Hi @Jackhas these burns are PH variations, regulate the pH of all irrigations to 6. Apply less water in each irrigation and let the substrate dry well between each irrigation. good luck mate 🙏👍

A bunch of different leaf symptoms appeared over just a few hours, can you spot the issue in my detailed diaries and solve the mystery?Everything was well, until over just a few hours they developed all kinds of symptoms. I have 2 diaries here for the grow, the 2 called “Grow #2” and I am very detailed about what has been done day to day. So please have a look and see if you know what might be happening

Forgot Worm Castings until 22nd June, implemented with top dressing of Gaia Green Power Bloom and All Purpose. Overwatered at stem for a week or so.

Help Identifying Ailment! BlackBerry Auto on week 6! Nutrient deficiency? Cant find anything online similar.This is my second grow since switching to hydro. Growth has slowed a lot. Leaves are getting brown spots and almost look like they're being eaten but no pests can be found. No root rot, I dont think I'm over watering them. Since I started hydro it's been a real challenge.

Leaf edges a bit yellow and now some yellow mottling. Signs of the same problem?Leaf discoloration now on a few leaves.... Could this be continuing signs of an imbalance caused by switching nutrients for the first week of 12/12? Please see my previous question about yellow leaf edges and Sciolistic_Steve's answer. I'll be switching nutes tomorrow anyway...
