Week 6: Switched lights to 12 hours yesterday. You probably notice that this is now a sequence of pics from 3 phenos. As the layout is symmetric i put one Big Bud pheno under the 2 q1w in my bathrooms open space grow where i also grow herbs and finish auto bubblegum. I'll open another diary for this plant.
day 36: My camera messed up the pic from the central Big Bud pheno. It's the one with to colas on top. The idea was that i can stretch the other plants around the central one towards the center. I'm eager to see how tall they will grow. I LSTed the Biggies in the last grow and they were about 50 - 60 cm in height.

I recently had a Big Bud grow with seedlings i bought from a local store. I found 2 speckled proper looking seeds. This is one of them. The other one is watering and will maybe join here.
I harvested the foregoing Big Bud grow after 7 weeks. Impressive that they can also produce developed seeds in such a short time. It's sharing Homebox with the Auto Bubblegum Extra grow (BulkSeedBank) i run at the moment. I also just put a few Cocopopo and Watermelon Jam Seeds, both from BulkSeedBank as well, in Eazy Plugs and they will also join the tent. Planning to top and train them in 1 l pots as well as this big bud specimen, in preparation for the plants in the following link leaving the Homebox.

Hi buddy your soil looks to me like it has no perlite, so the oxygen content in the soil is too low.
The result is waterlogging.
What is the PH value of your irrigation water?
Are you really measuring it?
How often do you water your plants?
How far away is your lamp?
What is your dimmer set to, if present?
@AcidBurn_40, Everything fine again. It was too much water for the seedlings, you were right. It was my fault, cause i thought i can supply N via just the coffee grounds solution and therefore i watered a lot. It's been a while since i grew my own seedling and i forgot that they couldn't compensate their accellerating growth with the already built up leaf mass in case of a nutrient lock. Thanks for your hints!! :) Meanwhile i use my urine to feed N instead of the coffee grounds solution. I'm processing the coffee grounds now with my kitchen waste in a Bokashi,, to experiment with in future grows.
@AcidBurn_40, That's right it has no perlite. I'm trying to avoid buying this cause of it's carbon footprint. So i took a sustainable seeding compost for the young plants. The soil has got a loose structure using other things than perlite just like trees needles. Maybe i was a little to generous with watering since i moved them to the new pots. Will let them dry a more before i water next time, which is usually once in 24 hours. Thanks for the hint.
Do you mean the ph value of the rinse or the feeding? I never had problems with it so far and also never measured the rinse.
The distance between the lamp and the plants is 38 cm. The lamp is not dimmed now running at max 205 W.
