HELP! HELP! my Auto-fllower Quick one from royal seeds is getting brown spots!

[GrowCanabis198]

Hi everyone,

I am growing 3 plants (quick one from royal queens) indoors and unfortunately I have been facing few problems, I am assuming that my first plant has a potassium deficiency, which I am not sure if it has stopped or not (Its the plant that looks really pale/yellow). my 2nd plant is really dark green and today I have noticed a spot on it, which I have no idea what it exactly is. Please help! and advice me for the future and now

I am growing using:

200w light. Height: 40-50cm
temp: 23-29 degrees
water PH: 6 to 7
Fertilisers: biobizz, grow, bloom and fish mix (I only started using it 2 feedings ago)
light schedule during flowering: 18-6
light schedule in the beginning: 20-4
soil: https://www.bauhaus.info/tomatenerde...ker/p/27215593

Thank you so much!

First of all. in that soil do you have perlite or leca in it for drainage and for oxygen ?
what are your PH levels? In soil ?
For me; some of the plants look like they are drowning ??
the pale one; it’s made some tacos, for from I can see, and I think the pale is missing nitrogen actually

nute burn imo

either potup to the next size pot include 30% perlite

or extract soak roots in air temp water then replant in clean mix include perlite 30%

most growers go 2-3 weeks before feeding (read the label)

good luck
