Mother plant/clones look off?

Hey everyone, I’ve got some genetics that I love and am trying to keep around. The problem is the mother just is t healthy anymore and the clones look similar.
They’re just not vibrant, the nodes are brown and and the stems seem kinda woody. What’s the deal?

does anyone know what this about? Not sure I want to invest the time in flowering them if the clones are off?

straight coco and they all root out. It will the plant recover to vibrant?

Hi, for anyone to help you'll need to supply information about your grow like the nutrients, how often you feed, the environment temps and humidity etc.

I wouldn't write that plant off it only needs a few weeks tlc.

Sorry lack of info, here some.

Straight coco
Athena blended line normally feed daily (there’s been a couple times I missed a watering and they looked bad after but popped back kinda)
Environment is around 74 degrees consistently, humidity around 60%, no added c02, under full spectrum led. 18/6 cycle

Are you pH-ing your water/nutrient solution?

Get a General Hydroponics pH test kit -the green liquid. Do NOT trust the readout of cheap pH pens/meters. They usually don't get calibrated properly, etc.

Using the General Hydroponics test drops is MUCH more accurate, in my opinion.....unless you happen to be color blind. Look for that green olive color for the ideal pH.

Slurry test:
Take a TBSP of your coco mix and mix it with a cup of DISTILLED water and wait for it to settle. Then take a bit of the clear liquid and test it. If it's low or high, then adjust your fertigation pH accordingly.

Runoff test:

When you water/fertilize, save a bit of the runoff water and test it. Adjust accordingly.

*Lots of times, coco isn't rinsed properly and has a lot of salt in it. It can cause crazy pH extremes. Even if you've been using it forever, you can get batches that are way different pH-wise.
