Very true mate. I've done 2 plants in 1 Res twice now with autos. That's always a daft idea for way too many reasons to list. And 4 days ago I just put 4 photos grown from seed into a 20L NFT reservoir. They were a fair size when I put them in too. Vegged em for a month in the cubes so this is probably gonna end in drama and bloodshed but im doing it anyway cos im in a hurry and it seemed a good idea untill about 3 and a half minuits ago lol. Shit haha should've used clones. Ahh well.. it'll be funThat's the challenge with a group rezz
No plants, even same Strains, act the same
I use separate, individual, 5gal DWC buckets. Easy to change each if needed
Like I said, my Purple kush was a nightmare
I'd drop the nutes like I said, raise that light to 24"
And DWC pH is best at 5.6-5.9
