I’m not really sure what this is

[3rd Monkey]

ph in veg... was probably a point or two higher then now.small system in veg 45 litres flower 100 litres.Water would drop a lot in veg ,top ups were 15 lires so a third.ph would be 6.3 ish for a day or two till i got it down to 5.8.flower is easier to keep below 6.

so ya maybe ill up it a bit after this week,thanks

Update when you can. I'm curious as to what ails it as well.

You'll need to dial in your pH for your grow type...the rest will take care of itself. Good luck.

Appears to be better or at least not spreading,also noticed that this maybe light related.affected leaves are only right under the light.Side branches are not showing these signs.Ive lifted the light a little.

I now have about 200 ppm more food also instead of calmag.

Mike you got to put up better pictures than that you put up a picture of a leaf tip and the other one wasn't in natural light, come on brother give us something to work with maybe somebody can help you out?

You said it was the middle and bottom and nothing up top.

Ya the ones on top right under the light only show a little tip burn and curled edges no spots.
There was one leaf in the shade that showed the spots but it appears to have stopped.

Light is on so hard to get a good pic,also to add what about high humidity?Change in weather here last week.I now have my dehumidifier running.Was 70% in there yesterday.

I've never seen humidity do that, high or low.

First pic bottom leaf. Second is the top.Both right under the light.

Can you do a whole plant pic? I see some heat stress.

Last night

Ahh, fuck those spots lol. Back off on the N.

They look real nice and I doubt that spotting is going to amount to shit. Should be a beautiful harvest.

LOL!Ya I dont think its a big concern.Was just wondering why.

I would chalk it up as leaves getting tired from being pushed... Being pushed very well I might add. Very nice job.

Get an LED flashlight and take some close-up pictures in that light.

Thanks,more to do with strain I think.
Ive lowered the N both in my nutes and no more calmag.With rdwc they just always stay real green.

So just an update ,seems to be spreading around more. Started more so under the light but now it’s starting all over.
So I was on a higher ph from 2 weeks ago. 6.1. Was at 5.8.
Saturday I added Epson about 200 ppm.still seeing if it helps.
So what I haven’t done.... add calmag or change ph to???
Heat stress is showing also. So not sure if that could be the causes.
Seams the spots show up first in the veins not on the leaf.
Some pics.

Out of curiosity, why did you cut the Ca out of your equation when you suspected it was short?...and it appears from your pics and description you were correct in that assumption.
