Noticed these copper colored spots show up on a few upper fan leaves, this plant is an auto flower at around 55 days since sprout. Happy to provide any details needed to help me better assess this issue; I appreciate any and all help/info provided :)

How do you heat the groom at nights man?
1
Light is 18/6 hours; it’s running at night it’s off 1pm-7pm. Do you think it could be something with heat? Just checked inside tent and temperature is around 78-80 Fahrenheit and 54% humidity with lights on.

Where is the heater located? Might be infront of front door and this plant is right behind the mylar?
1
There is no “heater” inside or near the front of the tent, do you think it’s to hot in there? It doesn’t feel hot enough where it’s uncomfortable in there, I just check right now and it’s 80 Fahrenheit

Oh that’s my hygrometer that’s at canopy level

Possibly potassium deficiency?

Was thinking the same. A small deficiency, but still heading that direction.
OP - are the stems of the plant softer than before by chance? They seem to be 'hanging down' a bit more?

Nah man. Prob not heat then...
What is ur setup like? Medium lights strain feed program
Natural lights pic of entire if possible, would b great
Thanks for your help :) Currently in a 3x3 with a 300W mars hydro(quantum board style), nature’s living soil mixed with fox farms strawberry fields/happy frog; it’s an auto flower of unknown strain, my feeding schedule is mainly water(sitting out for 24 hours to evaporate chlorine)however I’ve top dressed once with BAS craft nutrient blend, I top dress every two weeks or so with bokashi as well as use rootwise and also use build a bloom. I will take some pictures today of entire plant today as soon as lights turn on/watering, what do you suggest is the best way to post more photos?
It sounds like u know what ur doing man, im a coco grower so cant help with soil :(
Some folks here recomended a minor phosporus def... But ive only seen this coloring from heater too close to tent door... I never had any major deficiencies but calmag in quite a long time so cant vouch for that either man...
Hmmmmm the more I’m looking into phosphorus def I think this could be it >.< thanks much I really appreciate you commenting. I’ve always appreciated coco grows, god damn the plants you guys get are huge
Ur welcome bro, i know blackstrap molases at 1tblspn per gallon gives a nice boost of p and k, As well if leaves are dark green, u might wana drop your N levels, as i guess those stuff work the same for all mediums.
And yes plants get big fast, coco is all i know, even for veggies and spices, but now i have a small organic spices n veggies garden, i only give it humic and amino acids, and will soon add some organic N fertilizer.. its facinating to me... Its very green and fun, and a lot slower than coco.. gotta love the weekly/bi weekly watering lol... Easy peasy ;)
So i guess we all appreciate and want what we dont have, as id love to and probably will try to grow some organic weed :)
All the best mate, take care and stay safe
