Hey guys,
I just can't get seedlings to grow nicely in solo cups with coco/perlite, and Canna A+B. It just never works, I kill one seedling after another with severe overwatering symptoms. Droopy leaves, brown spots everywhere, seedlings turning pale yellow, just typical for "too much water".
What am I doing wrong here? I put holes in the bottom of the cups (lots of them), fill them with Canna Coco Professional Plus and 30% perlite, then prewater every solocup until some runoff with a light nutrient solution of around 0.8EC (RO water + 0.3EC Calmag + 0.7EC Canna A+B, watered down to 0.8, PH 5.
. I then plant the germinated seeds, humidity dome on top, sprout 1-2 days later, and then they seem fine for 1-2 days. Afterwards, growth slows down extremely, they turn a pale green, droop down severely. I tried watering every day til runoff, in another attempt I tried letting them dry out, but they just don't grow NEARLY as quick as I'm used to with Biobizz or other substrates. By day 7 after sprout I usually have the third set of leaves growing outwards, with coco I usually still have the first set of leaves, with the second set just slowly pointing out of the stem. Just INSANELY slow growth, especially bad for autoflowers.
My temps are alright, around 74-77°F, 60-65% humidity, I got air circulation, air exchange, everything is running perfectly fine. I don't know why my seeds are always severely stunted in coco, and why they just turn to trash each and every time. The worst guide that killed my seeds the quickest was the cocoforcannabis guide, I'll never touch that website again. Does anyone have a rough guide on how they start their seedlings in coco and solocups?
