Tropicanna Cookies x Purple Punch - Custom Living Soil

[Day 8 - 20.08.] Pots felt lighter today, so i watered 25ml filtered rainwater with nutrients per plant. Doubled the dose of nutrient fermentation to 4ml on 200ml water (1:50 ratio). Expecting some growth over the next days. They seem to be outgrowing the Mandarin Cookies currently, but i think that is gonna turn the other way later, so its fine. --- [Day 10 - 22.08.] Big growth over night, but noticed yellowing in the middle. Either my ferment is stronger than i thought or they grew too close to the growlight. Should have tested the ferment on one seedling rather than all of them, as its my first time making and using this stuff. It has got a lot of fish hydrolysate and kelp in it. - Distance to growlights increased to 30cm - Flushed with 30ml plain filtered rainwater --- [Day 11] I had to cancel this grow, the plants started drooping a lot looked worse and worse over the hours. Pretty sure it was not too many nutrients but simply overwatering what killed them. Comparing the substrates, i am going to switch back to pure living soil for the early stages/small pots, as i could only see disadvantages here. I think that is going to be different in later stages of growth, we will see! Check out my Ethos Mandarin Cookies grow if you are interested to see the project evolving! Going to start some rainpop x zero gravity by clearwater genetics soon.
