Yellow spots on cola leaves. HELP!

Yesterday morning I noticed these spots appearing on the leaves around the colas. They dont seem to be appearing on the rest of the plant, at least not yet. WHat could this be? Im thinking MG or calcium but I am not sure and I would like more opinions before I take action. Please help I am halway to harvest I would hate to lose my crop this close to the finish line.

Just flushed the plant after reading that it could be Mn deficiency due to overabundance of Mg in the soil. Will post results on sunday. Still could use some opinions.

Looks like a cal/mag deficiency, but not overabundance when the leaves taco up like that they are praying for more Mn. Add a tbsp of epsom salt in your water once or twice and it should stop the yellowing. Let me guess, kush plants?

To me it looks like a Calcium toxticity which is locking out Magnesium also. It could more related to a p.H imbalance. What is your p.H now of soil?

I dont have a pH meter. Well I do but it always jumps up and down so it might not be the most reliable. Also it MIGHT be Mg toxicity, because last weekend I put some epsom salts in the fert water. And the spotting started yesterday. It could have something to do with that.

It is mystery bag seed so there is always a chance it is in fact kush. But I doubt it. They are in their 4th week of flowering and the smell is basically non existant unless you literally smell the colas xD

no one?

So no one has honestly seen these spots before? Really? I have been looking all over the internet and I havnt found a single picture that looks like mine. Please help.

Looks like they right on the edge of nute burn. Nitrogen toxicity also. I would just give them plain water for a few rounds........

By any chance are you familiar with the Holiday Inn across from the airport in Isle Verde just outside San Juan? I help build it. And was on the Island during Hugo....I just love PR and its people. Road side food venders on Friday nights. Good food, great music and spectacular times.

Plants do not need all the P in you nutes. Not sure how/rates you are feeding them but you got the start of claw(N tox) and some spots I doubt are a calcium deficiency. They are getting a little burned IMO. Just water for a week or so and watch new growth. Bet they will be fine...

Its been a few years since I have been donw. But will for sure let you know if I make it down....maybe May 5th so we can walk backwards into the ocean! Good fucking times man...brings back very fond memories....

Hmm I guess its the nutes then. I have been feeding them full strenght for about a week and a half which is when the problems started. I will try feeding with water for a week then ease then back into the nutes but not at full strenght.

Last may 5th, me and my boys smoked under the pier. Good times.

Thats a good plan. Just remember those leaves that are already affected will remain damaged and may even get worse. Its the new growth you really want to pay attention too for the next couple of weeks......
