If it was just the purple stems I would not say anything. But there are 4 different signs. Purple fans stems, Candy Caned Fan Leafs, DARK Fan Leafs, and Ram Horned Bud Site Leafs. I have a few crops under my belt, but have never had all these things happen at once. And I do not want it to get out of control. This is a nice crop right now. But i know how things can get out of control if let unchecked. This all started since I entered flowering stage.
The dark leafs might be over nuts, but I was only at 1200PPM total in second week, and only 850 in the first week, so this I highly doubt. Maybe this is nothing. I have changed over to Advanced Nutrients two Part A/B. So maybe this is just the way the plants look with this type of NUTS. Time will tell. Tonight I did drop back to watering only 3 times a day, (Hydro) Maybe more oxygen to the roots will help. I did Add BIG BUD to the soup tonight also. 0-10-40 This should raise the Phosphorus. And then next weekend I will pump out the 40 gallon res. and do a good flush with straight PH'd water 3 times a day for 2-3 days, and then start with fresh soup. Maybe I am getting a little Lock-up. All in All, They are budding really nice, and the trichs are already forming nicely also, So I do not want to do anything to extreme as of yet. My first harvest I had a bad Calcium deficiency, and i got a nice harvest out of that one.
I would be so much better off, If i took as good of care of myself, as I do my plants.
