I never measure the ec of the run off though, do you think I should start doing that? What run off ec should I be looking?

 

You should 100% be looking at the run-off mate it's one major way to see what your plants are actually taking up :)

 

There is a lot of very useful info on the benefits of measuring run-off and what readings you should be seeing throughout the grow ;)

 

I can't put a direct link here as it's to a secondary site so I'll pm you the link :yep:

 

All the best

Cheers for the link Mark. Ive just measured my run-off and it's reading EC 5.8 which seem bloody high to me! I'm two and a half weeks from harvest now so have just brought my nutes down to EC 1.7 from 2.4. After reading the article about run off it's sounds like mine is WAY too high but all the leaves on my plants seem fine and have only the very slightest nute burn on the tips so not sure what that's all about. I'll take reading of my run-off again tomorrow to see if it's any different.

That's super high mate, I think with that much built up feed in the medium I would swap out to just water. 

 

If you putting in say 1.5 e.c and test your run-off that should ideally much lower than what's going in, say 0.4 e.c run-off from 1.5 e.c going in. This let's you know the plant is taking up 1.1 e.c  :yep:

 

I would just water until you get a runoff reading of 1.4 e.c then start back in with a 1.2-1.5 e.c feed :bong:

 

All the best

What do you think would be the effects on the plants of having such a high reading from the run off? Wouldn't it show up on the leaves? Or could the plants look fine but the yield be reduced?

Typically we would be seeing some signs of overfeeding, posdible leaf tip burn etc :) are you not seeing any signs of overfeeding other than your high e.c levels?
