Auto daiquiri lime indoor

[Espeon]

Hi everyone, I am a novice grower and after having reread myriads of advanced processes and techniques, I am completing my third cycle!
I state that I have basic materials and have spent little (of course it will affect the quantity and quality of the relationship)

I have a 60x 120cm grow box

Soil: cellmax Bio Soil Mix
Lamp: CFL greenpower 250w
Basic ventilation and aspiration system
Seeds: autoflowering Daiquiri lime
Plants: ne (perhaps too many given the space and no sog or sgrog system adopted)
Light cycle: 18/6
With light on humidity 60- temperature 28º
With the light off humidity 50- temperature 24º
Soil pH 6.5

I'm on day 40 and the flowering process has started a few days ago
unfortunately for some days the leaves have started to become dry and burnt as if I had given too much nitrogen!
as fertilizer I have always used only the b-52

waiting for advice, thank you in advance

Looks like a potassium deficiency but.........................

Please fill in this form: (copy and paste part is below, this first one tell what specifically to include)

-Problem: (brief description)
-Medium/grow method: soil; soilless-- coco, or peat based like Promix, etc. (please provide the actual product name); DWC, NFT, etc.
-Feed and supplements used: include brand, dosage/strength, frequency of feeding and watering (alone); method-- by hand, drippers, rercirc' or drain-to-waste,... N-P-K #'s too if you can!
-Water source: RO/DI; tap- dechlorinated-?..... EC or TDS reading; pH (don't bother with this on RO/DI, do bother with TDS/EC though to confirm it's working well enough)
-Strain and age
-Climate: night and day ambient T and RH%; res' temperatures; any extremes in T/RH% exposure
- Light used: HID, LED, COB, combo of,... wattage; light cycle hours (20/4, 18/6 , etc.); distance to tops....
-Additional info: PH in the root zone. How long have the plants been affected?...How fast did symptoms appear?... Anything else you think might be relevant..

--Pictures including WHOLE PLANT PICS, and troubled leaves.. use normal light or flash as other light sources ruin color rendering, critical for diagnostics!

cellmax Bio Soil Mix
NPK 10-2-5

I only used B-52 (NPK 2-1-4)
throughout the vegetative phase
plus 2 times ox blood
finally I added coffee grinder (perhaps ruining everything being rich in nitrogen)

water source:

cooled tap water, idk ph

Strain/age: 45 day

light used:
8U-CFL GREENPOWER 250w 2700-6400k

Climate:

light on temperature 28º degrees humidity 55

light off temperature 24 humidity 40

vegetative cycle 12/12
flowering cycle 18/6

I wanted to start giving PK and adding potassium through an infusion made with banana peels

I flushed to remove everything they had in excess!
now I start to give potassium with an infusion of banana peel and Pk ...

Interesting soil.....I might have to try some..... Quite frankly I would never have fed the plants anything..... I would have ran this soil and focused on building a diverse population of Bacteria and Fungi, and allowed them to care for the plants needs, while having a watchful eye and waiting for the plant to tell me what she might be lacking and not getting from the biology in the soil..... I know there are many ways, I just do it a little different then most.... I rely on nature and simplicity...... anyways good luck with this grow, it is always a fun learning adventure with many twists and turns...

60 day
I am using the pk to help the flowering and I immediately noticed some improvements in the compactness of the buds
