I did a flush about a month ago, but probably got over zelous as I used about 15 Liters to try and flush it good, but probably caused over-watering issues.
The plant is all nice and green, yet about 5% of the leaves have yellow rust like spots, and drying tips that crumble. Even some of the canopy leaves are getting kind of winkled and about 75% of all leaves have curled their tips recently. Its been about 4 days since she got fed and it might just be signs of thirst or that its killing off leaves since its almost done flowering.
About 15% of Pistils/hairs are red, and this one got potted with some MG premium potting soil (back to sunshine mix). Now my waters PH is 7.4-8 but I for the first time checked the water with nutes and the PH is 6.6.
I did a cheap run off test, where I poured straight 7.7PH water along the side of the pot and collected 7.7-7.8 PH run-off. Now I don't know if I should do a better test, or try to bring the PH down. I've managed to get away without bothering with PH so far and I plan on going to DCW after my next 3 are done in 7 weeks.
From what I've read it could either be a Potasium (K) deficientcy, Slight over watering, or from cold roots. The soil is around 50 degrees F, and I tried using the ballast to heat it up a bit, but its too scary. I have them off the ground in a garage, but its been pretty cold lately.
I'd post a pic, but my camera doesnt do Macro, and I have a bad experiance with taking pics of plants. Bad Mojo for me. Now I'm not panicing, but I'm watching it closely and if I see it start to burn up or wilt big time I'm chopping the buds before they go bad.
I'm giving them "Dr Hornby Big Bud", Carbo-blast, Super-B, and 7ml/1L part 3, and 3ml/L part 2. I haven't had any issues at all besides this, and my temps are 60-70 F and lots of ventalation. maybe a bit low on humidity but I mist them twice a day.
I've also noticed the leaves are kinda dry and easily broken compared to the younger plants, more so on the huge sun-leaves. I've seen some small yellow spots on the leaves, but it maybe from water drops, although I suspect something else.
It sucks if its K deficientcy, since I don't know if I should bother trying to fix it, or just flush the plant. It has to be fed soon either way, and I'm still on the fence if I should give it, its normal food.
