PLEASE HELP!!!!! my clones are turning yellow, and the leaves curling up.... i cant figure out what happened! i took them last thursday, so its been a week, they all looked fine until i got home from work today... i cleaned out the cloner with ONA bleech and refilled it with plain tap water pH- 5.9. I dont understand~ some still look good, but some are starting to look f'ed... im trying to post pics now... some of the stems are starting to look brownish when i pull them out of the machine, like hay. HELP???????
