m0useanswered grow question 3 years ago It does look like it.
also good work on keeping it happy for a 6day vacation break.
Given that it is an auto it will need less feed like you have been giving it. props to you.
Maybe it would like a tiny bit less on top of that. Could always push ec back to .7 or .8 for a week till it grows a bit bigger.
Is your run off EC good??
This is the reference point i use for auto feeding. its not 100% so if they need more or less you just have to adapt your feeding schedule to it.

You are right on par with i at .9 for repeating weeks in veg.
One thing I have noticed is that when I let my plants dry out more they tend to show more issues, this may go away not that your back and watering regularly.
I'd play it safe and down the EC by a point for a week then work my way back up.
Best Of Luck!
