First time on pure Coco

Good luck and happy growing! 😁

I see some root tips on a few Black Sugar plants, but not all. Peyote Zkittlez... not much to see. Lava Freeze, also a few root tips. Royal Amnesia... nothing at all... I think they might be too old by now. All lamps are still working, unfortunately one dimmer is out; I'll order a new one tomorrow. Currently running at 50W except for the last one, which is running at 240W. Extractor fan naturally not installed yet; unnecessary noise and a high humidity level are appreciated in the beginning (basement from 1930s). Water EC is 0.3, water pH is 7.6. EC is now at 1.4 (250-liter tank, 250ml rootfast, 125ml CalMag, 125ml AtaZyme, 125ml ATA Awa Leaves A+B) pH 6.5, Temp. 21˚C. I took 30 liters of this mix to water the coconut and this served as the reference value for the Blumats. Now hoping it works directly from the tank through the Blumats. If so, a very cost-effective hydro setup. Yes, it says 250 liters. Unfortunately, the nutrient tank ended up being slightly larger. It just doesn't fit under the boiler. If I'm doing something completely wrong, please let me know. I've been out of the loop for a while and only have experience with Blumats combined with a Blumat tensio. Unfortunately, I've sold all that stuff and don't plan on buying it again until I make a definitive decision about the house."
