Is this some sort of burn?

[Brettman]

I’m like 99% I didn’t spill anything on the leaves. Anyone know what this could be ? Literally happened over night.

It looks like what happens when you over do it with bloom booster

 

[Brettman]

Huh weird, i gave that plant nutes for the first time a few days ago , I gave it veg nutes @ 50% strength.

Not all plants like to be fed
I guess you should cut it in half

 

[Brettman]

Yeah true. This is my 3rd time running this same cut and I can’t keep it green. Goes extremely yellow at like 5-6 weeks of flower. So I thought I’d give it a little nitrogen to get through the stretch.

No it doesnt actually. When you overfeed you get burnt tips as a start, and it doesnt show up that soon unless your in hydro.

Anything change overnight? Looks like burning from contact with nutes then scorched by light as its located in different areas of the leaves, if it was overfeeding you would see it on the newest growth first. What are you using for light and how far away?

 

[Brettman]

Blurple about 8-10 inches away. Yeah one thing did change, it went from cfls in veg to led in the flower cabinet.

PH too low

 

[Brettman]

Its been about 4-5 days since I watered. Should I give it a good flush ??

 

[Brettman]

It’s in MG organic potting soil. I still have some fungus gnats but they’re not too bad.

I would

 

[Warden_Genetics]

Looks like water or chemical burn to me.. lights on when leaves get wet?

 

[Brettman]

Hey Warden, no I never wet the leaves. I don’t even mist my clones.

 

[westcoast420]

Are you able to raise the light up?

 

[Brettman]

Are you able to raise the light up?

Yes I could. Why should I do that ?

 

[0420Waldi0]

I read its a calcium deficiency. I ordered cal-mag so I'll be back with news

 

[westcoast420]

Yes I could. Why should I do that ?

Because it looks like hot spots, and if the only thing you changed was the light that would be the most likely culprit. Do you have good air movement over the canopy too?

 

[Brettman]

Yep I got lots of air flow. I moved it up to 12-14 inches.

You look a little over watered and short on Mg. To answer the question that you're 99% sure you didn't do (spill nutrient on them), snip off the discolored leaves and see if more appear. That will tell you what to do next. And the change from cfls to an led most likely took the plants by surprise, so be patient with them.
