light green/yellow and develop a few dark spots. I'm going to flush with ph'd RO water tonight, but I'm a little clueless as to what I should do next and I'm not sure why I'm getting this problem? Oh and my current PPM's are at about 1800. Any help would be highly appreciated as I wanted to switch my lights within the next few days and I want to stop this problem before it gets bad. I tried to take pics but the HPS light leaves a grid of black lines on my iPhone and it's useless to look at. Thanks in advance!
PLEASE HELP! Fan leaves are clawing and turning yellow.

plants just start to turn yellow during flowering, its probably nothing to worry about
Thanks for the quick responses! @ mistaphuck I didn't switch over to 12/12 yet so I think it's a deficiency. @ Grizzdude so you think I should just add more Gro or Micro? Also on the plant that has it the worst I noticed the new shoot growing from the top is light green/yellowish unlike all the other plants. I'm going to flush tonight as soon as my RO water is ready, should I flush for a couple days to make sure there isn't salt build up in the rockwool? I'm planning to switch to 12/12 early next week cuz my plants are already at 11"-14", but I don't want to switch with stressed plants.
Can't get any clear pics with my iPhone cuz the HPS leaves a black grid on the pics. You think it could be nute burn? I don't have any burnt tips on any leaves on any plants though? On the very few leaves that are clawing and turning yellow there is like 1 very small rust spot. I'm using GH's feeding schedule at 3/4 strengths should I kick down the
dose after I flush?
dose after I flush?

try turning off the HPS and usin a flashlight. btw, with most gps enabled phones nowadays(i know for a fact the iphone does), all ur pics have the location where u took it in the file. so ppl can find out what ur address is just from the pics. i took a video of my plants on my phone once and uploaded it to youtube, and it had a bigass google map showing where my house is haha.
just fyi
Alright I did a rez flush until there was only around 100 ppm in the runoff water of my rockwool's. Then made a fresh rez at 3/4 strength. The leaves that were clawed are now progressing to turn more yellow and the dark spots became more apparent rust spots. Trying to get some pics up, but the wifey's camera is broken so I need to borrow one before I can post some up. Somebody help a brotha out!

You ever get this fixed....dude...all your levels are off....PH needs to be 6.5-7.0 or as close as possible...1100ppm is what you should aim for...what medium you using....is it just in the rockwool...maaan...throw then puppies in some soil or sumthin...if the new growth starts to look good and the old leaves aren't recovering...snip,snip...cut thier ass off like a criminalized republican....Their are so many variables that with out pics its hard to say...but try and fix those levels for start...whats your temp like.....Flushing should always be a LAST RESORT bruh....Good luck man...and if worst comes to worst...make a clone from them....if you haven't already...I ALWAYS make a clone of EVERY plant..and just keep the best one as the mother.
