FastBuds GSC [Organic] (First Grow)

I tried bio ph down but it was a fail, those you named have weak acidity (you need lot of lemon juice to lower ph significantly) and are highly unstable just because the bio part breaks down and fade creating a slimy film of biomass. I found out that minerals ph down are way better, I’m now using sulfuric acid but you have plenty to choose from.

Hey dude - you’ve got nuttn to worry about here. These first couple leaves typically shrivel up and die off over time. It’s not likely to be a deficiency If you’re growing with a pre-loaded soil and only 2 weeks in. That said if you see the same symptoms persist on the newer growth over the next 2 weeks than yes - you likely have a calmag issue which u can treat as you like. I use a standard calmag supplement from botanicare (believe it satisfies the organic moniker for a liquid nute). I’d only start on an every other day feed regimen with calmag IF the problem persists. Good luck with ‘er, I’m sure she’ll turn out great👍
