Eel's 1st indoor grow- Meph White Crack

Week 4 update: So... alot has happened this week. Recap: Day 22-24: continuing LST, thought I noticed the start of some nute burn on one of my other plants, so decided to feed only calmag+rhizo+regulator PH'd to 6.3 Day 24-25: After feeding them and doing some defoliation I went to check on them 7 hours later and noticed the further most hook to keep the top down on WC #3 had come lose. I was readjusting it when disaster struck! I forgot to support the plant further down(by the next hook) while pushing down and snapped the top clean off.... brought my mood right down... but my god it's my first grow and using LST so I'm just gona learn from that mistake. Day 25-27: continued LST albeit with much caution. on Day 27 I fed them again without any added veg nutes again. I also did some defoliation and noticed what seem to be small bite marks on some leaves... I look all over and under for signs of bugs but couldn't find anything. They are also really showing signs of going intoflowering on day 27. I also noticed what seems to be N toxicity(only the CalMg has a tiny bit of N that I've been feeding this week)so looks like I'll be feeding them only a tiny bit of PK booster with less regulator than usual. Day 28: First big noticable stretch of them starting to flower. Really looking forward to the next 6 weeks :D
