OK, so I got a lot of advice before buying my setup, but now I feel like a fool when reading about what to feed my plants when it comes to it. So I have a lot of questions, sorry. I'll number them to make it (hopefully) easier to answer!
1) I'm growing in rockwool blocks in coco coir. I was told to use Vitalink Max, but I now realise that is for hydro setups not coco.I guess it would work but I guess also that I am better off getting some Canna coco a+b, is that right?
2) EC....I just about understand. Electrical conductivity, higher due to salt buildup in the coir yeah?
3) But do I *need* to measure this? The testers are expensive and I am poor (tight).
4) Can I just go on a schedule of watering every 2-3 days, and every 2-3 waterings give a feed according to the chart on the bottle?
5) Should I flush them on the last watering before the feed watering? I mean I will water each time until I get some runoff from the 15 litre pots but should I *properly* flush?
I feel like an idiot having got this far without really knowing what I was doing about feed. I also kinda wish I'd used soil, but I'm too committed to change now hahah! Thanks in advance....

I no longer ph i know what the ph is in the buckets i use 5.8/6.0
far more important is knowing the ec if the lights are kept on the
tops,so the nodes will be close then you will get a nice yeild.
I do 3 plants under 2 x 600 hps lights and a 600 hps with out a hood
so it can be dropped any where in the room.the other 2 lights are cool
hoods with a 10 " fan pulling air through the filter then through the lights
then vented out of the room into a loft space,8" inlet that pulls air from a hatch
in the loft then pulled through 8" duct that is along the grow room floor with holes
punched in the sides so it is evenly spread along the bottom of the room.I only use
the 3rd light on cool days if its warm then i know the two lights are ok but i dont add the 3rd light while about week 3/4 of flowering any how.winter i use all 3.
Hope that this helps i use aqua flakes a/b,but it will work with any nutes done it with canna vitalink advanced
