Make sure you stand all the way up at the top. You don't lock out reps 3 and 4 fully. Your hips have to extend all the way.
If your grip is failing, you can switch to a hook grip or mixed grip. But 90 kg is usually a little early to need to do that. I bet you could use double overhand longer if you just put the bar down faster. Let gravity do the 'down' part of the lift. Keep your hands on it, but you don't have to lower it under such careful control.
