MY FIRST GROW WITH 21ST CENTURY TECH

Week 5 was defiantly the toughest yet didn't think I was going to make it to the end of the week, but here we are about to bump into wk 6, at the beginning of the week I notice some sort of deficiency on 2 leaves, 24 hrs later 2 plants were 75% dead and the rest was looking droopy, with a bit of helpful advice from @harbingerofharvests I was advised I was suffering from "Lock out" performed a "RO" on all the plants 24hrs later the recovery was amazing, another 24hrs have passed and you would not think there had been a issue... Really appreciate all this advice coming from @growdiaries 👌🏿😁🙏🏿
