I was under the impression when using super soil ph didnt matter

I got it to 5.9 and said good good enough. How can i tell if its helping? And that seems like a low ph?

I need help. I dont know what this is. It happened my last grow too. I run city tap water its 250ppm at 6.8ph. I think my water may be the cause. I am running roots organic soil with a super soil blend of organic nutes. Im probably 2 weeks into flower. It's sour kush from sannies seeds.

I flushed with 6.4ph water and checked the soil runoff it was 6.6ph. So I know it's not nutrient lock out. Should I just dose the crap out it with cal mag.

I switched nutrients from general organics to dyna gro. I think the g.o. may be old.

What where your poor watering habits?

I am pretty sure it's mag def but I want some other opinions. The biggest plant is showing red and purple stems really bad and this leave below. The other 2 aren't as big and the stems aren't as red but they have the discolartion and rust spots also. Ive been giving them tap water at 210ppm with...

Inside my box is running around 82 with 40-45% rh. My room stays around 70 and 65-70% rh. I think i need more intake and to refill my filter with better carbon.

Im in week 7 of flower. Im almost done with this crop. Its the future crops im worried about. I wont continue unless i can get 100% smell proof. Also after putting my hygrometer inside the cab its only 40% rh. After this grow im going to replace the exhaust and see if it fixes completely.

Alright guy's im still getting some smell occasionally. I think my carbon filter maybe getting too much rh. My rooms average is about 70%.

I checked the exhaust hose and sure enough lit up like new years. I duct taped it up real good. No more light. Now lets see how it helps. It was stored wrapped up in thick plastic. I dont think its my filter. Once i wrapped the exhaust i didnt detect any more odor in it. Thank you all for the...

Its pulling through the filter exiting out the back of my cab. I notice when i close my bedroom door it seems to smell up the bedroom. I'll look at the exhaust tonight when lights come on. I was thinking i might not have enough negative pressure because if it was a leak it would smell all the...

No i dont. I re did the connection between the filter and fan gonna see if thats it. It dosent stink all the time thats what is getting me so frustrated.
