Hi everyone I have a problem I can’t seem to figure out. Getting brown leaf tips similar to a nute burn but only running .8/.9 ec. Humidity is 60/70% ph 5.9/6.2 room temp is 24 degrees. There growing like mad but this keeps happening across all of them some top leaves some bottom some middle. There in deep water culture undercurrent system. Only thing that’s been a little off is the water temp has climbed to 22 for a few days but is back at 18 now.

What's your PH? And, what's your water source?

It’s 5.9/6.2 and using tap water
OK...I think you just need to lower your PH to between 5.5 -5.8 and it should clear up...
What you have looks like a Calcium deficiency, especially since your temps & RH appear fine. Most common causes of a Cal deficiency would either be using R/O water and NOT adding a Cal-Mag supplement, or incorrect PH.
You can see by the below chart that, in hydro, Ca starts getting locked out at 5.8:
I hope that helps!
I'm not a hydro guy,but I'll give this a bump so someone who
is may see it and give you some pointers...

Looks like it needs some CalMag. Have you been giving it any?
Ec means nothing without knowing your nutes
What ya using
What strength
Any enzyme cleaners
Good bubbles
Any Goopies or crumbs in the bottom of yer buckets
Pics of entire plant is also good

Thanks every one. I will take full plant photo latter and put them up, I added cal mag yesterday just befor I posted and will lower the ph today also. The food I use is green haze a/b and at the moment there 3 weeks into veg in 55 litre bucket loads of bubbles. Will also take photo of all nutes being used and roots. Thanks again for taking time to have a look everyone

You used them in dwc and they stayed pH perfect? Even with scillica?
Surely not?

I'm in for nose too mate. More eyes the better. I'll wait for your update before guessing anything though.

Ahh that makes more sense mate lol. I've heard there are pH perfect hydro nutes but not something id ever put my faith in. Too many variables in hydrothat effect it.

No worries bud, I'm a bit lost on this one to be honest so I'm hoping a full plant shot will enlighten me. Couple things don't add up but I'll wait for the pic so I don't confuse things with bad advice.
