I wrote that in a hurry, so sorry
@Vapo69 @Mañ'O'Green that's my fault for not clarifying what I meant by "plain water". I just meant without the nutes. The water was PHd, with Cal-Mag and Great White. I admit that this is clearly not plain water and that could obviously cause confusion for others. When growing in coco, that still feels like "plain water"!
I feed/water when they feel like they need it basically. Generally every morning before heading off to work but there are some days they need to be left a little longer. I judge that by the weight of the pots and whether they feel damp or not. They're never left to go completely dry though really. The coco/perlite mix provides a lot of drainage and I'd be surprised if I was overwatering them, it would be the first time I'd done that but these plants are smaller than I'm accustomed to so who knows, it's entirely possible.
I'll upload some pics when I can. Still no sign of the 5000k I ordered though.
I don't have a PH probe and I'd love to get one but with various other expenses this month and Christmas around the corner, I can't see myself making many additions during this grow. I'm debating packing it all up after these have done their thing and waiting until I can afford some cobs before starting any more plants. The cost of running the HPS is eye-watering and unless I'm pulling fairly big yields, which I'm not expecting from these plants, I'm not sure it's worth it
Thanks for recommending that guide
@Mañ'O'Green very useful.
