RQS Auto Diesel - Hydro

Been avoiding taking photos as i have ran into a little bit of an issue, but gotta take the good and the bad. All was going well, switched out the water/nutes and re-ph'd everything seemed fine. I saw a guide online that someone used aluminum tape, to "reflect" heat to keep their reservoirs cooler. I tried this, horrible, it jumped my res tank up like 5 degrees celcius, I have since taken the tape off and it looks like it might be bouncing back a little, roots are doing awesome though for what it's worth. Keeping a close eye on it and the PH levels. -Well had to go away over the weekend for a couple days, I think some nutrient burn or ph issues kicked in, although the PH was only 6.2 when I checked it... The temp seems to have normalized a bit. Did a little trimming of the crunchy leaves and added a bunch of plain Ph'd water which put the tank to 5.6 and I'll just have to keep an eye on the leaves. :( Sad thing to come home to. -Well, turns out my pH pen was WAY off on the readings, it was saying the pH was way higher than it was, so went back to the drops, looks to have bounced back a bit already! Here's hoping. -Final post for this week, here's what i've learned... pH pen from amazon, sucks - switched back to the drops, not an exact science using colors but it worked better than the pen already. After getting the pH back up to between 5.5-6ish the plant bounced back fast! have some fancy gold looking burn marks, but c'est la vie. This week I installed a carbon filter, have the fan inside the tent just above the grow light, and the hose running outside, the carbon filter isn't on yet as there's no smell anyways was mostly just using it for circulation at this point. I have the bottom vents all open so the air should circulate from the bottom up through to the top hitting the plant as it goes but also seems to be reducing the temp in the bucket. There was a clip-on fan sitting on the floor blowing air around as it came in through the vents, but I've since moved this up to the top, the plant seems to like it a little more direct on it. Next water change I will be trying the same nutrient levels as this last one less the voodoo juice, as well it's time to start training! it's up to 5 nodes already, super short plant so far.
