Hi, my husband and I have started our first grow. We have seedlings that are a little less than a week old right now. They are in Fox Farm Light Warrior. My question is what should we ph the water to when we water them?

If you're growing in soil, and your water's ph is between 6.5 and 7.5 i wouldn't bother changing it at all.

Ok. That's what we were thinking. I've read some posts saying to treat light warrior the same as soil and I've also seen it referred to as soilless and to treat it the same as hydro. We were leaning towards treating it as soil though. Very much appreciate your quick response, thank you

Good advice even up to 8 phIf you're growing in soil, and your water's ph is between 6.5 and 7.5 i wouldn't bother changing it at all.

Thank you. We've been lurking for several months now trying to research and learn as much as we could. I think we've prepared ourselves relatively well. But I'm realistic, this is our first go at it so I know we'll have questions along the way. We always try to find the answers ourself first, but it's a relief to know there's a community of people with experience that are willing to help.

Keep ph at 6.5 .... FF soils fall in at 6.3.

Ok, we've been using distilled water that is ph 6.5, so we can keep using it and not adjust the ph

Like others have stated, most tap water is fine for soil right out of the faucet. People don't pH when they water houseplants growing in soil. They just fill a container from the sink. Cannabis isn't special. It's just another plant. Treat it like one and they will grow just fine. It's when people over complicate things where they start having issues.

Thank you for the reminder that in the end it is a plant. This is something we keep having to tell ourselves. We want to give them the best possible chance to grow to potential so we're trying to learn everything we can but I know that's causing us to over think some things too. With it being our first try were just trying to be careful and not mess it all up

How about soilless?In soil its not the ph of the water but the quality. If you wqnt exact answers on your water you need to post up your water companies detailed analysis from their website.
We all done it at some point - ph is meaningless in soil, it does not tell the wider picture

Are soil and soiless the same thing - media with high cation exchage and probably limed.
Some do hydro and coco at what is considered bad ph and do pretty darn well.
Its a hard subject at higher levels so i couldnt really say the exactings of such things

6.0-6.8 ph for soil. Nutrient lockouts can occur when exceeding these ph ranges. If you've been testing to 6.5 you're in the money. Good luck on your first grow, its an amazing process.

These well meaning folks are giving you a number but they aren't explaining anything, which does not increase your understanding.
First, pH is not a measurement of the water itself, but rather the total acidity of the materials suspended in the water. Put another way, that means that pure distilled water has no pH because there isn't anything dissolved in it to give it one.
It's also helpful to understand that the more minerals in the water, the stronger that relative acidity will be. If there isn't much of anything in the water, whatever it reads is irrelevant.
If you're watering your plants in soil with distilled or reverse osmosis water (a form of purification) then don't waste your time trying to figure out pH. After all, who treats their pH when they water their lawn?

Those ionic elements of the fertilizer will conduct futher chemistry upon entering the soil, its not like they are in solution merely balancing the formation of certain elements at certain ranges like in hydro.
Imagine a hydro res, now drop a load of soil in - does the ph stay stable, no chance soil acts like a res and hence we can only guestimate ph and such - some farmers vary their nitrogen nitrate ammonium ratios, others lime and such some do all some level it to nature needing to fallow once in a while.
If your intention is to grow in soil you need to learn soil and not hydro stuff imo
