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 ?

Yellowing, burnt tips and edges
Hello fellow growers I noticed this happening rapidly after I top dressed. What kind of deficiency is this? Is this nutrient burn as well as a deficiency? Solely a Ph problem?. So far I’ve come up with maybe potassium deficiency and improper Ph when watering? Please help

Yellowing leaves.
Yooo! I have a few lower leaves starting to yellow I’m pretty sure its because the plant has switched all the energy to bud production so my question is, is it ok to defoliate the yellowing leaves at this point?

Deficiency?
I seem to be having slight yellowing of new growth and some brown spots coming up on the old. Anyone have any ideas what i need to give them? Is this a cal-mag issue or maybe nitrogen? Super newbie and just not sure, thanks! 👍
