2. Grow with Gorilla Cookie Autoflower seeds. The deficiencies on the back left look like those on the back right, I think phosphorus based on the pictures, and in the front, it's pretty much a mix of everything but extreme. The only bud that smells when you touch it is the one from the back right, the others don't.

My seedling doesn't look so good.
This is my first coco grow so could be possible that I made a mistake. The other three seedlings are super healthy but this one has this weird thing with it's leaves. Somebody seen this before? I gave them some root juice and fertilizer before transplanting with ph between 5,5-6.

Dark tips
it seems to me that the tips of the leaves have a very dark color, it looks like an excess of nitrogen but in three weeks I have never fertilized and the only additions to my biobizz light mix are a sprinkling of guano kalong and 10% of worm humus biobizz.
