Blueberry Muffin under EVO-Series

Hey Guys. Here we go for this first week of growth. Growth 0 to 7 The nutritive solution has evolved during the week. I started with a PH of 5.5 and an EC of 0.8 to have this evolution : 26/09 PH 5.5 EC 7 27/09 PH 5.7 EC 8 28/09 PH 6.2 EC 8 29/09 PH 6.5 EC 8 30/09 PH 6.7 EC 9 01/10 PH 6.8 EC 9 Addition of 10L of water without anything else to lower EC 02/10 PH6.8 EC 8 03/10 PH 6.8 EC 8 As you can see, I had a big increase of the PH this week, nothing very abnormal since the buffering of my clay balls was not enough. I deliberately did not use a PH down and let my PH fluctuate. This day at growth 7, I empty the tank and change the nutritive solution. I start with 60L of solution for : 2ML/L Sensi Grow A & B 2ML/L Voodoo Juice 2ML/L B-52 This gives me a nutrient solution at PH 5.5 EC 1.2 TEMP 19°. I should no longer have such fluctuation and keep a correct ph to maximize assimilation. For the lamps, they are now at 40 cm and 40% intensity about 350-400 ppfd. I will switch to 60% next week and keep these settings for the end of growth. I removed the BBM 5 which was not growing and did not seem to want to bloom. It is the one which had posed me of the problem since the beginning of the germination. See you next week
