What am I doing wrong

Ok I’m on my 6 weeks from seeding and I have a problem with my leaves drying out and getting spots on my bottom leaves.

Medium: foxfarm bushdoctor coco-loco
In 5 gal fabric pots
My feeding has moved to every other day and that’s
Cal mag 20 ml
Flora bloom 20ml
Floramiro 20 ml
Floragro 20 ml
Every other feed clonex ml
All mixed in a five gallon bucket to water 20 plants so I’m doing this mix about four times each feeding giving my plants almost 1 gallon .
My temp is resting at 80 and humidity at 60

Are you in flower now? Visually those look like a nute burn issue. Did you adjust pH and check TDS after adding nutes to your water? What are those values?

Some of my plants are in flower and some aren’t
I’m at 6.2 for my ph and I checked my run off before it was at 6.5 and this time I don’t know why my run off was 6.9

The sweet spot for a coco grow in terms of pH is going to be @ 5.8...yours is too high (most likely the cause of your problems). I'd take another look at your pH and dial it in before you chase a deficiency. Once your pH is dialed in, then you can make adjustments if needed. Otherwise, you'll just be chasing your tail.

Do you have PPM values for your feeding? On first math I think you might be overfeeding a bit. Other guy could be right as well, if pH is out of range too far plant won’t take up nutes at same rate. So could be combo of both.

It’s just parts per million, tells you how ‘saturated’ your water is.

edit: if you measure before and then measure runoff you can see the difference to see if you need to feed more/less :) it’s really simple actually

If it were me...I wouldn't do a so called 'flush'. Just mix up a new batch of feed and be sure it's between 5.5-5.8 pH and water them. I don't generally shoot for high a % of run off, but in your case don't be afraid to run adequate feed, pH'd accordingly, through your pots. This will help 'reset' your pH. Good luck friend.

When I checked my ph this last feed it was really high

That's your problem...

So make your feed, pH accordingly, and run a proper amount of feed through each plant. For the future, unless you're trying to grow 7' trees, I wouldn't use such a large pot when growing in coco. Good luck friend.

using 20ml of each sounds like a lot. I doubt if the clonex is necessary. feeding every other day sounds like way too much. leaves show over fert with dark green appearance and brown, dying tips.
