theGreek
started grow question 6y ago
Is it safe to lower the water PH with freshly squeezed lemon juice? Tap water is at 7.5, I am thinking of adding lemon juice to bring it down to 6. 5.

Very abnormal EC Runoff for CoCo Coir - please help on what I should do. I am scared to increase nutes in case I get nute burn
My EC going in is just under 2,000 (The maximum it should be much later in flower according to online) but comes out much lower and is getting lower each (735,467,368 respectively). Online says that Coco runoff will always be higher t- what should I do? I am scared to increase

TDS
I’m on week 6 today. Is this a good TDS reading or should it be higher/lower? I have the unit set to 500 ppm . I used 5 ml/gallon of tiger bloom, 2 ml/gallon of bud candy & big bud. I also added 1 tbsp of epsom salt to lower the ph in my soil.

Runoff pH still climbing!
My runoff PH keeps climbing despite lowering water pH. Plants look great but have red stems. Is it possible that the bottom of my fabric pots are saturated with excess Calcium and Diatomaceous Earth? Thus, raising my runoff PH. Soil meter reads 6.8 though 🤔

I’m out of BioHeaven
I’m out of Bio-Heaven and I wonder whether it’s worth getting some more, given that I’ll probably flush the plants within a few weeks and only use water then. Plus it’s quite expensive compared to BioGrow, BioBloom or TopMax… Any ideas or maybe an organic substitute? Thanks!

Accidentally poured 2mL of "Grow Big" into "Big Bloom" bottle.
I absentmindedly put 2mL of FF "grow big" directly into the bottle of"Big Bloom" (the murky one with bat guano). Is there going any type of reaction that will create products that would be unsafe for my plants? Haven't taken chemistry yet. Is it ruined?
