First Grow - Triple Automatic: Purple Haze, Apple Fritter, Purple CousKush

Week 4 day 1. Plants seem to be doing good. Purple Haze has a yellow leaf tip, I can only guess it's from making contact with the pot all the time. Since it's my first grow I'm uncertain if I should try LST, or go completely without stress to learn what and see what yield and quality I get without, so I can compare it to different methods of training in later grows. Just yesterday I gave em each around 600ml of water with Plagron Power Roots after 10 days of not watering! They didn't show signs of underwatering yet but I felt it was a good time. Update Day 26: Getting bigger and more beautiful every day. I defoliated 1-2 of the lower leafs on each plant to ensure airflow. Have a bit high humidity (65%ish) due to the weather outside (rainy and humid), fan and vent on full power. Apple Fritter surpassed the others in size, Purple CousKush is a bit behind. 2 Days ago I watered them with a bit of Power roots and half of recommended Plagron Bloom in 600ml water for each plant (was probably wrong since they aren't blooming yet...), but no signs of nutrient burn or anything so far.
