First time grower been coming on champion and the plant is 4 weeks old from sprouting today but my first 2 leaves fell off in the last week due to yellowing from the tip of leaves inwards towards him he stem, and the next 2 sets of fan leaves(4 altogether) have also gone yellow which I have pulled off, not overwater I'm sure I've let it go completely dry before re watering started using plant magic grow + at a third of what is advised, (1ml per litre), the pot I'm using is a standard builders bucket with drilled drain holes( plenty of ) if you'd could point me in the right direction of keeping the plant healthy I would Be chuffed
Thanks
