Im gonna have to say that I got better results with a 5.5 to 6.2 swing throughout the whole grow... Ill never go below 5.5 again that black and white chart fails to mention you will have a water uptake problem at low ph levels.
I can almost bet money that if you put a 5.0 next to a 5.6 or 5.7 the higher ph plants would look better if all conditions were the same. I just did it in my uc the last grow based off the black and white chart... they didn't look happy or feel happy till the ph was in the 5.5-6.2 range I even talked to Rob from HG about it that's how I learned about low ph having an effect on water uptake. Sure enough too when I ran it like normal they felt wet almost and were some happy campers. Idk if its just HG thats like that or what but my plants didn't like it at all. I been running the 5.5-6.2 swing with great results.I have seen 1-2 gallons transpired per plant site in 24 hours at 5.0 pH. Below 4.8 however i do see a drastic reduction.
With reference to PH, would you guys consider straight Sunshine #4 to be soil or soilless media? I've always mixed it 50/50 with either ffof or roots and adjusted ph to 6.3-6.5. This next run I'm planning on running it uncut. Should my PH target be in the hydro range (5.5-5.9) or soil range (6.3-6.5)?

Yeah that's pretty much what I thought too.I consider sunshine a soilless... I been having good results using a 5.8-6.0 on my waterings/feedings.
Interesting perspective but for my question isn't that just semantics? Do the ph charts consider products like ffof/roots organic "soil" and/or SS#4 soil or soilless?Soil is a combination of sand, silt and clay. None of the products at hydro stores are "soils".

What do you think of UCMENOW having a pH doser on every UC to keep pH very tightly controlled?
