Laughing Buddha/first time growing

So we are in week 4. For this week (or the next 2-3 waterings) we will use plain water just to flush out any nutes building up since we dont do runoffs. Left girl is still strong,as you can see her second node is done and she is building towards the third node. Right one trying to keep up and since we gave her some support she now seems more strong than before. I also noticed a tiny brown spot on one leaf,which makes me worried,maybe it is a calcium deficit. We will see if they need anything,soon we are gonna test our ph in soil and water just to make sure it isnt causing it. If they ph is fine i think imma go ahead and grab a cal mag. Edit: Some days earlier we found 2 bugs munching on one leaf,killed them and now we hope we dont find any of these again. Also the second plant,the droopy one seemed to have loved her support,she can now not only hold herself up but also seems to have bigger leaves then her sister! Currently still feeding with water only and on sunday we will probably attempt topping or fimming since they will probably be building up to their 6th node. They seem fantastic overall,next update coming on sunday.
