Thanks for the link. It looks like it is probably Calcium deficiency, but I have only noticed it on one plant out of 6. There is another one that has the twisted leaves and slow growth, but the rest are thriving, aside from the redness. I have also noticed the redness in the stems too.
dejayou30 Reviewed by dejayou30 on . Reddish Leaves? I have 6 Master Kush seedlings nearing the third week of growth. They are in an E&F system under four 150W CFLs. They are under 24 hr light and are being watered every 6 hours with 1/5 strength nutes. My pH is kept between 5.7 and 6.1 at all times, checked 3 times daily. I have noticed that the new growth has sort of a reddish hue when it starts and then turns gree as the leaves get bigger. I also notice it on the underside of some of the larger leaves. Is this normal? Anyone know what Rating: 5
