Looks like nutrient issues, hungry or lockout. Please provide more details such as medium type like coco or soil and if soil what is in it or what brand is it. What have you been using as nutrients or dry amendments. Then check pH and ppm. Or, since you are on the last few miles close to the finish line if you have premium quality compost like home made EWC, top dress with a generous 2 inches and try to mix it gently with your hands in the top layer of your containers. Seems like you have enough space left there.
FF Ocean Forest & FF Happy Frog 50/50 mix. 3 gallon fabric pots. Cabinet grow. See attached nutrient pics. Avg. temp-75, avg. humidity 45%. 2 x 100w LEDs. Pot was sitting on AC Infinity self watering tray. I am thinking that I may have overwatered by watering from the top and the bottom. Pot feels heavier than it should to me. Maybe the overwatering is causing a nutrient issue(s)?
Sure could be with those details. Deficiencies sure can be ruled out. Hope she can finish in beauty and you'll like her smell!
I hate to be the person to say it, but it does look like C as l mag deficiency Sent from my iPhone using Tapatalk
Seen this white stuff on the base of the plant. You think it's southern blight or something else? Is there a way to treat this or no? And is it a gonner or no?
This looks like a decaying type of mold from here, probably in the family of saprophytic fungus. But with such a small plant, it could potentially harm it. Do you have other plants with her? If so, quarantine this one until mold is gone and you are sure she will make it. Place this plant in an other room, on a window still. Stop spraying water!! Drop humidity bellow 35%. Set a small fan to improve air circulation. Let the top soil dry out, the first inch should be dried before next watering. If you have a pantry full of grow stuff, nutrient and hydro product, you might have on hands Hydroguard. If you have hydroguard in hands, follow instructions at 2ml per gal, and use it for few next watering. If you don't have it, I would nor bother to get some, as this fungi is most likely harmless, unless this is a Very Very Special prized clone. In the future, make sure their is good air circulation, only water when the container is light (not easy with a seedling when trying to provide TLC! less is more sometimes!), top soil layer is dried, don't let water sit a the bottom of the saucer, and consider bottom watering.
OP have reported using Cal Mag BushDoctor already, and enough Cal Mag is found on tap water almost everywhere on the planet mate. I would be more concern about improper pH and lockout. As OP reports container being heavier than normal, these symptoms can well be causes by over watering. This is nice time to ask JimSwayne for a kind update!
Will do thank you! Idk if it'll be saved but will get it fresh air. I wish I knew autos were finicky to transplant before I put them in solo cups.
