Hi, Guys, does anyone can help me out on this?
This babie growing in coco coir is being fed 500ml for the first week and just now switched to 500ml twice a day 2 avoid dry medium.
looks strong but this strange pattern looks not good how I can fix it? and what it is exactly it? x
You are massively overfeeding here... autoflowers generally don't need ANY nutes for the 1st couple of weeks. I would suggest you do a good flush to get those nutes out of the coco and then give her only pH'd water for a week. When re-introducing the nutes, start off with 1/4 strength... if they respond well to it, you can increase but never give full strength nutes to autos!
Good luck!
it could be Septoria, hard to be exact from pictures,,google it and you should be able to tell since you have first hand view of the leaves, and get info on reasons and fixes
