Alright and welcome to week 4, day 22. As you can see something is wrong. I think it's some Mag that is missing so I added some MagO 10 and I hope the problems will go away. If you guys think it is something different, leave a comment and we can discuss this 😎 I raised the water to 1.2 liters a day. I also wondered how this could happen. Everything is okay at the measurements so how does this occur? Day 23: The problems are still there but it seems they grew a bit overnight. I added Calcium today because some of you guys tell me it's Calcium deficiency. Well let's check back tomorrow. And wish me good luck! 😁 Day 24: Alright, I suck. I measured the runoff from plant 1 and it was way too high. Just like me sometimes (I forgot to take a picture of plant 4 today, have no clue how that shit happened. Yes I can count to 4 👽). What you guys thinking about EC 3.25 ph 5.9 @ the runoff? I don't think that's good so I lowered the EC in the tank by putting in fresh water. How did it come this far? Well, I probably did not give enough water. Meaning it was enough for the plants, yes, but there was no or not enough runoff. So the salts (fertilizer) came to EC 3.25 in the substrate. I'm "flushing" now with EC 1.25 and will check back tomorrow how the runoff will be. When I measured the runoff from all 4 plants together EC was 2.1 - which is only a little too high, I am trying to reach 1.6 - 1.8 . Let's check back tomorrow. For forgetting the picture of plant 4 today, I made a video. Day 25: The flushing was good. The plants look healthier again and the runoff is only 1.7 now. EC in the water tank is 1.35, ph 5.5. Also I removed some of the downer leafes. And I created this SCRoG net. So I just have to give them more water each day. So much there's about 20% runoff but I don't think I can measure or calculate 20% runoff. So I'll do it by feeling. Seems to work for now. Day 26: Looks like the plants are okay again. I only checked the ph and EC which were good. Day 27: The plants grow against the net. Also there are some waterdrops on the leafes which means that there is not enough air rotating inside the box. Have to check the airflow tomorrow. Day 28: Last day of vegetation. Just ph'ed down a bit.
