Day 74 - still growing, but not looking as healthy as I'd like. Leaves are curling downwards at the tips, and tips turning yellow/brown. I think this is a one of the classic signs of overwatering and over feeding, so have cut back nutes and watering, and will re-assess next week whether or not to go back to old schedule. Have also diluted the reservoir, so oping that a slow gradual easing will sort things out. She also looks quite stunted in growth to me - she's all of 50cm tall. The RQS data sheet advises 80 - 120, but she has been in the RQS Royal Dwarfs shadow, so perhaps needed more of the light earlier on. I was warned about overuse of the PK nute and am think I've learnt my lesson here.
Fingers crossed all will be fine. On the up side, she's defintely flowering.
Day 75 - might be wishful thinking, but tip curling seems to have been brought under control and looks to be recovering. Phew.
Day 77 - definitely wishful thinking. Did some readings, and found ph has leapt up to 6.67, and ppm at around 2500. will ph down a little later, and continue to monitor.
