The wr with the problem took on sativa dominant traits. 6ft tall. Others are fine and bushy about 36 in. FF nutes throughout cycles according to their grow chart(roughly). Started flushing last week with straight 6.8ppm ph water. Please help. Shes a beautiful girl, and She wants to finish strong. Problem leaves are from the middle up. Mainly on fan leaves.
I would say calmag, based on the ff line. They lack in calmag. I guess buy or borrow some calmag Next time add some Oystershell. Like 1/2 cup per bag.
botanicare makes a cal/mag supplement leafs that die off ass your getting closer to finishing usally turn yellow
wow, not sure what the issue is but your grow is very similiar to mine. Is this the grow you think you will get 5 oz's from? Just curious I am on my first grow so not that good at predicting what the dry weight will be. I have 3 plants. If you ever have the time pop over into my grow journal (in sig) and give me a guess on dry harvest. Lots of pics. Nice looking plant though
I'm also six weeks into flowering and using full FF line up, and had the exact same problem. It will get worse if you dont start using calmag. Use any brand, I have the botanicare. Like 13 bucks from my hydro store. Start to supp right away.
Thanks man. I started with molasses. Seems to have stopped the spread. To close to harvest to change anything major. Thanks for the help
