Help I can't figure out what is going on. This is my second grow and it's not as bad this time. Last time it started right when I switched to flower. This time it started 3 weeks into flower I have two 600w hps cool tubs in a 4x8 tent. They are in coco with advanced nutrients nuts. I've tried everything. I have a AC in the tent and keep it between 76 and 78. With co2 at 1200ppm my nuts are at 1200ppm I go off advanced nutrients chart. My last plant where a lot bigger and these are a little smaller. I'm thinking now they are getting sunburnt. It's only the top leaves mostly the fan leaves. There is a shorter plant in the corner and it is not bad. I'm going nut trying to figure this out. Can anyone help?View attachment 2891433View attachment 2891434

I always supplement with cal mag and epsom salts, cal mag should be fine, mine are on 4ml per 5l. A bit less that the bottle says.

I use coco so I sprinkle a teaspoon over the top and water through when feeding. Its pure Magnesium, they love it.

Helps if you have Calmag issues as I'm sure Cal Mag solutions are 2/1 cal/mag.

Im using coco too. Should I use cal mag just until lot clears up or every feed? Do u think I should do the Epsom salt too?

I'd deffo use cal mag right through, start on say 2ml per 5 l of water. Use Epsom if you need it later on, the plant will tell you. I do like to use just a touch of epsom right through though that might be my water thats shit

Can anyone help? I'm a first time grower. still working on my setup and am to the point where I am Ready to choose strains. I am seeing that some strains are easy and some are hard to grow. My question is what it it that makes a strain easy or difficult to grow. thinking of starting with Critical kush and Pineapple Chunk. Any advice would be greatly appreciated. Oh, and I'm going to be using soil.
