The First One

Plants grew a bit long so i lowered the light. PPFD app on phone then showed ppfd of 350 which is fine. I replanted the plants into 15L Buckets early at the end of week 1 one Because it helped me to keep the Humidity up in the tent. 80% and 74F (24°C) which gives an optimal VPD for this stage. Also, i started to feed them with BioGrow from BioBizz at a TDS of 0.8 and at pH 6.2 -6.5 when the first two leaves appeared. After the 2nd pair of leaves appeared, i started to feed with a TDS of 1.2 and at pH 6.2 -6.5 . The plants were- and still are- happy. When i transplanted teh seeds i used soem mycorrhiza in the hole to stimulate root growth. To lower the pH value i use organic Lemon juice concentrate that contains citric acid. Works fine. To make it more alkaline is just use kitchen soda (Sodiumbicarbonate) The buffer would contain sodiumcitrate which is some extra sodium for the plant. The bicarbonate poroduces CO2 and gasses out. The rest is water so jeah no pH up or down needed all products of this reaction are well tolerated by plants. 😋
