answered grow question 5y ago
No. You need to drop it to between 6.0-6.5 for soil. Or 5.5-6.0 for Coco or hydro. A pH down solution will be required or you will have lockout issues. Happy Growing! 🤟😜

Questions about watering
I created a 40 ml solution, the instructions say to transplant after the sprout has grown to the top of the plastic cover and the roots are visible through the plug. The question is, is 40 ml of liquid enough for this growth? I think not.

Wilted leaves during mid to late bloom.
Hi, I skipped watering yesterday and the leaves were wilted this morning, gave 4,100cc nutrient water this morning. My question is how much will this set the plant back and can I expect to salvage the crop? Thnx.

Dumb record keeping question: I don't add more nutes every week, so should I leave the same mL/gal entries as the previous week, or enter zeros? Thanks for reading

Calcium in tap water
Is 95mg/L calcium too much in tap water? (It's probably a little lower than that, since that's exit measurement from the waterworks.) I haven't seen any signs of acute calcium toxicity, but I'm worried about buildup.

Nutrient Deficiency
I could be wrong, but it looks like my leaves are starting to show signs of deficiency or am I just being paranoid?

Did I give too much fertilizer??
So I decided to add in some soluble fertilizers. I gave it a 1/4 tsp (50% of recommended dosage) a couple days ago and noticed some yellowing of new growth on the bud sites. Is this a sign of excess potassium and phosphorus? I gave it Fox Farm Open Sesame (5-45-19).

Outdoor Hempy Bucket fertilizer use?
Added perlite and clay mix to a 10L outdoor hempy bucket, with Skunky Lady on top. Curious about hydroponics fertilizer use outdoors, should it be added early or wait for some growth when the roots hit the reservoir? Seems like it would be wasted if I add it early on....

PH falling caused by dilution /hydro
I noticed that when I dilute my soup too much with osmosis water in order to lower EC, PH starts falling eventually, even when my soup is a few days old (I have an air pump, it always goes up). Does it mean I have to make a new tank in that case ? why is that happening? Thanks!
