Hey my beautiful people!
I am stupid. This is the first thing I had to say now. I am losing my mind, I am losing every last piece of hope I have. I cannot for the LIFE of me grow weed. As dumb as it sounds, I kill them all, each and every time, in the early stages.
I’m from a country where Biobizz is pretty much one of the only options I have. I could build my own soil, but it’s so insanely expensive here, it’s something for the future IF I succeed with such a simple substrate like Biobizz. Please try to understand. I wasted around $400 worth of high quality seeds, from premium brands to low quality ones too. In 1 year of trying to grow, I had 2 plants which survived, one severely stunted, the other being 100% fine, no problems at all, yielding 7oz.
My goal is to successfully grow a few autoflowers. I tried photos too, and had the same exact problems. I am talking about severe yellowing at the new growth of my plants. Inside out yellowing, really bright.
I went through hundreds of posts, hundreds of hours of videos, tutorials, guides, I checked every possible growdiary with this exact substrate, but I never achieved success (Only once, with no changes to what I do at all). I did seed to soil germination, I did watercup → papertowel → soil, I did watercup → papertowel → jiffy → soil, the list is long. My germination stage is crazy good now, because I always kill my seedlings later on, which means by the time a successful grower did one full grow, I probably did 10-15 germinations. It takes 3 days from taking the out the package, to showing their first set of leaves after the cotyledons. I trust this stage 100%, I mastered this & don’t worry about this stage one bit.
But afterwards, I just don’t know what I’m doing wrong. I did pre-soak my Biobizz substrate (tried light mix and all mix) once, with little runoff, 6.5PH tapwater, 0.3EC, then let it settle at 75°F for 3 days until I planted my seeds. 10 days later, my seedlings have new bright yellow growth coming out, severely stunted, then no growth for 10+ days anymore. A death sentence for autoflowers. I then did soil straight out the bag, no presoak, same thing happened sooner or later. My plants look absolutely wonderful, a rich dark green, nice growth for the first 3-4 days, and then suddenly they all become slightly lighter of a green, new growth is suddenly bright yellow, and then just nothing anymore. They die off, with the leaves all suddenly becoming a mushy light brown on the edges and tips, everything hanging down. That’s the end-stage if I wait long enough.
My temps are wonderful, humidity is wonderful. Everything 100% smart controlled and stable, air exchange, oscillating fans, my tent looks like a space station because I am insanely stupid & thought something else may be wrong, but I feel like it’s me. I am the problem.
Does anyone know what may cause this EXACT problem every time? I am almost 100% alone with this. I rarely find images on Google about this problem, and never a solution. Maybe 3 or 4 images altogether on Google, not kidding. It looks 100% like an iron deficiency, but it can’t be an iron deficiency. There are 5000 images for every deficiency, yet only 2 or 3 for my problem, but 99% of my plants died because of this exact problem.
Here are a few example images. They do not look severe, they look laughably boring, but these growths are always a death sentence for my plants, every time. Don’t judge about the lack of severe “problems”, but try to think about what might be causing this. I know how severe these problems are, because all my plants pretty much stopped growing because of this problem, and never recovered.
I will add any detail you need. I am completely hopeless, even had a professional grower check my tent, someone with several successful grows in Biobizz substrate. He had absolutely no clue as to what was going on. I hope someone can help me.
others will jump in soon, I’m sure
on the assist
