Could someone help me identify this deficiency?
new grower and im not sure what it is. Just based off of other threads I would say either septoria, or calcium intake problems. This is also the only leaf on the plant like that. any help or advice is greatly appreciated. LMK if you guys need more info on the grow. Using fox farm trio. The pics make the spots look brown but they are definitely plan Yellow.
Could also be bacteria/mold? Don’t overwater. Upper leaves look good. If it spreads further I’d worry, but lower leaves get yanked later in the grow and are not a significant worry.

TY that is a leaf from her 2nd or 3rd node so it is an old one. shouldn’t really need to mess with ph or nutrients unless I see it spread right?.

Correct. Or see other problems. The first sets of leaves are fragile and “bruise” easily.
Really need pics under natural light to see the correct color!!

Could be you have spilled some nuts on leaves while feeding and could be nothing to worry about or possibly add a little calmag just to be sure

I agree, wouldn’t react to an issue on single leaf.

I think that’s very possible actually seeing as how they are trained so low. Here’s a pic currently during dark.
here’s my other plant just for fun. First time doing LST and I feel like it worked like a dream for this girl. I know youre not supposed to defoliate autoflowers but i feel like she might really need it in the coming weeks any advice I on that?. Thanks for all the help you guys are the best!

Plant looks a little droopy. Possibly overwatering, lack of oxygen at the roots. If you have a good light and the plant grows into bushes, I wouldn’t hesitate to cut my autos. Cutting could stress the plant and slow growth though.

I defoliate as little as possible. I use tuck and only pull the fans leaves around prime budding spots. I do Top, Find, and do LST on my autos without any problems.

Update.
Still just that one leaf. Thanks for all the advice guys! Been sticking with regular feeding schedule for foxfarm trio.

Selective removal of fan leaves to expose bud sites instead of removing them would be beneficial.
Thanks for the advice! I have been doing that as well. I’ve just studied up and and seen alot of growers picking off this super tiny growth at the bottom that wouldn’t lead to anything of substance, so that more energy goes to the top bud of each stem. I guess I’ll find out if it’s beneficial or not. It shouldn’t have stressed them out too much. They are already in week 2 day 2 of flower and I didn’t see those tiny things producing anything in the long run.

I agree, but anything that can be exposed by selective defoliation to become directly lighted should not be.

Quick question. I know that a nitrogen deficiency is normal towards the end of flowering,but is it normal or common for it to start early flower? Week 3 of flower and some of the smaller older leaves on the off shoots have turned a very pale yellow. Should I be concerned? ![IMG_20190331_165123|374x500]
(upload://hQR0o4rSK0mRtkOBG1aakLOlgQ1.jpeg) what strange to me is if you look at the tips of the leaves it also looks like they have a little bit of Nute burn. Is it possible to show signs of deficiency and burn at the same time?
