They def need a watering. I'm going out to game night with family so going to give them a plain RO drenching when I get home. No nutes or calmax if anyone has better idea let me know

I have noticed that now the lights have switched over my room has cooled. temps have dropped to 65f lights out to 68-70f when on. Is this warm enough? Right now lights on 69.4 just under canopy.

I just watered and checked my run off ph. So now to go along with my new temp issue I also am having a ph issue. Number one PHed around 5. Number two between 4 and 4.5. And number 3 around 5.5. Didn't make it to store for soil tester but will very soon.All tips for raising ph will be appreciated.

You definitely need to get those back into the 6+ range ASAP. When mine dropped that low on my last grow I flushed with 7 pH water until my runoff was back where it needed to be. After that things stabilized and I was able to keep things in check. You can also top dress the soil with some lime, but that takes longer to turn the pH around.
It was actually a soil tester that got me in trouble because it kept telling me my soil was 7 when it was actually 5 or lower. I only rely on runoff testing now.
You temps should be OK as long as you're keeping them in the 60s. I know that when I grew outdoor the plants seems to pack on the bud when the temps at night got cooler. But seedlings and younger plants like temps in the upper 70s.

You're saying to drown them with straight RO PHed at 7 about how many gallons should this take? For I only have the PH tester with the drops.
and should i do this tonight

2x-3x the volume of your pot should get you back in range... i'd flush to the ph range you want... then re-add nutes after the flush...

I started flushing my first lady put 10 gallons of water PHed at 7 thru her and the run off is still 5ish. had to stop and put her back cause lights out time start again tomorrow.
Unfortunately those drops only work with clear water...If the R/O water has any color to it at all, those drops are useless...If you ran 10 gallons of ph'ed water @ 7.0 through the pot, there should/will be a change in the R/O PH.
JM is right, the ideal PH for soil is 6.0 to 6.3 and the range for soil is 5.5 6.5
Get yourself a Hanna Pen PH meter. I have one and it's great. Had a Milwaukee meter, don't recommend that brand, they suck...

I don't have the flow for the hanna pen at the moment. just checked them and the curling is looking worse not better. Is this going to ruin my harvest? Is there anything else i could try. spent long time flushing the one with no result don't want to do that with other two.
