Kush Cake (sensi seeds)

Started off in 15 L Aquapot with added airstone in the bottom, layer of clay balls n a rough mix of bio bizz soil(black bag). Also some Ecothrive Charge also the liquid seaweed extract, after a week or so as was very beneficial for using it 1st time on last grow. Have ViparSpectra XS1500 pro, which is perfect for my 2x2 but also have a P600 for additional lighting during flower i was thinking of using as supplementary light during late flower (if anyone can give me any info on that as the XS1500 does fill out aalll the way to each corner of the tent and 800 par even around the very edges. Last plant of Purple Domina ended up with what I thought was root rot as I used an aitpot in the Aquapot system but fed from the top. Anyways, weekly updates on this, good bad n ugly. Pls check out my YouTube channel as iv barely 10 subs!
