She's looking much happier bro and top marks for the training,she will have loads of heads.
I dont really think its too much nutes (only my opinion), dont know about that rhizotronic..all i can say is i used canna terra professional plus and added guano & rock flour to the soil (on photoperiod strain) because i found the canna soil best to use as a medium to put bio nutes in an cut my own mix (i guess ur soil is pretty much the same but u can check the stats at the canna website) and then i added some stinging nettle liquid manure every to every second watering with tap water (left standing for min.24h).
To make it u have to use fresh stinging nettle like 2/3rds of a bucket and then fill up with water (u can chop up the nettle to make it go little quicker) and leave it standing in a warm, best sunny spot for at least a week, mix it around and when it really getting stinky and u have bubbles the love portion it ready.
In my Opinion self made fertilizer is superior in cost (this liquid manure will cost u 0$) and brings up the really best,
may this helps to get your plant/s get as healthy as can be.
And by the way it makes the weed taste incredible good&strong
Mix the Liquid Manure like 1:10 with water for regular use if u think they need it stronger u can double or triple as well. But always check the reaction
It looks now Bio Canna line works great, I only need to understand what was wrong at first stage of this plant life. Only what I did different form Canna instruction is adjusting PH level with lemon. They recommend not to adjust either PH nor EC when using bio canna line. I have plenty of their earth and nutes so I will use them first, for next few grows, giving me an opportunity to learn to use them on best possible ways. But definitely interested in learning to use home made organic food, tea and compost, in near future hopefully.@Vlada I realy share your opinion! Glad you liked my advise. If you want to know something or diskuss any opinion about organic/biological growing (wich i never made before, i take the raw material an vaporise) or u may want to share knowledge just message me. I try to make something in a way similar to yours, to help my grandparents who take tons of medicine and in my opinion its not helping but poisoning them.
