They look much better!! Now you know the best way for hydroponic grow how to check for toxicity or deficiency, TDS meter is a great tool.

There was so many things that I missed that bit and wasn't sure what about all ppm readings. What about if I will try 1.5ml/L of a b as I was giving 1ml/L for last couple of weeks? That's why maybe purple tips on some leaves as they need bit more nutes?They should be 9 weeks plants to be ready so lets say 12 max and they are from 31 March.

You can try 1.5 but make sure not to go over 600 PPM, it's so easy to burn autos with nuts if you see something like this
, you will have to flush. But just to make it clear, your plants are not expereincing deficiency, all this spots from pH problems.
Phosphorus deficiency looks like this

Potassium like this

Multiple deficiency

Hiya,
Run off ph and ppm range for bushy but with almost no flowers plant is
6.0-6.2 ppm 155-170 in last 6 measuring.
Run off ph range for the one the right with much better flowers in last 6 measuring is 5.5-5.8 ppm 133-155
Nutrients going into the pots around 350-370ppm
What is wrong with the plant with barely visible flowers for so long? Could it flower properly later and still have chance for nice buds?
All the additives/boosters shoul20150528_182706.jpg d always be mixed with nutes only? Water needs to be always pure or boosters should go there as well before watering? Regards :-)

Hello ozzy, always have your pH at 5.8, and don't worry about run-off is slightly higher, it will stabilise itself. Mix all your additives and main NPK nutrients in the same solution.
Your plants are doing really well, so well done mate. Just follow your schedule and let them do their thing.

Hiya, what is going on that the plant on the right is flowering as it should and the other plant is still growing and flowers are small as few weeks ago? They have been growing in height equally and start to flower at the same time. Now Plant on the left is 15cm taller and was always a bit lighter in colour. Can be possible that this plant will be ready much later than the other one or decided to grow and not continue to develop better flowers or is wasted already? Please for advice. All the best Johny!!! Many thanks

Hello Ozzy, your plants don't get enough light. looks like plant on the right gets most of the lumen, this is why it has bigger flowers. The plant on the left is stretching up in search of more light. Swap the places of the plants and if you will see more improvement (on the left plant) and reduced progress (on the right plant) that would prove my theory. How ever I am quiet sure, this is the problem, as other than that they look healthy, but slightly over fertilised. Some one might advice you to decrease nitrogen and increase PK but I don't think this is the case, because canna coco is a reliable nutrients and on the top of that you are using PK.
