If the lower leaves starts to turn yellow, they are not receiving enough Nitrogen. Use nutrients suited for the vegetative phase, such as Canna Vega along with Cannazym and rhizotonic. Good luck with your project!

Please help. Last plant died exactly like this. Yellowing drying leaves from the bottom on all fan leaves while shoots get stunted / eventually affected.Transp recently from 1g > 5g. Seemed ok at first day after (no wat) then leaves started rapidly yellowing / drooping. Tent is fairly small 40x40x120. Could it be the heat ? Also took out humidifier but still in same room tent vents. Is Canna Pro Plus watered between 5.8-6.2 ph ?5y ago

Yellowing in the top?What's with the yellowing in the top? Is it normal? It's in a very nice soil mixture and I've fertilized it with Osmocote, a popular slow release fertilizer: https://icl-sf.com/mx-es/products/ornamental_horticulture/osmocote-plus-standard-5-6-a903226-15-9-12/Week 5

Yellow leaves on the bottomMy cheese auto is getting yellow leaves at the bottom.
I'm not sure what's going on, it might be that it wanted more nutrients so I have added some nutes..
but I'm not sure.
it seems like the yellowing has stopped but I want to be sure,
since its an auto I don't want to stress iWeek 5
