Here you go M_C mate,
4x critical mass in soil only the one with problems nothing different to the others all been fed same.
Biobizz light mix soil
600w hps
1x1x2m grow tent
Temp lights on 25c-26c off 19c-21c
Rh 48-55%
A clip on fan and a tower fan blowing across top of plant the tower fan is on full setting no.3
Been getting 2ml oldtimers bloom for about 3 weeks now along with 0.6ml magne-cal+.
Thursday I picked up canna pk 13/14 and been getting fed that at 0.6ml along with the bloom and magne-cal+.
Getting fed every other day when pots are light, I mix up neuts in a 5 litre bottle when I feed them haven't been letting water sit 24 hour ? Water seems pretty decent here 😊 give a good shake before feeding.
get 2.5l each, always a bit of water coming out the bottom of pots.
And I think thats about it mate, any ideas ? have you had a phosphorus problem before ? 😉😊

Unless there is a reason that you are underfeeding your plants then the amount of feed is probably your issue....
You think that's the problem ? I've got slight burn on most of em ? that's a healthy one but got slight neut burn, that's why I'm not too sure 😕 not unless you mean the amount of feed I'm putting into them every other day 2.5l you think I should up that they are in 11l pots and like I said a bit of run off ? 😊😉

I'm just going by the Old Timer feed charts mate
2ml seemed a little shy to me...
Mc you are the messiah and I bow down to thy! Do you feel the bloom nutes may be a little heavy on the N?
They look really Green and with a few burnt tips.
Would there be any good reason to just use the PK boost instead of the bloom nutes?
My reasoning for this would be to eliminate the N in the bloom and just hit it with P + K.
I and I'm sure bracey really appreciate you lending a hand here, it's valuable learning for me😉

I hear what you say about the nitrogen and I tend to agree....
However, nitrogen is only one component in the feed & the lack of the other components are most likely to be the problem.
This is where it gets a little head scratching for me as a PK boost would seem the obvious answer.... but PK tends not to be organic so could cause its own set of problems by interfering with the microherd...
We could really do with an organic grower poking their head in here!

Lol 😂 appreciate any one popping into my threads and helping me out buddy expecially m_c though lol 😉
And I know I posted that in my diary the other day or a new thread mc to see if I should up them and someone said (could have been you) that basically not all plants are the same just go by how the plant looks and they look banging to me lol 😂 so just left as it was going by the slight burn thought it was fine just not feed stronger 😊😉

The trouble with boosting the Bloom feed is that it will also introduce more nitrogen, which we don't really want at his point
We could really do with an organic PK substitute such as
Using the above, we could also possibly reduce the amount of Bloom a little too, so we are basically mixing & matching the NPK values to our needs
