T.H. Seeds London Mint Cake Coco Autpot

stadtgaertner She went from 25cm to 95cm in the first two weeks of flower. Long internodial spacing. Not very bushy. Fast growing. Very nitrogen sensitive. 120ppm is borderline nitrogen toxicity. Overall she doesn't need a lot of nutrients especially in the autopot. Running straight coco with the airbase in the autopot. She takes high light intensities with joy and prays all day. A very happy plant makes a very happy grower ;) Not going to defoliate this plant as it is not necessary at all. Removed some of the lower bud sides but thats it. Going to drop the nitrogen some more to deal with the burned tips. You will find my nutrient solution in the pictures, Hydrobuddy screenshot. Might drop the Calcium Nitrate and replace it with Canna's Mono Calcium.

stadtgaertner Added a second fan to increase air movement.

stadtgaertner 07-18-2025 Humidity skyrocketed to 70% during the last couple of days. Fingers crossed my airflow is good enough... 07-21-2025 Dropped the nitrogen in the nutrient solution to about 100ppm. You can find all the numbers in the hydrobuddy screenshot. Two days after dropping the nitrogen the terps got a lot louder. I guess it's true what they say about nitrogen in flower...

stadtgaertner Started using Canna Boost about a week ago. Noticeable increase in growth and dank. Using 1ml per Liter in the reservoir. I was hesitant because of the high price but this stuff is great. After playing around with the Masterblend ratios and weights I feel pretty confident in my current mix. What I thought to be tip burn from nitrogen turned out to be the early stage of Calcium deficiency. As Nitrogen and Calcium come in the form of Calciumnitrate you can't drop the N without the Ca. To avoid this I bought Canna Mono Calcium with 11.6% Ca. Now I am able to dial the N down to 120-130ppm and keep my Calcium at about 150ppm. Anything lower than 120ppm of Calcium starts to show deficiency symptoms. Same goes for the Nitrogen, 120ppm is the absolut minimum right now. I am also going to increase the Magnesium to 50ppm with the next tank refill. I am pretty happy with the Masterblend 4-18-38, Calnit 15,5-0-0 and Epsom Salt bundle. You don't have to buy a seperate flowering blend if you get a mono calcium fertilizer. The plant loves the Masterblend. Looks way better then when using Canna AB...

stadtgaertner At the beginning of week 7 of flower she started to fade. Her leafs started to get dark purple starting at the bottom. At the end of week 7 of flower there were first signs of amber trichomes on the top buds. I will wait until the lower buds are mostly cloudy before harvesting.

stadtgaertner 08-10-2025 Still putting on weight. Still some clear trichomes. 08-13-2025 Already some amber trichomes on the top buds. Going to harvest next weekend when the temps go down again. Not going to cut her down now as we have about 30C for the next two days. Should be back to 21-22C on the weekend. Diluted the nutrient solution down to 1.4 EC for the last couple of days.

stadtgaertner Cut her down at the beginning of week 9 of flower. She already got some amber trichomes on the lower buds so it was time. Defoliated her quit a bit as my drying humidity is quiet high. Will report back once drying is finished.
