oh no its all going wrong !

[Mr Bloom]

Any ideas whats up with this guy's ?

Probably a nutrient lockout. What's your pH reading?

 

[Mr Bloom]

Im in soil and was not ph-ing what was going in as I assumed the soil would buffer it. noticed red stems and brown spots on lower fans so went out and bought a decent meter ... my runoff was 5 ! so I flushed her with .ph6.8 water and got runoff to 6.2 ... next morning the leaf in the pic had dark patches which have now gone yellowish

 

[Muddy]

The low pH was your problem. Red stems are often an indication that P is being locked out. How old are your plants, what have you been feeding them and at what strength?

 

[Mr Bloom]

she is 6 weeks from seed on Thursday ... was feeding half strength tomato feed at npk 4-4.5-8 but was told it was too strong for her so I have some atam bloom 2-2-4 and blackstrap mollases

 

[Muddy]

Probably finishing up veg at 6 weeks and going into full flowering. Those were the wrong nutrients for veg. Next time use something with a higher N value, like an 8,4,4 or something similar.

When they dried out and ready for their next feeding, I'd suggest 1/2 strength with the Atami, pHed to around 6.5. Capture and test the run off again and see where you're at.

 

[Mr Bloom]

Thanks muddy

 

[Mr Bloom]

Must have been the mollases that made the ph drop and all the p I had been adding with the tomatorite was not being used, hence the yellowing of the fan leaves as the plant steals the p to make its flowers with then when I buy a decent .ph meter and sort my .ph out the plant gets too much p and burns up... I obviously didn't get all the nutes out during my flush

 

[Mr Bloom]

it's funny how you can read read read and read up on a subject yet you only really learn anything when you actually have a problem

 

[Muddy]

Yep, nothing like first hand experience.
