Whole plant has turned yellow

Hey guys I am a first time grower with 3 outdoor Indica plants (Unknown strain) in 15L containers I’m 5 weeks into flower and my buds don’t seem to be growing a hell of a lot and over the last couple of days one of the 3 plants is almost completely yellow. I water regularly when soil is dry but I haven’t used any nutrients whatsoever (guessing this is my problem) we are in isolation here currently so hard to get my hands on some nutrients but is it too late or should I try get something to get rid of the yellowing? Cheers

Feel the same way mate don’t worry

Well, since you've provided no pictures at all, we can only guess.

My guess is Nitrogen deficiency, but since you're not feeding anything, other deficiencies are going to quickly follow, so fixing just the N problem is only delaying the inevitable anyway.

You need proper nutrients for the plants. There's no way around that.

Yeah ok cheers for clearing that up hope these photos help. They have gone quite well up until this point I will try get some food ASAP.

You need to feed them, and honestly, I think it may have outgrown the pot as well. I’m not sure if transplanting it is a good idea because you are flowering.

In any case I would wait to see what some people with more experience have to say, but it looks hungry and cramped.

She is most definitely hungry..not too much nitrogen..even if it takes a couple of feedings to get her color back, better than a sudden overfeed at once.
Good luck op

Cool cheers for the advice guys much appreciated

Now that pics have been added, I can see, and agree with the fact that the pots are likely quite a bit too small for plants that size.

Perhaps digging holes and burying them in the yard may provide just enough nutrition for the plants until you can put some real feed on them.

So I’ve gone and brought this I asked for something high in nitrogen and this is what I got obviously says for tomato’s but I’m sure it will work? it says 7mls per litre should I feed this every time I water now or every second time etc? Cheers

That really shouldn't be too bad, I have seen much larger in smaller...not mine to be clear lol.
OP, can you add a top dress of new soil? You can cut a rigid material strip( plastic, cardboard) to temporarily increase the height of your pot.
Just a thought, until said nutrient issue can be addressed?

No op..start feed at half that dosage, even less if wanted. See how she reacts, then adjust as required.

Yep ok done the half recommended doesage and I’ve topped all plants up with a fresh layer of soil, before I added the soil the old soil was quite firm and dense, is that another indication that my pot size is too small?

do you you have perlite in your soil mixture? if not, your soil compacts and its hard for the roots to get oxygen.

Not too sure man it doesn’t say anywhere on it but this is it

Ok op do you have any stakes you would use as supports? Bamboo?
Use something with a rounded end, and poke holes throughout medium, dto the bottom. Be mindful around centre rootmass, careful.
Will not hurt anything.
How is drainage in bottom? Good drainage is a must in pots...side aeration helps greatly.
Good luck op.

Drainage is good I think anyway, water still passes through, not quite sure on the stakes for the supports what do you mean by that? Cheers

You've flushed out all the nutrients. Your basically growing in coco now. next time transplant into new soil before flower

Hello...many stake their plants if grown tall to help support branching once heavy with Bud. You could use one to pierce the medium, thusly making more aerated and water accepting.
