Plant Problems: Please Help Me

[home.grower]

Hello

I'm @ Day 34 in bloom. The strain is AK47. The affected plant is in a 15L pot.

https://www.rollitup.org/marijuana-pics/index.php?n=10458

This plant got a little bit damaged by a 125W envirolite around one and a half months ago when she was in veg. Over night she grew, and the following day her leaves were caressing the bulb. I had to end that relationship!

That was quite a while back and wasn't prolonged as it was sorted within 24-48 hours of it occurring.

Now she's in full bloom as we approach the closure of week 5. Can anyone explain the problem with her?

https://www.rollitup.org/marijuana-pics/index.php?n=10459

Her top few leaves have been very light green, then yellowing for quite some time. I thought she may have recovered over time. Unfortunately, after having quite a stable defect, as time has gone on the leaves are now looking quite seriously in need of attention.

Her Top is kinda albino. She displays a lot of yellow characteristics. Yellowing leaves. Yellowing Calyx development. I hope she isn't rotting at the head. Any suggestions appreciated and I'll try to answer any queries about her upbringing.

what kind of light are you using now and how far away? looks fried to me!

I think it's normal for your leaves to start looking pretty sickly when flowering is in full effect, especially towards the end of the grow.

A professional opinion might not be a bad idea....but I think you're doing fine honestly...things look OK

You think those pics look ok? I am no expert at all but from the pics there def seems to be an issue. Maybe a simple fix but you still got a ways to go. I understand your concerns.

 

[jomal206]

Yes I honestly think the plant is OK......lots of pics I've seen of plants late into flowering look like that.....

Once again, it might not be a bad idea to get someone in here to really knows what they're talking about...but that's my opinion

The plant is focused on developing those buds, it's sucking all the nutrients out of the leaves and leaving them like that

Are you flushing/using molasses or anything right now?

I am blooming using 2 x 600W hps in a 6" dia. cool tube, linked to a 8" RVK. The tube surface is currently 8" diagonal from the cola tip. But the pot do get moved about daily and I do try to ensure that the tops are not getting blasted with too much heat with the old hand-check.

I don't recall having the tops of the plants close enough, especially recently, to cause burn. They aren't crispy. Just very discolored. Ant it is only happening on the tallest plant.

Thanks for your reply...any more ideas?

I have 2 others of the same strain at the same phase in their cycle and they do not display the same characteristics, which I why I find it odd. They all get fed with the same nutes from the same mix in the same bucket.

I'll take another pic

Thanks for your reply

I get what you are saying, but whatever that is doesn't look like a nutrient lack in terms of bloom. It's kinda brown. I'm not an expert either, but I've never seen this in my garden before, not even when I was an amateur NFT dude (i had real problems then hahaha)..

Nope, I'm not flushing. I have been giving them food and food amendments from A.N.

Here are a few, bigger i hope, pics that detail the problem

I should really take the plant out from under the hps tint and get some daylight in there.

cheers

Ok, some knowledgeable source as broken the term 'Necrosis' to me.

The inform me that once a plant becomes burnt at anytime, leaves can become necrotic.

So I went to wiki and looked up those two words and it makes sense. I'm still unsure of what it can ultimately lead to though.

 

[home.grower]

Yes I honestly think the plant is OK

true, but for the wrong reason mate

that poor thing is having issues. it almost looks like it got water on it then the light intensified the water and burned the leaves. this happens when they get splashed accidentally with the lights on. maybe when you were watering you dripped on that plant trying to get to another plant. i was going to say nute burn until you said the others are doing fine. seems like if it's only one plant then it must be some type of injury.

Roger that good buddy. Someone says it's Necrosis caused from way back when the plants were in veg, which sounds plausible. But then again. There have been numerous sets of new leaves formed since then.

I'm about to cut them off any how. Someone else had now said that and decaying leaf matter on a flowering plant can cause buds to start decaying aka bud rot. Better for ma to be on the safe side of caution and remover them than waste precious medicine.

then you are watering them if you spary the leaves make sure there arent any bubbles cuz if you keep the bubbles on the plante what can happen is the bubble of water will act like a miror and turn your leaves yellow

I have 6 plants under 400W mh and 600 hps side by side . I am about 30" away , had them closer but I though it was burning them, it turned out it was with nutrents. I was not giving them half dose an my ph was up. do I keep them the same distant

Looks like physical burn from the light. Good news, it won't ruin anything just a little sacrafice. Had this happen previously early on in flowering, it eventually was over grown. Just keep a good eye and my opinion is you'll be in the clear.
