I have a big, bushy auto northern lights growing in a 5 gal bubble bucket and it is in the early middle stages of flowering (I think).
It was sprouted on dec 1 but it's quite a slow grower, and looks like it has quite some time to go.
I have been mixing up its nutes following the canna guide for aqua nutes for normal feeding, but at about 75% strength, using all of the products listed and also a bit of cal-mag.
When the buckets get changed, the nutes are about pH 5.6/1100ppm/EC1.9, and then it drops gradually over the next 4 days and stabilizes at about 550ppm/EC1.0. But with my water, the numbers are actually 260ppm/ec0.6 (My tap water is pH 7.4/EC 0.4/290ppm)
The pH ranges around 5.6-6.1 and I use water at about pH 5.7 to top up each day to just below the mesh pot.
I keep on just adding water to top up even after the nute readings bottom out for about 7-8 days before switching buckets with new nutes.
Am I feeding it enough?
I noticed that the plant was looking a little yellow, so should I switch the buckets and give it fresh nutes when it has sucked out the nutes?
Should I simply add fresh nutes to the old bucket periodically?
Should I aim to keep the nute levels constant by adding nutes and water each top up and then doing a bucket change every 8 to 10 days to deal with any buildup of unused nutes, etc.?
Here are a couple of pics. Thanks for any advice.
