Is This Light Burn? Or Somthing Else?

Yo,

I am having only one issue. Everything is going perfectly. Temps, nutes, schedule, enviorment. I just noticed this small discoloration on some of the fan leaves. I am hoping someone has seen this before and knows what it is. I have alot more light then i need in the space i am using and i thought maybe it was light burn. Like i said the temps are fine due to air-cooled hood but i am running out of vertical space so the canopy is alittle close to the light. Thanks for the help! hopfully someone outthere has seen this before.

hm... not light burn bro

or at least i dont think.... ive seen it first hand, my plants as we speak actually lol

Doesn't look like lite burn, me either, get a 30 power magnifier, look for bugs.

def not bugs. infact from the back side of the leaves that are affeted, it looks like nothing is wrong. It looks like the problem is coming from the top of the leaves. if that makes sense (which is why i guessed burn) I am using a mild GH Recirculating Expert Program, so it shouldnt be any sort of def. Thanks again for all your help. I know someone in RIU has seen this exact thing before

Looks like Epsom Salts overdose... Have you given your plants any ESalts? If so how often. I had the same problem about 2 weeks ago with mine. I just let my plant be and it healed.... I cut back on the salts and the nutes for a while.

Wheres Al B Fuct when you need him, he probably could have diagnosed the problem by now SIGH!

Almost everyday i wish AL were still here. You are completly right iloveit!

As far as the esalts Mawi, You are prob right. I have added esalts in my last change but the wierd thing is that i decreased the dose in this batch. I used only one tsp for a waterfarm res. which is about 2.5 gallons. I think that it might be a PH swing which could be explained by the fact i just got a new PH meter This could have been caused because the old PH meter was more "off" then i thought. The readings that it was give must have been way off By the look of the chart that Twistyman told me about, thats what it looks like to me I really hope that this is it and now that i got things back to where i want them, things should get better.

To be honest it is more a cosmetic problem at the moment just because it hasnt spread beyond 6 or so leaves. But i want to try and figure it out before it does become a problem. Thank you to everyone for your thoughts and help. it def made a difference Pe@ce
