Is this nute burn? How to fix in coco?

[LeaniLean]

Hello, so I am in canna coco, feeding my auto OG kush with GHE flora trio following From Seed to Stoned's schedule.
Everything seems to be going good except a few of the leaves tips are starting to burn a bit? How to fix?

What ratios are you feeding them? I use the same coco and nutes. What is your ph? Tap water or RO? What are you using other than micro, grow and bloom? How often you watering? Are you always getting good runoff when feeding?

Im using tap water, was feeding every 3 days but I read somewhere I should feed every 2 days so thats what I did the last 2 feeds.. always make sure to get good runoff, im using calmag as well, here is what ratios I use per gallon:

One other thing... I have 2 plants of the same kind and feeding exactly the same, and the other one looks overall more healthy, without any signs like this...

Hey man, so first off you should water coco daily to good runoff. If the pots are still wet it will just take less to get runoff. By allowing it to dry for a few days you are creating salt deposits from your salt based nutes. Because tap water usually contains calcium I would cut that calmag down and add some Epsom salts. Too much calcium can lock out magnesium.

Okay thanks man, I will get right on that! Appreciate it.

No problem. I find this ratio works well with tap water.
CM = 0.33 ml per gallon
Epsom = 1 to 1.5 grams per gallon. 1 in Veg and 1.5 in flower.
