Here's a little update, about 1 week after switching them to 12/12.
They had their first shot of bloom nutes yesterday, still 50% of canna's schedule. I also added some calmag in the mix, guy at the grow shop said I shouldn't use it for more than 2 weeks into flowering.
I'm very happy with the way they look overall, some are very bushy... plants from my previous failures were about that size by the end of 12/12 for about the same time of vegging.
The topped ones are looking good..
I trashed the male. I'm still 80% sure 6/7 are females which would be an awesome ratio. The two topped plants are reacting differently, one has the biggest pistils and the other one hasn't shown sex yet.
I've got a cheap florasun 400w MH bulb from the grow shop this week, might run some AO's for my next run to see if there's any noticeable improvement over HPS for vegging.
You guys think that's it's a good thing to let them show slight signs of underwatering before watering again? I mean it's nice that when I finally water they seem to grow 1-2" overnight but I don't want to induce uneeded stress.
