I'm a soil grower myself so not really sure but isn't the ec meant to be lower but not to worry someone will help soon

EC 2 is huge. What's your BG EC?

You should be water/feeding daily and not letting the coco dry out too much

My last grow were getting EC1.2 including BG 0.4 when full tilt. Towards the end dropped to 0.8

I've been using a feeding schedule and it shows what ec needs to be only been increasing gradually that's including base ec

Ooh dear What should my ec be?

Try half that mate and build it up from there, go for 1.0, and bring it up step by step with every feed until you see signs of over feeding ( tips of the leaves getting brown and clawing) well, you don't want to see them signs but if you do, go back to a lower ec where it didn't burn. You always find, the manufacturer recommends a certain amount, they obviously want you to use as much as possible, as quickly as possible so you buy more, always feed half what they recommend to start with, and increase feed as the plant grows. But if you see signs of over feeding, stop increasing. Also make sure you do a flush of the soil every two weeks to remove any built up salts, and ph test an ec your run off to see if the plants eating it all, or leaving some behind, and figure out the ph of the medium too.

Hope this info helps you out a bit man,
