Clawing Leaves - Dont think it is too much N though..

Hey I have been flowering for 23 days now

I went through a little stage where I had Mg deficiencies caused by too much nutes and not checking pH after adding them, lol. So thats fixed the plant is looking a lot healthier than before, i can actually bend the leaves again without them turning into dust

So anyway here it is

Im using 15-30-15, i flushed it out with water of 6.8 5 days ago, the entire pot was dry as a bone this morning, and I gave it 530 PPMs of nutes, then added baking soda (leave me alone) to raise the Ph back up to 6.8

Now I look at it and it looks like this

claw leaves, could it be too much N?

I dont think so because I have been flushing for the past 9 days pretty much..

Im running a 400 watt HPS, the temp in there is like 25 degrees celsius, growing in soil and yeah like i said shes just getting over a major nute lockout problem humidity is like 35-40

Anything would be cool

oh also, someone mentioned too much pruning cloning..

Yesterday, and yeah again i know its pretty late in flower to do this, but i ripped off a good 15-20 lower really small useless budsites from the bottom, no fan leaves just the budsites

Maybe it is in shock from that, could it be?

too much of something

flush it and give it straight water for a full week then start feeding . btw what 15-30-15 r u using seems 2 me 2 much nitro

Plant prod 15-30-15 flowering nutes

I am gonna go scoop a big bunch of eco bloom ~ 2-30-15 out of my friends tub in a bit, i was just in denial and didnt want to switch the nutes lol

thanks
