6.3 is a bit high for coco.
What nutes are you using?
Based on the color they need more food.
How old are they?
Did you buffer the coco?

I thought it might be a lil high. I'll lower it.
Gh flora trio, but running h3ad formula, so no flora gro.
I figured they need more, so I'm guessing that .5ec is too low,?
They're just over a week old.
Canna coco bag says pre buffeted.
This is my second grow with coco, first with seedlings. Kinda playing it by ear.

For sure. I'm gonna lower it some for next watering.

What's your plan for final containers?
Also coco has a higher CEC than peat so don't hesitate to feed more frequent as they grow, especially if you are staying with pure coco. If your going to add peat when uppotting I'd suggest some straight watering in-between feeds and you may have to lower your EC of feed. Decreased CEC

How much micro and bloom are you using? I would start with 2ml micro and 3ml bloom.
What water are you using?

2 gallon containers.
I did my last plant in one 5 gallon. I set autowater for 5 times a day. Straight coco.

I use 7ml micro, 9 ml bloom, 1 gram mgso4, in ro water. Then I dilute to. 5ec.

I think the main problem is your Ca:Mg ratio is way out of range with RO and that nutrient mix.

Why not just use lower amounts of micro and bloom instead of diluting it?
H3ads formula is a 6/9 ratio, not 7/9.
Even though your coco is buffered, it's a good idea to use a calmag supplement when using ro water, at least for the first few weeks of growth.
What's mgso4?

Epsom salt

Hit 7 instead of 6 on accident, but I was using 7ml on the last run, due to pale leaves.
Mgso4 = epsom salt.

If you want to learn what the problem is don't change feed and PH at the same time on all plants.
Increase the feed on 2 plants and only change the PH on two others. You will likely find the plants respond to one or the other. My guess is it probably only needs an increase in food. Find out by only changing one thing at a time. Results will be seen in less than 48 hours if it was in need of more food.

Advice taken.

Im not adding any additional calmag. The formula calls for a gram of mgso4 per gallon.
You might need to balance the MgSO4 (magnesium sulfate) with some Calcium. I find GH's CaliMagic is a nice ratio of Ca to Mg.
I start my res with a pH of 5.8 and allow it to swing to 6.3. I hope you like Coco and GH Flora Series. I use their DTW chart.

By upping your micro you're pushing the ca over the k. Head cut the Epsom because it causes more problems than it fixes. (Edit: more problems with his formula. Epsom is obviously a great way to add mg if low)
By upping the micro and adding the additional magnesium it could be causing your issues.
