Been around looking at posts for a while as a guest. Joined a while back. This is my first grow. I'm in Roots Coco using a Technaflora starter pack for nutes. On day 29 of flower. Feeding every day with a minimum 20% runoff. All was going well until I see yellowing on the leaves of the bottom of the plant and now starting to work its way towards the top. I have a very high EC 2.9-3.0 in the runoff with a runoff pH of 5.9. In veg, worked my way up to an EC of 2.0 (as recommended by Technaflora). Flipped to flower and had some clawing and slight burning of tips of a few leaves. Cut nutes back and flushed with 0.9 EC due to concern of high EC runoff. Runoff lowered some but I still had high runoff EC. Don't know if I flushed enough. I am not doing the feed, water, water sequence as recommended by Technaflora. Using RO . Under a T-5 flouro. Below is what I've seen/watered the past number of days. Any help is much appreciated.
