This is already my 3rd grow so I've got some experience in same cases but not all of them.


Grow Info:
Light: 400W HPS - Philiphs Son-T Agro
20" fan
10l pots
4x Short Ryder Autoflowering
L = 1M, W = 60cm, H = 1,5m


I've made some research and from what I've read, it might be an Iron deficiency but I'm not sure. It happens only with the new branches and leaves which start growing. In the middle their brownish going towards a yellowish color on the outside. Other "problem" which I noticed that some of the leaves are cut on some spots. I've looked over all the plants and only this one is showing this kind of signs. There are no insects of any type. Now for vegetation I'm using the Substral Vita+ fertilizer: Substral - Kasviravinne


I've uploaded some picture for a better assesment from a professional POV.


In photo 3 you can also see those small cuts.
