I would go even higher with that humidity. At this stage in growth I would like to see my VPD between 0.80 & 1.00. At 29°C that would be between 70 & 75% humidity. Here's a chart, until I started using sensors this was my goto chart. 
Thankyou. I'll ramp the humidity up abit more then. I'm hoping the temps will drop a little and that's why I didn't have it as high. I think the increase in humidity has already helped
