Berry Ryder yellow leaves

[Towlie]

Hi thanks for looking I have looked through the self diogose threads and it looks like my berry Ryder has a nitrogen deficiencie

the yellow leaves started from the bottom of the plant the older leaves have died off thought it was natural but soon as one set dies another set of leaves start to fade

I have tried flushing her I have started to add some grow nutes to her feed and it's still not helping starting to worrie now the top of the plant is perfect but the older lower leaves are slowly

Any ideas on what it could be or how I can solve this she's getting
2 litre of 6.5ph water with
2.5ml biobizz bloom
2.5ml biobizz topmax
2ml Calmag
Just added 1.5ml grow

This is my first grow with air pots and the pots seem to be drying out fast could it be under feeding is she eating her self I have tried everything and have spent many hours researching online and it all comes back to a N deficiencie could use some expert advice

 

[oldcoot]

is that under led's, are you using cal/ mag ?
never grew in an airpot but looks like your growing with led's

 

[Towlie]

Yeah it's a under a marshydro with a few CFL s for side lighting should I add more cal mag

 

[oldcoot]

Possibly. My calmag says 1 tsp per gallon. I have a seven gallon tub.
At that size plant i would use about 4 or 5 tsp to my tub.
Hope that helps.

Hey mate how old is this plant ? What medium is she growing in?

 

[Towlie]

@oldcoot i will up the cal mag I have only been giving her 2ml will double the dose see if it makes a difference

@sour.b shes in John inns waste land and she's 45 days old today from the day she showed her first leaves it's a 50% soil 25% perlite 25% vermiculite mix

 

[sour.b]

Is the soil already fertilized or is it a light mix ?

 

[oldcoot]

How many ml in a tsp ? If 2 ml is a tsp, then i would go with at least 4 tsp.
Oh just saw your in soil. That might make a difference. I grow dwc.
Soil grower might help you better.
Thought u were just perlite and wermiculite.
Still think you need more calmag though.
Good luck.

....looks like it, but I'll need a whole plant pic as well to see if other things are involved,....

 

[Towlie]

@sour.b its a seedling light mix no nutes needed for the first 3 week

@oldcoot a tsp is 5ml i have up the cal mag to 5ml then will add more if needed
