Diagnosis of stunted plant, help please!

Hi

Any updates? I'd be interested to see how your plants are doing now.
I had the same problem with my 1st grow, stunted plants, turned up leaves with yellowing etc and it turned out to be a combination of over watering and heat stress. Anyways, it's all sorted out now, hope you're plants are rocking...

Peace,

The little cups look maybe root bound the bigger plants could be feed? I dont know if thats it but thats why I'm not going to grow in dirt again? To many variables the ph is harder to control. Then every batch is different. I think they changed ffof I give up on it. Going to go with all rock wool so the problem is high ph with rock wool so if it gets high I can put some ffof on top to lower the ph. lol Cuz ph is low now on it! Plus you know the rock wool is always the same you know what you have!
Do you check your run off ph and ppm? ppm should be 600-800 or close to it?

MrGhetto, If you want a medium that is way better then rock wool, then you should think about growing in COCO. I have grown in all kinds of soil, rockwool and aero and such. And COCO is by far the easiest medium I have found.

use straight coco? I heard it good too. Its like rock wool the problem is keeping the ph down? Already bought the rock wool! The roots love this stuff!!!
