I'd appreciate any insight.

Did those leaves come directly in contact with the soil layer or something? Kinda what it looks like..

 

[BL4ZE20]

I don't think so, it's possible some of the lowest one's tips could have got in the soil but they're all dropped off and dead now. The one's doing it now are nowhere near the soil level.

A 22" plant in a 1.5 gal container? Even though you are in early flowering Transplanting would be the best option. 3+ gal would be great.

No nutes? why? FFOF + guano is not amended enough to carry plants all the way through flowering. Get some known flowering ferts such as earth juice bloom, tiger bloom, biobizz ect. ect. ect... pretty much anything with high P, K, Ca, Mg and low N, but at this phase of flowering you will need a pinch of N.

Could you take some pics of the whole plant/setup so we can get a better idea of what's going on?

some added high phosphorous bat guano

this would be the problem. It is burning those plants.

You need to be real careful mixing soil. too much additives, and you burn your plants bad and you can't flush it out fast enough. The other issue is uneven distribution of ferts in the soil. Too much in part of the soil and it fries the plants you put in it.

I now use straight coco and give all liquid food because of an incident with too hot cocosoil and an entire garden almost lost.....

 

[BL4ZE20]

I have to use small containers because of my cab size. I've just been letting her feed off the soil but I do have liquid ferts if she needs them.

Heady pete - are you sure it's the bat guano? I have another satori that I amended with the same guano and she's not having these problems.

I'll try and get some more pictures for you guys it's lights off for now.

are the stems bendy and pliable like they normally would be.? or more hard like and stiff to squeeze. looks like a crispy critter to me. good ole plain jane wtaer is your friend in this case, imo. with a correct ph of course maybe 6.2 is ideal in your case. g/l

 

[BL4ZE20]

Since I can't seem to find anything else it'd be i'm thinking headypete must be right. It must be the bat guano I must of somehow either put to much in this girls pot or have a hot spot. I'm guessing my only option is to give her a good flush?

 

[blowwhole]

Is this a purple strain? Those leaf stems are very purple.

 

[HeadyPete]

Hi sorry I have been away....as you said, hot spots can differ from pot to pot, and different strains can take different doses.

Usually with dry amendments you can't flush them out and a transplant into new soil/media is required.

If they aren't getting worse than they were than your plants have grown into the dose...
