the strain in exodus cheese ( skunk x uk cheese), ive noticed some yellowing on the leaves, as well as this one really bad leaf... there are 4 plants all same strain. they r in ffof soil, fed w ro water w canazym, organic thrivealive, superthrive, and general organics bioroot. just yesterday i transplanted them from small 4inch pots to 3 gal pots... so im assuming maybe some stress. but they r almost 3 weeks old, so maybe they needed more grow nutrients w more nitrogen, cus they were in such small pots, they didnt have too much soil in there to draw nitrogen from. they were not root bound yet, but they did grow real bushy cus they were topped at first week... i sprayed them w some safer 3in1 in case it is rust or fungus... i have seabird guano rich in nitrogen i mat throw on top of soil, while maybe adding a lil grow nutrients. but like i said they were just repotted into 3gal pots w fox farms ocean forest... it doesnt look like nute burn, so im thinking its low in nitrogen... but i dont want anymore spotty or rusty leaves pooping up... thanks for the help...
