Depends on what nutrients is in your soil, also, it depends on how often you use nutrients, i.e., once a week or every watering. Plain water or nutrient solution at 1/4 strength of your normal strength with decent run-off will help lower your EC if it gets too high.
I like to use a low EC, usually no higher then 1.2 or so during peak, but feed every watering. Soil users usually feed every other watering. What soil are you using??
I don't have experience with BioBizz, but look on the bag at the ingredients, if it has alot of compost, bone and blood meal, kelp, and other stuff like that, then you probably don't have to use nutrients the 1st week or so. If it just has a few like peat moss, coco, compost, ect. then IMO you should use nutrients right away.
If its just peat moss, perlite, coco without compost, I would drop the pH to 5.8-6.2., but if it has all that compost and organic nutrients in it like FF Ocean Forest then I would keep the pH around 6.5.
Rootbound, the pH I keep at around 6.2-6.8 and the EC i'm only going to be able to test for the first time tomorrow as Amazon f'cked up my order for the meter and i've been assured it'll arrive then.
What is a good EC level and the best way to lower it if it is too high?
Canna, I saw in your first post that you thought there might be a problem with Mg, and that's where I'm landing pretty solidly. But, not 100%, so I'd like to know if you've tried one of the diagnostics for figuring a Mg-, which is to give a foliar application and see if the treated plant greens up. If it *is* a Mg-, then you give a foliar of 1/4tsp MgSO4 (Epsom salt) per gallon water with a surfactant (dish soap, nonantimicrobial, please). Sometimes the change occurs in only a matter of hours, but usually by the next day you can see.
Have you done this? If not, consider trying it on one or two of those plants. If they green up, then that's the tell right there.
Just a few drops, unless it's Dawn, and then I'd only use one drop. Make sure it's not an antibacterial/antimicrobial soap. Don't want to add to the problem of resistant critters.Thanks Seamaiden, the short answer is no, i've not tested for a specific deficiency, I arrived at that through nothing more than a visual diagnosis. Being that it's my first time I don't know that much about that sort of thing. Your method above sounds like a good step so I'll definitely try that.
Out of interest how much soap would you use per gallon and do you recommend a specific brand?
Thanks again!

Lex, I use soap or JMS Stylet as a surfactant. This breaks the water surface tension and allows whatever you're spraying to 'stick' and 'spread' and then it can be more easily taken up by stomata. In the ag world I believe JMS is what's more commonly used, but for me, soap also works just fine. Like many things, a little goes a long way.
Just so as i'm clear, do you literally mean a liquid soap you'd buy to clean your hands with or the sort for washing dirty plates etc.? I understand the theory behind not using antibacterial/microbial but didn't want to use something that might later harm the plants defences.
I know i'm only new to the game but using this sort of product isn't something i'd evr envisaged having to use.
Yes, actual dish soap, but only when using as a foliar, not in the medium.
There are lots of things you will learn, just keep at it. I've learned more in the last year growing indoors and researching on this site then I did in the last 4 years before that combined.
What you'd use to wash your dishes. I believe in the UK/Europe it's called washing up liquid, if that's more helpful for you. IMO, the cheaper the better.Just so as i'm clear, do you literally mean a liquid soap you'd buy to clean your hands with or the sort for washing dirty plates etc.?

I've been using some super-cheap stuff I picked up at the dollar store as part of my Neem emulsion, on seedlings of all sorts, root drench. As long as you go easy it's not a problem.
These are tricks that can be used with many plants, not just cannabis.
Oh, you could also use the wash water from quinoa, as it's high in saponins (again, sticker-spreader).
