inreplyavalon....I use the pre charged 50L purple sacks of Bcuzz coco.
go to the basics and water twice a day at least and, yes, be consistent.
start small containers, size pots and transplant accordingly
After reading this thread I decided to check my PH on my runoff. My plants look pretty darn good but some of the larger older leaves are a bit off(yellowing spots, brittle, etc.)
So I water with RO @ 5.8 PH (PBP, calmag, lk) and I check the readout of the runoff yesterday and it 4.0-4.6 on my meter and confirmed with PH drops. I have started flushing with 6.0 PH plain water. It's taking about 10 gallons to get the runoff to ~6.0 PH in 3 gal bags.
I think I've built up a ton of salts from previous feedings. I have recycled this coco a couple times, and stupidly not flushed it thoroughly before using again. They actually look pretty good considering how acidic things were. Some of them don't really have any noticeable damage, but I don't see how at that low of PH. Growth hasn't even been to slow.
So did I do the right thing by flushing out all the salt buildup? I just don't see what else I could do to change the situation.
Sorry if this would be considered a thread jack, but this is the thread that made me check my run-off PH. So I have Seed Buyer to thank for getting my head out of the sand, or should I say coco.
