Is this light burn?

Got some small 65watt leds for my mother plants, just wondering if this is light burn or some sort of deficiency .

coco with 2ml per liter canna and 1ml per liter cal mag and doing some folier spray. 5.8 ph

Looks more like nute burn. Light burn is going to affect the top growth only and you got that all over. Stop the foliar feeding. No need for that and it isn't helping.

As you're in coco I'd flush some plain, preferably RO, water thru it and feed no more than half the max your nutes say. Up your calmag tho as coco likes lots of that. Your lights aren't strong enough to let the plants use more than lower level nutes so it builds up in the leaves and starts burning them.

Good luck!

:peace:

As explained, your light is not sufficient enough for transpiration of the nutrients your giving them and it's burning them up. Flush your coco with JUST water and then do no more than half strength nutrient.
Also, get a better light ASAP.

What coco is it?

I personally wouldn't add to much calmag on top of canna coco nutrients.(if that's what your using) Least not more than you have already.
Doesn't look like any sort of light burn or stress I have seen.
I wouldn't be foliar spraying nutrients or calmag either. They are not meant for foliar feeding.
Calibrate your ph pen if your using one, flush and feed 1.5ml per litre from now on.

Plant has a look of late N tox.

I had these same issues when i tried using a foliar spray in previous grows, i dont even bother with them anymore.. maybe this could be the variable?

does every nutrient suck? it seems like your on every thread telling someone their nutes suck. every set of nutrients has its own finesse aswell as each strain.. just because someone hasnt figured it out yet dosent mean the nutes are trash..

There's a lot of nutrients that are really better off never being used to grow Cannabis.

Im was being decisive...my bad...i know a dude running remo actually, he loves it.

I dont have much expierecne with it, but if its pH swing is so drastic. Something is wrong.

Id start by mixing a solution of each part (idk if theirs more then one part) separately then seeing if any individual part wont stabalize while in solution.

When mixed and in rez keeping the solution moving to prevent separation with a 1min on 4min off timer tona water pump to move water is nice.

Also try a pH buffer like a hydroponic humic/fulvic mix(like full power). Or a hydroponic safe kelp like herbs n kelp

Organic elements will help bond any loose hydronium and hydroxide's that react with minors to cause pH swing

I just looked it up..velo has a bit of everything in it, should have a stabilizing affect.

Ill ask my buddy what he does, hard to armchair it without more data

Do you use RO water?

the water source could be the variable i have been looking for, im using a mixture of store bought dist and RO water just started running it this week but i was having ph issue before the water change.. the mixture is actually more stable than just straight dist water.. im looking to completely cut out store bought shit coming from different states..

So i just talked to my buddy he says he adjusts daily ...uses same line.

Not for me. Personally but he likes it.

My rez stays the same pH for 5 days or so..tbh i havent seen any deift before i go through it all.

I run AN pH Perfect nutes with RO water only when I do DWC and never even think about the pH. Same when I use it in soilless ProMix HP.

I've been messing with organics in the HP and it never seems to work out well so will go back to straight HP and nutes.

Lockout seems likely from low PH.
Adjusting PH to 5.8 is on the low end for coco, might want to try 6.2.
Drops should be used to back up a PH pen especially cheap pens.
Check the roots for rot.
