Should I use PH Down?
bonifacil420started grow question 3 years ago
Today I measured the water ph before putting any nutrients and it turns out it was 7-7.5 ph but then i measured the water that came out of the bottom of my pot after watering (i put some biobizz nutrients) and it was 6.5ph should I use a ph down? I have 1 so im not buying. TY

Nutes tend to bring down your pH. There are a few exceptions like silica, but the big 3 pretty much always bring your pH down (unless your water is already acidic as in the case of acid rain collection).
You can be pretty confident that your pH was good after you added nutes and if your runoff is at 6.5, then don't change a thing. Keep growing!

Soil is a natural ph buffer, i suggest u only bio ph- unless they are full of chemical salts and u are better with straight tap water

You ph test after adding nutrients. I use GHE and my ph is always bang on. So if you didn't check ph after adding the nutrients the feeding could have been in the correct range.

WateringPlants seem to respond oddly to watering…. It’s like they look like they want water, but then when they get it, they act like they don’t want it… super weird. Maybe since I’m new I don’t have the knack for knowing how much to give them ¯_(ツ)_/¯Week 3

Help me avoid over/underwatering my girls..Almost done with 1st week, watering my girls 50-60ml each, once a day in 2L pots.
It's 28C (80F), humidity around 65.
I check the soil (1inch deep) but still feels a little wet even after one day.(despite little water and 80F)
Should I still water them as they are still seedling?Week 1

Ph drop after res changePh dropped hard 24 hr after res change @ 60%. Had changed 1 week prior due to high ec + slowly dropping ph and added another air stone. Turned off the air stone for an hour, no change so likely not acid rain situation. Ph up’d, plant never showed signs of being unhappy. Thoughts?

Calendário PlagronOlá, seu eu seguir este calendário, vou obter uns bons resultados ?
As minhas últimas colheitas foram as primeiras, não estou triste, as flores saíram lindas e saborosas.
Mas os buds não eras duros e densos, usei fertilizantes biobizz.
Mas nenhum supemento NPK, foi o que faltou?
