Well things are coming along pretty smoothly. Still vegging the moms... hoping to get cuts by the end of the first week of august now, as long as theyre big enough to pull ~15 clones off of each strain.
I do have a couple of pics of what looks to be a mg deficiency, but I thought I would see what opinions the experienced eyes have. Just started to notice this forming on a few leaves of a few plants. maybe 10 leaves total on 3 plants out of all 24 plants. Looks like a few more are on the cusp of doing the same though, so any thoughts would be appreciated. This started perhaps 3 or 4 days ago. I should note that pH has been consistenly dropping .3 every day over the last four days. I notice mg doesnt become available until about 5.7-5.8 according to some charts i've been looking at, so this could make sense. pH went from 5.8 down to 5.5 the next day, then to 5.2 the next, then 4.9 today. I added pH up today to bring it back to a solid 6.1 to get more availability for the nutes lacking there. Hopefully this fixes the possible mg problem? When I added A+B on 22nd, I also added
Calimagic, so there should be mg in the mix.
Any idea why the pH is dropping ~.3 / day? On the canna nutrient info booklet it mentions that root secretions in veg tend to raise pH, while in flower they are more acidic and lower it. These plants are on a 20/4 light schedule though, vegging. Any ideas? The ppm having been fairly solid moving from 360 to 340, and now down to 320. Dropping about 10-20 ppm daily. Other than these few leaves, the plants look fairly healthy. The roots are booming as well - they're much whiter than the iphone makes them appear with the HPS's on. Cheers.
