Hey everyone,
So I'm doing my first ever grow in coco using dry amendments. Coco was washed and buffered properly, loaded with worm castings /mycorrhizae/ dry organics. Had absolutely stunning growth during veg with tap water pH'd to 6-6.5. I did two toppings in two weeks and it grew so fast I flipped on week 4 of veg to keep it in my tent boundary. Before flipping I transplanted to a new pot with fresh mix, and here is my guess at mistake 1: All of the fresh mix was concentrated towards the very bottom of the pot, and often did not get wet enough. I think I was overwatering in terms of frequency but not quantity, meaning I was only watering the top half of the coco and roots never grew into the new mix. I've fixed this by bottom feeding the pot and running a light flush every 3 days.
Issue 2: pH fluctuations in time
So things were going great, 2 weeks into flower I set up an auto watering system and leave for a week to take a trip. I come back and the plant has done this:
I didn't know it yet because I didn't test it right away, but the water in the res had drifted up to 7.5 pH. I later ran an experiment and found that my tap water drifts all the way from pH 7.x to 8.5 if left to sit out, not sure why this happens but it does
Like a dumbass take the first advice I got, which was calmag. I did 1 watering at 5 mL/gal, and I believe that caused this burning:
The clear light pics are from Jul 18 and the blurple from today (7/25). From what I can tell my improved watering routine with corrected pH (I leave another bucket of water out overnight and pH from 8.5 to 6 then water with that) have slowed the bleeding but not stopped it. The pistils are starting to turn orange but the buds are very weak so I'm wondering if I can or should even try to save this or just save the 2-3 weeks and replant? It's gotten super frosty but the density just isn't there yet
