I just went by the bottle instructions mate it says 1/4 tsp per gallon and i have just over 4 gallon of liquid in there.
Ill try and get a decent close up picture of this plant with the funny markings on the leaves, i have done a bit of research and i think it may be mag deficency. Its not just on the tips there are slight markings on the main parts of the leaves also. They arent lagging or anything so i have lowered ph again and ill keep ay eye on them. I have noticed though that the affected plant still hasnt got a root coming out of the basket where the other one i have which is 24 hours behind it has?
My ph seems to creep up about 0.5 every 2 days so from now on im gonna use a starting ph of 5.2 and hopefully even with a rise it will stay within range for a few days.
The veg nuites lowered my ph slightly when i added them but i have got that stable at 5.9 now and wanting to follow the canna guide to the letter i added a tiny bit more of each nuit and got the ec bang on 1.5
