Leaves starting to yellow from base up

[Lineker89]

Hi all,

Been a while since i post in here. Posting for a friend this time, his baby has his leaves yellowing from the base up and I'm not entirely sure what the issue is.

Sugar Mango grown in BioBizz LightMix, 10L pot, roughly 8-9 hours direct sunlight in Mediterranean climate. Biobizz fishmix only nute used so far, 24 days old.

As you can probably guess from the picture, it stretched like a mutha fucka due to the light restrictions on his balcony (stealth balcony grow). Im thinking that the light intake may be the culprit, i doubt it is from a nitrogen deficiency as he has fed it with biobizz fishmix @ 1ml/L twice so far, switching to fishmix + bloom next feed.

Could it be nute lockout? 2 feeds only so far but no clear water in between, if so is a flush in order? Im worried that if its a deficiency then flushing will worsen things.

Or is it due to less light and stretching?

Will upload closer pics later.

My mans mans attached to his baby and we need to get things right, thanks all for the help.

Peace

She looks like she's starving mate. Biobizz is pretty mild and 1ml/ltr is not enough for her. When I was using biobizz I would also mix it with every watering, try upping the fish mix to 4ml/ltr for a couple of feeds and see how she responds.

Hi man cheers,

Weird though because my girl is 21 days today and so far only watered / fed once since broke soil (presoaked before planting direct to ground), 4L with 4ml fishmix as with autos you dont want to start strong. (Check photo below)

Saying that though my friend has been following a different watering schedule, his first auto so maybe that's a reason.

My 3rd grow using only biobizz, never had a nute def issue with mine so I'll get him to up the ante to 2 fishmix and 2 bloom on next feed as already showing signs of flowering on his. That sound right?

Cheers for the input, AFN guys never let me down

While it's completely natural for a plant to drop its first sets of leaves as the top matures, that plant looks a bit too young & small to be experiencing that. I do believe you're seeing a nitrogen deficiency because organic grows are a different animal. ANYTIME you start a new grow with new dirt, and you're growing organic only (fish shit, worm poop, bat do-do, etc.) you have to start your soil at least two months prior to placing your plant in the bucket. Even longer is better. In my younger days of outdoor grows, I would start my amended grow holes at the end of the summer and let them percolate until late spring for planting. You have to start applying the teas that feed and jump-start your beneficials, and give that whole ecosystem time to establish itself. Otherwise all the "things" that make organic work are not there to do their job.
If your friend is more interested in having a healthy plant than he is in staying purely organic, a little jump start with mineral based nutes will alleviate this problem almost immediately. If he's not willing, nothing to do but frown and bear it. You can try up-ing the nute strength but once again, in an organic environment it takes weeks for this to take hold in new dirt.
If this were a photoperiod grow, he could ride it out by keeping the plant in vegetative growth until it took off. But that "wait and see" approach with autoflowers is much tougher on the plant once it starts flowering. It will still grow, but the plant infrastructure (roots, main trunk, branching) will not develop enough to support a large yielding plant.

Here's the effects - the following is a Dutch Passion Mazar, transplanted one month ago today. Granted, I grew it to four nodes under a CFL before transplanting, but everything you see in this pic has grown since transplanted using mineral based nutrients (GenHydro expert recirculating) with plenty of plant and mineral based additives.

Your call. If you don't want minerals in your dirt, at least add molasses every third watering. Nothing jump starts the dirt faster.

Thanks mate, using a biobizz lightmix substrate with added perlite so soil was good to go, living on an island in the med with no growshops makes access all the organic components a bit tricky.

He fed 2ml fish and 2ml bloom per L @ 4L last night, lookin much healthier this mornin.

Are the leaves that turned yellow going to return to green or are they going to stay yellow?

Peace

- good advise from all but the one, now banned- .... Joe, get your friend to use the full line or another base nute, I don't think that fishgoo is a complete feed, secondary and micronutes especially,.. most of these products are meant to be used in conjunction with others, which cover the full nute profile,... low level defc.'s may not show outright, right away, but can hamper the uptake and utilization of other nutes, making it harder to pick apart for causes,... micro's are particularly notorious for this, like a small missing "part" that jam's up the rest of the machine!

looking alot better today thank you all for your replies
