Banana blaze yellowing

[Awg52]

I was going away for a few days to watered Friday morning with half strength nutes. I came home last night and she’s yellowed badly on the lower half, with it looking like it’s rising through the plant. Some of the leaves have brown marks etc I’ll post some pics.

grow method: biobizz all mix potting soil (soils too hot I know, rookie mistake but I’ll rectify next time)

Feed: and supplements used: feeling around 2.5ltr water pH 6.5. Feed nutrients every 4th water at 1/2 strength of recommended biobizz grow, bloom and top max as per biobizz schedule.

water source: tap water with biobizz ph up to get 6.5 ph

PH in the root zone: not tested (note to self must test lol)

Strain/age: Banana blaze day 51 roughly

light used: Mars hydro ts600 , 24/7 and around 8” from plant (due to space, checked heat from light to plant and it’s okay)

Climate: averaging around 24/25 celcius as it stands humidity is usually average 57%

Feeding could be too low. Feeding only a 1/2 strength every 4th watering is much the same as constantly feeding 1/8th strength, which may not be enough.

Also, soil pH could be off; could be nutrient lockouts from excesses, being too hot; nitrogen deficiency or lockout looks to a problem; or could be the worst case - a combination of these problems.

Looks hungry to me.. Yellowing from the bottom up is most of the time a sign of Nitrogen deficiency
What's your feed EC or PPM?

Simillar issues here, my guess is calcium or nitrogen toxicity causing a potassium, magnesium etc. lockout. She does look hungry though. All you can do is test her and hope you end up with a harvest, my issue so bad atm 3 oz is looking like 1
