bottom leaves yellowing

you know whats going on? my guess is that its nute deficiency, may i also add that shes kinda rootbound and a autoflower that is currently in that stage of bulking up the flower. what would you do?!?!?!?

i also notice its happening to only the eldest leaves and working its way up but only in order of age...

That said what week is it at? When does the breeder say it finishes? They usually show some nitrogen deficiency in flower but i wait for a little more bud development before i expect that

Look up 'ACE'. Autumn Color Effect.

Cannabis is a nitrogen lover. It craves it. As you know....Fertilizer for flowering has low levels of nitrogen. Veg ferts have higher levels of nitrogen.

As she puts on flowers, potassium and magnesium are what supports the flowers. Not much nitrogen is needed, no matter how much the plant screams for it. As a result, mother nature has given it the ability to consume the nitrogen stored in itself. Those big bottom leaves.

She'll keep sucking the nitrogen out the leaves till the end. That's when ACE comes into play. If the plant was in the ground. She'd clean the general area of nutrients. Not enough nitrogen in the area and it'll go yellow, Brown, gold.

No biggy. It's what they do.

I wouldnt look to expect that till it lays on some weight though. Honestly id feed it quarter strength. Ive seen plants go to shit in flower because ppl told me not to give more nitrogen. You certainly dont need to give much but id at least give it a little feed now. Its still in the stage where its growing vegitative matter it seems and hasnt totally transitioned into flower. You still want to give nitrogen at least through the preflowering stretch and i usually continue to give a small amount every third watering for a week or two after preflower.

I give the same levels of nitrogen throughout a plants entire life, i add more to the pk side at onset of flower, but i dont decrease the nitrogen

As for what would i do? Id feed it more, but wouldnt worry about a little yellowing just yet

Ive seen some people do that but then others claim this would decrease yield. i just hate seeing my plants dying in the end.

What do you yield under what size light if you dont mind my asking? Are your plants green at harvest time?

I yeild about an ounce per gallon of medium on average, plants are usually green till about the last few weeks then they fade just like everyone elses.

shes halfway through week 4 of flowering and day 67 from seed, breeders says 63 days from seed to harvest but its a very inconstant strain most of it being: genetic lottery x how well you cultivate it = what it turns out like.

This is a outdoor grow though so i guess they tend to bush out more meaning more time till harvest. I have not been giving her anything but flower booster for the last two.. do you think its worth giving her the nutes or do you think it will fuck up the final flush?

last two weeks*

i already voted to give some. your far from harvest there. i see at least 6 weeks ahead of you if not 8-10

forget what the breeder says.
