PH below 6 bad for plants potted in soil?
Filiaesstarted grow question 2y ago
The Hesi nutrient scheme is reducing the ph lvl of my water below 6 and am asking myself if it is really good to have such low PH for plants potted in soil. Be ware that I use Osmosis water and mix it with a bit tap water and canna calmag to adjust the water before adding Hesi.

It's a little low for flower, if you were in veg I'd say don't sweat it as veg cycle does better a little acidic. Are you running an airstone in your reservoir? Depending on how long it sits it may be beneficial plus it will likely raise your pH a little bit too.

You defiantly want to bring that up to above 6. I’m not familiar with those nutrients and their instructions but I know that the majority of nutrient manufactures tell you to pH adjust AFTER you mix everything together.
I use RO water as well and my pH is very high, in the 8’s. When I mix my nutrients it comes down to the high 5’s. After everything has been throughly mixed, I adjust the ph to 6.3-6.4.
Any pH up product will work for doing this just be careful as a little goes a long way.
I hope this helps.

mineral wool "turns green"Over time, the top layer of mineral wool "turns green". The problem is probably that the humidifier is located too close to the plant.
I don't know.... to close the substrate from entering the light ?!

Is My Critical AUTO a Photoperiod Strain?I have 3 auto strains, 2x Thunderfuck and 1x Critical. The Thunderfuck plants bloomed normally and have been harvested. The Critical, except for a few light pre-flowers on one stem, hasn't bloomed. I suspect it might be a photoperiod. Should I put it in the tent at 12/12 or 18/6?Week 14
