Help my favorite strain's mom is sick

[Learningtogrowbc]

Hello there, first time poster here.

My room has a/c, humidity is low around 40%
I feed and water at 6.5 ph(liquid test)
I have been feeding with gia green dry amendments mixed into a tea that I aerate and then filter.
Using water that I aerate and wait atleast 24 hours to de-chloronate.
Feed 2 feedings at 1200ppm and then water, repeat.
In 50% perlite 50% coco coir.
I spray with neem once weekly for pests prevention.
I include cal mag and root promoter with feedings.
All organic.
Veg room is under hortilux blue mh.
Using yeast method of introducing c02.


Please help, this is the last of this pheno. What am I doing wrong?

Thank you in advance for all your help. Read the forum often, just never signed up before.

How old is the mom?
Looks like nitrogen def to me lower leaves all yellow and the whole plant is light lime green

 

[Learningtogrowbc]

1 year

Part of the plant is dark green.

That could very well be a nitrogen def. I see other plants are yellowing as well.

If she is a year old how long has it been since u gave her a proper flush to get rid of built up salts in the medium.
I c that u r putting nitrogen in but if the plant cant take it up from build up u get a lock out so to speak

The plant has been flushed and has been repotted as recently a 1 month ago.

You need to pH for hydro. Adjust to 5.8.

Good eye vg! I completely missed that

I see that you need to water and feed heavier . And you should recover.

5.7 to 6.0 for coco and the neem oil clogs the stomata which slows down transpiration. The a/c will slow it down too. But Virgin Ground nailed it your not uptaking nitro to grow due to ph lockout

I’d raise the humidity some too for veg.
If your temp is 70-80F, you should be between 65-75%.

Good reference.

Thank you. I put her back in a smaller pot, changed humidity and changed ph to 6. So far she has stopped declining. No significant t growth yet. Might take some time for turning around.

That feeds pretty strong too mate 1200ppm is a lot. If your letting the Coco dry out at all it's probably well into the thousands in the pot.
The guys are right about the pH but thought I'd point that out aswell. I'd be using about 300ppm for plants that size.
