White widow kalashnikov

So i went for quick vacation/holidays to Georgia (love it!) and asked a friend of mine that lives nearby to take care of me babies 😊 so he watered the girls every 3,5 days on average (4 times during 14 days) with just as little as 100 ml per plant. Now I come back yesterday and I’m very happy with my girls - they look super thriving and eager to grow! I’m surprised as so very different they look from my previous grow in same setup except hydroponics - this time in soil in same day of vegetation they look much more dense and just thriving! Wow soil makes huge difference indoors. I saw 2 top leaves (on pictures & on video) with light nutrients burn (no idea why - I just added root juice). Also I know for sure that my light timer has broken - there were days when light was 24h on...I don’t know what might that cause... but now is all good - light timer fixed. I think that I will just keep feeding them water. What do you think guys? Would love some advice! Oh and pictures and videos are from yesterday. Before topping and after topping. On 2 girls I have used new topping technique. Thanks!
