ulmer the 4th plant - Swiss Dream CBD was later removed - gave them EC 0.7 at this point which in hindsight was way too light.
Had some issues finding the right drip darts as floraflex darts were sold out everywhere in europe
used some really wild mix setup of Gardena - Floraflex Bubbler - Drip darts from Amazon

ulmer My low EC + 40% Power of my Sanlight lead to yellowing of the leafs - after raising to EC 1.2+ problem was fixed. In hindsight i raised the EC too slowly which i'll fix for the next run.
At this point in time my watering was fully automated using a Fritz DECT200 - this was managed by a python script on my Home NAS Raspi - i made the script publicly available here https://github.com/heyjan/fritzbox_water_automation
Watering schedule was 9 shots in total for 60 seconds each

EC raised to 1.9
Learnings for the next run:
Don't top + faster jumps in EC should give me faster vertical growth and 1 week less of veg.

ulmer Beginning Week 4 - EC 2.3 - PH 5.7
End Week 4 - EC 2.8
2x Extra Shots
Big Fan leaves removed
Lamp 5cm higher.
- On the top shot you can see the yellowing of the leaves at the beginning of the week. EC was too low for the Light Exposure. Higher EC fixed this.
- You can see some algae starts to grow on the top of the blocks - i fixed this issue with some plastic sheet cover.
Amnesia K Lemon seems to take the longest to recover from topping
BCN Diesel CBD seems to be a very impressive pheno
La Blanca seeded 3 days later than the others, already surpassed the Amnesia K Lemon

ulmer Had some low PH issues in my drain. And was scared that it could be root rot or salt buildup. As a solution ive made some DIY Hypochlorous acid.
Ive also ordered Athena Cleanse but it took a while and in the meantime ive used the DIY which had the exact same smell than the Athena. In hindsight Cleanse is a pretty expensive mix of water and salt.
But anyways. It helped immediately. Brownish roots at the bottom at the block turned white again and PH normalized. Plants looked healthy all the way, even with a PH of 4.0 in my drain.

ulmer Not much to say...
Athena Cleanse runs at 12ml for 16L rez now
EC is steady at 3.0 - Drain EC was at 4.6
At the moment i need to refill my Rez in a 4 day Cycle
Ive implemented a weekly Flush to keep the Hugo Block saturated at the top as well and to prevent too much Salt buildup.
