Leaves clawing at week 4 of 12/12

My girl hit the 4 week mark yesterday. Looking decent but not nearly as good as some of the stuff I've seen on here. There is some droopage and clawing starting to happen and I'm not sure what the issue is.

Plants are under a 1000w HPS and outdoor from time to time. Temps have been in the high 80s lately. Humidity sits around 25% or so. I water every 3 to 4 days feeding the General Organics Go Box lineup every other water. I gave one final nitrogen feeding on the first week of flower and have only been using flowering nutes since.

You can rule out a nitrogen deficiency because nitrogen is mobile and a deficiency will always start on oldest leaves, not newer stuff at the top. Are you covered on cal/mag either in your soil or water or nutes? That's the most common problem, but it doesn't look like that exactly. So since you switched to flower nutes, it is likely too high in something. Any big numbers in your NPK?

Go Box comes with a bottle of calmag that I use every feeding. Now that I think about it I haven't been following the feeding chart. I've been giving everything besides the Bio Grow. I see that they don't recommend Bio Root or Bio Weed during flowering. Maybe that is my issue there.

I respectfully disagree. The claws are on the lower leaves. The upper leaves are nice and straight. Too much N, I believe is part of the problem.

The upper leaves are a bit discolored though. I’m not sure what that is indicating.

Heat stress maybe? I had a Jilly bean out back in ff soil temps got to high 80's for bout ten days and she started by getting yellowing on all fan leaves while my other strains just thrived. She didn't end well after that.

What is the npk you're using... I would say by the looks of the plants they are not getting enough nitrogen and probably to much phosphate for week four.. ..
