Hey, I've been growing some LSD-25 autoflowers, they're currently around day 33, been growing nicely in some bat mix by house and garden, but I've noticed the lower leaves browning and curling, and I cannot identify why for the life of me! It seems like it could be nutrient burn, so I flushed it with ph 6 filtered water yesterday, but I'm not sure what good it did, and I'm thinking now it could potentially be a potassium deficiency? we're using budget version airpots, and biobizz nutrients, although we halted use of them as soon as we saw signs of browning on the tips of the leaves. any help would be greatly appreciated!

Have you done a PPM check at all? I use a rule of thumb if your going to flush to a PPM check at the first signs of run off out of the bottom on the pots. Then do your flush. I do 3x my pot size ( 1 gallon pot = 3 gallon water/flushing solution ) then do a PPM test after the flush. Most times it’s about 200-400 PPM after the flush takes place. At this point your going to need to re feed as you just flushed all food from the median (soil). looking at the first pic I’d be rocking like 850 - 1100 PPM on the back 2. Just my opinions. Member it’s really helpful to write your data down. As you may take a clone and do another run of the same strain. Doing this allows you to “fine tune” or mess around and see what works better. Again opinions based of experience. Hope this helps. Long Hair CO

hey, sorry i don't currently have the tools to measure ppm, but we watered until generous runoff and the browning seems to have stopped for the most part, still not sure what it is that causes it.
