Wrote down whats in this soil. Its actually B&Q soil (the potting mix was B&Q stuff so I thought Id be safe going there again)

It has - sphagnum peat, rich dark peat, fine bark, vermiculite (I also add my own perlite, about 20 percent), added plant nutrients and John Innes compost. It says NOT to use it with acid loving/lime hating plants. The pH of soil is supposed to be 6.3 with cannabis, so I know that its not exactly acid loving... although it can adapt to grow in many different places! Im just not sure how one strain - White Rhino - loves this soil, but the Lowryders dont like it. Ive been using the same germination technique since Ive started growing, and that was placing the seeds in some moist cotton wool in an old baccy tin on the shelf above my lamp where it stays nice and warm. Out of 12 or so seeds, only 1 has failed to germinate.

What the hell is up?

White Rhino is at day 10
Lowryder1 is at day 10
Lowryder2 is at day 6
Lowryder 3 is at day 5

Edit: WR is a little droopy because of an erratic watering schedule. Thats now fixed - I just got lazy
And yep, theres more than enough drainage holes. Between 4 and 6 depending on the size of the pots, and I also made them a little bigger with me dads drill
