K here is a White Rhino.. Been starting to show brown spots on fan leaves. Mainly on the two larger ones on top and the first ones on the bottom. The bottoms are def worse and curling and twisting the most. The La Blanca I have is better but may start doin it soon. My PH is around 5.8, im using 1/8 nutes of what the company prescribed for veg growth. Here is my grow journal with all other info. http://forum.grasscity.com/indoor-g...th-cfl-white-rhino-white-widow-la-blanca.html
