Coco-based hydroponics (C-BH) 2

Report on week 3 of veg: I lower the RH to 50-55% while the RM stays relatively on the higher range: 27-29C daytime and 18-22 at night. I had nice visual on the 6th node of BB3, Larry Bird and Gelato plants and few cm. to avoid any eventual stem splitting, so i topped them. I guess the Gorilla will be ready for topping by tomorrow. Unfortunately i have to work with hard water so i have to keep constant eye on the water's EC. For this reason and from personal experience i wont increase the nutrients dosage any time before flowering. The high percentage of worm castings is doing wonders and help me a lot with the substrate's maintance. I did some runoff water measurements and end up with the following values: Gorilla had 2.75EC and 6.5pH, Gelato got 2.70/6.6, Larry 2.85/6.7 and BB 2.20/6.9. Substrate pH is 7.0. Once again, I have to say that Sunmaster's Dual Spectrum HPS are indeed super powerful lamps. I added another clip-fan to ensure a nice breeze around the plants. I will follow the general rule of thumb and give the plants 10-14 days to recover from the HST. Once i week i spray the plants with foliar iron-based nutrient solution👊 (Plagron Vita Race). It boosts the photosynthesis, plus it washes and cleans the leaves. P.s. only the Larry Bird is topped on the pictures. I topped other two today, but i didnt want to switch-off the lights in order to take pictures. Peace!
