Read what is says on bottles. Most likely you have to use both together but directions will explain it better. Because you have to add A to the water before adding B and don’t start at full strength start with 1/8-1/4 what the bottles say and as the plants grow you will increase the feed rate. Also since your in coco you need to have a way to test the Ph of your feed water before giving it to your plants.
We can explain it all but it’s best you do some research on the link provided above first.
And best of luck to ya

i read the directions and a know it alredy. i did water with nutes now. now i ll watch it and see if they grow. need to read more about coco too

Do you have an EC meter and PH meter?
Those are some of the best tool you will need for growing in coco till you get a handle on how they grow with your setup.
I normally don’t test the EC of the feed or runoff unless I see any issues then I will start taking reading before I feed and read the runoff to see what may be going on but other than that coco is fairly easy to grow in if your environment is dialed in and you have the tools to keep them growing.

I don't have EC meter . Just the pH test (drops)

If you can get a decent EC meter and PH tester so it’s more accurate because in coco you want the ph to be between 5.5-5.8 during veg and 6.0-6.3 in flower is best. And you want the runoff water to be no higher than 300ppm above what your feed is. That should keep ya growing

I will do. So I should measure the ppm before feeding and then measure the ppm of the runoff and check if is no higher then the initial ppm?
 
I water with nutes twice , 1 day with nutes another day did not water and I water again with nutes yesterday. Looks like I have some nut burn . Should I water with plain water now?

As long as it’s not too high above the input feed. 300 ppm above the input is perfect but if it’s much higher than that you need to lower your input more or just use more volume to get the runoff lower. As long as it’s not crazy higher than the input you should be fine.

When you say more volume ,are saying more water/mutes? How I lower the input?

Yes water with more volume of water/lower nutrient strength till you get lower runoff. As long as your runoff isn’t crazy high compared to your input feed you should be fine and just make sure you get plenty of runoff to avoid salt build up. It’s actually pretty easy to grow in coco once your environment is dialed in.
You will get your head wrapped around it in no time and be cranking out good medicine. Just keep it simple and keep notes till you can read the plants.

Can I measure the runoff straight after water?

So basically whe I have higher ppm that means I'm giving to much nutes?

The initial/input ppm matters?
 
Your coco is dry, they are dying. Feed daily at PH 6.0 and a EC of 0.7 - 0.8 if you water is hard. If it's soft water then give them about 0.4 - 0.5 EC. Make sure your light is dialed in properly as well.
