Help!! yellow/orange leaf tips

I'm currently flowering my Turbo Jack, 1 month from seed, everything has been going great so far but the past three days I noticed a yellow/orange spot on two leaves, I thought maybe one of my lights touched it and burned it but it has gotten worse, just checked on her today and it looks a little more serious, as If it is spreading on those same two leaves, any help would be greatly appreciated. Hope she's ok.

I haven't given any nutrients, I just planted her straight into FF ocean forest soil, I have been just using Aquafina bottled water, I water once every two days, I get decent run off.. Could it be a PH issue? I haven't invested in a PH tester yet

Looks like a K deficiency to me. That could be down to over fertilisation, but if you haven't fed then it seems unlikely. Maybe the soil is just running out of K. MJ uses a lot of it. Now might be a time to add some bloom nutes. K deficiency usually starts at the top of the plant and works its way rapidly down. When it is caused through over fert (as salts prevent K transport) the whole plant can be pHucked ina few days... with under fert the process is more gradual. But K is an essential nutrient... best feed some.

Any suggestions on what it could be?

Thank you for your advice, I don't have time to order anything online as u can tell, it would take roughly 5-7 days to get here so I need a quick solution, walmart, tractor supply, lowes are my only options. Any suggestions?

Yeah anything will do. They're just plants.

Make sure it's a bloom oriented nute though. Something high in P and K... low in N.

yes.....I think it could be.........
WHY is your POT........ HALF-EMPTY!?!?

pot up to 5 gallon bucket, and put 4.897657 gallons of soil in it! water in.

it started off full but over time it has went down.. weird huh?

Im afraid to transplant this far into the grow, from what ive read autos do not like to be transplanted

your roots are are.......scrunched up like, inna tight spot. you feed them.....itsa too much, but then. it getsa flushed out, cause itsa so smalla volume.

more medium, less feeds, greater stability of grow.......imo.

Ok that makes sense, I guess for now ill just start will a really low dose of bloom nutrients, or should I wait til my PH tester arrives? I just ordered a digital tester, and bloom nutrients but im afraid it wont make it here in time..

never grew them.

try'n find ya some auto help..........

Your yield will be affected by a smaller volume for root growth but nutrient uptake won't be affected. I've grown deep water through to full harvest in a 500ml pot before... also grown shallow water (a shared SoG) in 2" of water.

You can also go overkill on the medium.

You don't need to test for pH in soil. I haven't tested for pH in several years now and I grow in coco.

no.....I like it. weak feeds with every water, but let it dry out between. maybe a pinch of minerals watered in, too.

Really? So you think ill be ok not testing? Even when mixing the bloom nutes?

Considering I JUST ordered a tester and solution..

I probably spoke too soon. It depends on the quality of your water. You may need a pH meter.

salt-poisoning isn't easy in a container? let alone an inappropriately small one? that doesn't quite jibe with my experience. he's not doing a bottom-leach/water. just straight up soil, I believe. Dell.....wherever he is.........grew unbelievable gear in cups.......thimbles! I dare say. he also bottom-fed/leached/watered. but it was a little voodoo, and not a good style for non-expert growers. these young guys should be using plenty of medium, to provide buffer/stability to their grows. they can experiment down, once deft growers. imo
