ROCKWELL NEED HELP CANT TELL IF MY PLANT IS OVERWATERED OR UNDERWATERED

I'm growing indoors in rockwool cubes 6inch stacked on another 6 inch cube, top feeding on a drip i have been hand watering at the start and I'm day 22 with one chocolate mint go by humbolt and been water like ever 2 day or so when my cubes almost dry but the bottom one always stays wet and seems to get all the water but i thought i might switch it top feeding as i saw on youtube you supposed to feed 2x in veg at like 102ml +102ml because i have 2 cubes but my plant has been looking very droopy can anyone help me with any advice first time in rock wool and my plant seems a bit behind



sorry I've I've posted this the wronge place I'm kinda new here any advice will be helpful thank you

You don't start on cubes that big. That's why there's so many sizes.

yeah they were the only big ones they had in my hydro shop near me what should i do ?

you're fine, your plant is doing ok. just keep that green cover on top of the block

okay thanks so much for taking to time to reply i thought they'll be fine but how will i get the fan leaves to perk up or will they stay the same ? and when should i switch to auto feeding them ?

your plant looks completely fine, if you want it to to perk up, you need to get it all dialed in:

humidity
light levels
temperature
nutrients

yeah i thought so my
humidity 50%
light like 80cm had to adjust because leaves started to curl bit
temp is 25 C
and I'm using canna vega atm

Is that lights on or off?
I think you have them stacked too high if the bottom one always stays wet.

I didn't know you could make a title that long...

I don't know how big those are supposed to get or where the roots are going to go in the future. They should grow though if you get the watering schedule down and don't over water (and overfeed). I used to put 6" rockwool cubes on top of rockwool slabs and grew 5 foot plants with drip irrigation.
