COCO COIR Low nitrogen?

[HighLife]

Thinking I have a low nitrogen issue. pH at soil and water is fine already looked into that. Did a flush yesterday. Strain is fat Banana auto. Growing in coco with FF trio nutes. Fabric pots. She's about three months old or so. Mid flower. Buds are starting to fatten up. She's been this lime green color from the go. Not sure why I'm trying to solve it now. Do you think it's nitrogen deficiency or something else? Best way to solve that? Should I look for N only liquid? Blood meal top dressing?

Much thx! Help appreciated.

BTW... At mid flower is it even necessary to adjust for nitrogen?

Personally, I would be using hardly any nitrogen at the stage your buds are at, to me the way the tips are burnt and turning up look like it's getting "hot" either too much nutes, too much light or high temperature.
It's fairly normal for leaves to start yellowing at this point as the plant sucks out the carbohydrates and energy stored in the leaves but I think there's another issue here.You could try some cal-mag to help her repair but not continulessly.
I've also heard that you can trim the burnt edges off the leaves and that helps save what's left of them but I haven't put it into practice yet.

Looks like its expressing itself. All the phenome charisitics it has will display from now until the last day. If the neutrient it needs anit in the pot, the flower will take from the leaves. And so the hunt for the missing nute chase is on. If you havent missed your window you can feed bloom nutes to her.

What is the pH going in? Have you been using calmag?

[HighLife]

I vary ph from 5.8 to 6.2, every other water I go low/high. Only use calmag when pH is above 6, so every other watering. I'm watering about a gallon, maybe little less, every two days. I've read conflicting information on trying to adjust medium pH based on run off water so I've only focused on water ph. I flush once every couple weeks with water and no nutes. This particular plant has been this color since day one so maybe that's just how she is?? It's a heavy indica hybrid and she's growing the slowest of the 4 strains I'm growing at the moment.

I noticed nute burn on the tips as well. Tried to push her I guess a little too hard so I've backed off the nute strength a bit.

That all sounds pretty good to me... Definitely could just be a sensitive girl, I once grew a Durban poison next to a OG Kush in DWC at the same time under the same light same resivour same everything and the DP finished perfect yet the OG went yellow.

The color you are seeing is part of the cultivars phenotype. There are probably 3-6 different ones from the same genotype. I see a lot of yellowing during the flowering stage with the Banana Genotype.

Looks more sativa than indica which could explain some of the lighter color.

You got some pretty bad nute burn in spots.

Just keep em going with bud nutes.

I would stabilize pH at 5.8, add calmag with every feeding, add some bloom nutes, and reduce the lights if the burn gets worse. They are coming into the fade soon, they are what they are. They will never look pretty at this point, but that doesn't matter so long as the buds keep growing, carry on. Sometimes the genetics just say I'm not going to follow the crowd.
