Several issues

I have a Green Crack and Bloody Skunk autos that both took a turn for the worse a couple of weeks ago. They are currently about 9 weeks in, and for the last two weeks the leaves have been yellowing, and more recently getting burned spots, along with bud growth being almost non existent since the yellowing started.

First I suspected I had the light too strong/close since the leaves around the periphery are doing much better, but even after raising the lights and lowering the power, the plants continued to deteriorate. I'll list the problems in the order they appeared. PH of runoff is around 6.2.

  • Leaves started yellowing, especially in the center of the lighting.
  • Leaves started curling, not from the tips inwards, but from the edges inwards.
  • Some burn spots started to appear.
I have them in 2/3 fox farms soil and 1/3 normal ace hardware potting soil. Gave them some nutes (possible a bit much the first couple times due to some questionable conversion to metric), which I know Autos can be sensitive to, but I've had pretty good success on previous ones. Minor LST (just main stem). Once the issues started I eliminated the nutes.



The attached pics are where they are at now. Buds look good, if small since they have been stunted since issues began, and pistils are starting to turn orange. I'm hoping I can correct the issue and have them put on just a touch more weight in the next couple weeks before I chop (assuming they don't keep deteriorating and I have to chop early).

Looks a little defficient and or maybe overwatered. How are your room temperatures? Heavy purples could also mean youre too cold and locking the plant out of nutrient uptake.
