Hi guys I'm fairly new to growing only have one under my belt. I've just purchased the CX horticulture range. They have a bloom/booster to use 1ml/100ml. I've just added it in my second week of flowering as per instructions. I added it after base nutrients when my PH was 5.9. After adding the bloom PH shot to 7.4. My EC is 1.4. In Is this Normal for PH to rise so drastically? Is it safe to use? I'm presuming i shouldn't use PH down with any kind of bloom/booster. (I think i read it somewhere)
