Noticed these yellow dots two days ago. It is now 1 day until it has been 4 weeks of veg. Two days ago I have it it’s first does of nutrients, Miracle-Gro 20-20-20 plant food. Just gave it another shot today. Is there anything else I should do to keep the plant healthy? Thanks

I agree with PiusWaxis here and Ezzjaybruh... it looks pretty overfed yet you have no information on the nutes you're giving her, if any... but what the little dots are showing is a calcium deficiency - which MAY be caused by a nitrogen toxicity (plants do look very dark green) or a pH that's not at a good level (again, no information on that in your diary) - the pH needs to be maintained between 6.0 and 6.5 for a healthy grow in soil. If you can't fix the situation that caused the deficiency, it won't help even if you throw a whole bottle of calmag at her... she won't be able to get at it. But all of this may not be anything to even try to do something about because you've topped a plant that hates anything more stressful than LST. While some are able to successfully top an autoflower, they can do it because they know how long the veg period is for the strain they're growing... but if you don't know that and don't know WHEN it's going to go into flower, you can't plan on providing it with sufficient time to recover and it's all over before it even starts. MOST autoflowers will go into pre-flower between week 3 and week 4 ... I hope yours isn't one of them... Good luck... and p.s... if you think you've got fungus issues, you would need to do a little more than just trim off the leaves... fungus spores go everywhere, they don't just stay on a leaf that can be tossed in the bin..

Thank you for all your responses. For a first grow there is a lot I don’t know, but I’m definitely here to learn and I think all your feedback will come in handy when moving forward. I’ll try my best to accommodate for this plant, and will keep all of this info in mind when trying future grows.

Yeah that soil is not great for canna. Not sure if you’re feeding anything but it looks to be overfed.. too much N it seems.

To the eye it seems that the plant is overnourished, the leaves are very swollen and very dark, I advise you to put only water with adjusted pH from next time for a week, everything should return to normal
