Yeah mate as the guys have said there. Quarter strength nutes, 1ec/500ppm.
Ph5.7-6.3
Feed every day to full saturation and run off.
That's it mate. All there is to it.
Do that and you literally don't need to know anything else cos it can't go wrong.
For veg phase anyway.
If they get pretty big they'll go hungry eventually. They tell you by going yellow, you see it, up the dose a bit and all is well.
Takes a fair size plant to go hungry at that though. Cos you're feeding every day they don't need much at all.
Nute company just tell you to use loads so you buy more.
