Any input please

[Airbone]

So this problem escalated quickly.
My Chemdawg started showing small brown spotting on the bigger fans.
I thought it was a slight lock out deficiency. So I gave it a flush 2 days ago and after it’s first feed after flush I have this now.
Yesterday was still slight spots.
Help!!!

The rainbow sherbet shows no signs of problem yet…
Just want to catch it before I do.

I am in a soil mix
Ph 6.5
Fox farms nutes and plenty of cal mag.

Have you checked your PH runoff after your flush?I had this problem on one of my plants last grow. The ph runoff was 5.5 probably the reason the calmag I was giving it wasn’t doing anything. My other three plants with the same care did not have the problem.
have you been giving it calmag along the way?

 

[Airbone]

No…
Damn it lol
I just rushed well assuming I had ppm build up or ph issues.
So I flushed it with ro @6.5.
Didn’t really get worse till I fed again after that.

 

[Airbone]

I feed with cal mag always cause I use ro.
I feed on one watering with cal mag and nutes.
Next time they dry up they get ro, cal mag and mammoth p.

 

[Airbone]

Always phd properly

I’m feeding with FF too and calmag and molasses during flower. I just started checking my output runoff PH since I had these problems. Noticed that I have to put PH 7.5 in or at least above 7.0 in in order to get 6-6.5 out. Haven’t had the problem since I’ve been checking it but don’t know that it won’t happen again. My nutes and cal mag do seem to be hitting the spot now tho. Hopefully someone here can help, just thought I’d tell you about my plant that did that. I called her Ms ugly it started in week 5 of flower and by harvest time the sugar leaves were covered in ugly. Oh btw, the bud smoked great, actually one of my favorites now that the ugly is trimmed off and cured

I will start checking my runoff more appreciate your help.
I saw your Ms ugly lol.
It happens right, looks like your killing it now.

it looks like a phosphorus deficiency

you might cut back on the cal mag and maybe add extra phosphorus

how late are you in flower?

Is it just at the top of the plant, or are the lower leaves like that as well?

 

[Airbone]

Mostly tops and big fans.
Lower still seems green but droopy!

 

[Airbone]

These look fine though…
Same feed same schedule everything the same.
