High ppm

Hi guys just after a little help, currently growing an auto setup 13 days since germination and feeding advanced nutrients. I’m feeding 0.5ml/ L of grow micro and bloom and 0.2/ L of roots & 0.5ml/ L of cal mag. This is bringing my ppm out at 900 ppm once I have PH’d to 5.9.

is this too high?
im Just sticking to the chart I have but I have read online that it should be around 200/300 ppm for the stage I am at what do you suggest I do?
Cheers

my water is 550ppm out of the tap. My ppms are way high. I havent bothered worrying about it, last crop was beautiful and no problems. Except yellowing before flower which self fixes.

You do know coco is feed daily with low dose of nutes

Where does it say those amounts are per L????

I feed everyday around 650ppm currently in coco it just depends on the roots size of plant environment etc. The idea is not to let the medium dry or you will get salt build up and burn your plants. If you find the need to flush make sure that you flush with a low nutrient solution not plain water. At your stage I would shoot for around 350ppm to 400ppm. I float my ph between 6.2 to 6.6. I am very new to this but here are my results so far.good luck hope this helps!

So i would make the solution they suggested And then just dilute it down with some good water until you get the desired PPM you want.

So you say feed daily? How can I be sure to not overwater when doing so?

Careful with incorrect advice

Coco is 5.6-6.0 ph
1/4 strength nutes
Feed daily, some feed 2x a day

Lots of good links in these forums on growing in Coco, read them my friends

With coco I ph between 5.8 and 6.1 the ppm you want depends on What the plant tells you. I run my ppm 700 and 800 I feed twice a day with 10 to 20% runoff each feeding. When you add nutrients ex my water is 200 ppm no nutes add 5 ml cal mag brings it up to 450 ppm add sweet raw brings it to 500 ppm add 5ml bloom nutes until I get to desired ppm 700, 725, 750 exc. Then I will stir solution and ph up or down 5.8 to 6.0 i will adjust the ph between this number to allow the plant to take up all available nutrients.
