Issue with yellowing during final stage

[Medimadness]

Hi there AFN haven’t posted a plant in here as i rely on my journal responses and intuition for the most part but i’m a little stumped here.

Basically i have a critical Cheese auto by zamnesia seeds here (called Greta lol).
Anyway Greta had a bit of tip burn but not much really, so as a result i pulled back on the concentration of my feed (Biobizz line-up, soil included. Currently giving her 0.75ml/l bloom 0.75/l Topmax and Calmag at around 1ml/l, using lemon juice to take my nute pH down to 6.5-6.7 since i have pretty high pH water after standing here) and i feed her around 1l every day depending.

Anyway now the tip burn has sort of died off with the dead material curling upwards, however I am seeing some yellowing of then upper foliage by the buds that can’t be caused by my LED reflector (300w marshydro at 13inch distance) and am now thinking she is actually hungry but obviously i’m a bit scared of overfeeding now.

If anyone has any insight despite the poor picture quality i would be very grateful.

Cheers

Feeding seems quite low to me....I would be upping the bloom at least. Biobizz is fairly forgiving and seems slow acting I wouldn't think doubling the amount of bloom your giving would do much harm this heavy in flower.

Looks more like a lock out, Have you checked your in pot pH lately? How old is this again?

59 days old, pH locking out nutes with my biobizz light mix/ and feeding them around 6.5 isn’t going to be causing any harm. The soil buffer takes care of most of that.
The organic nature of my lineup takes care of that for me anyway

I agree man, i ended up giving her another .5l with 0.75ml/l extra bloom in there after checking their feeding schedule and then correlating that to an autoflower timeline.
Seems 1.5-2ml is more what she’s needing at this time but i’ll see how she does.
Since i’m seeing P-K deficiency but also N burning that must have just been from the overfeeding before it’s obvious i just got a little too timid and my anxiety over powered my mind lol tbf.
I’m sure she’ll be fine soon.

Cheers for the input though man, it’s good to have a little reassurance

Ill keep this up just in case her condition worsens or otherwise

Okay then, good luck with that!
