Fast buds Forbidden Runtz

Well we're in flower!!!! Look to be roughly a week in maybe more. Looks like the one that's a bit further along possibly has a bit of heat stress going on. Not surprising seeing as we have had crazy heat the last few weeks. Up to two days ago been struggling to keep the tents below 30c. The only other thing it could be is that my Ph has been off. Last week I noticed it had jumped up to 7.2 over night for absolutely no reason, had it rite at 6 like always. Then i noticed that it had jumped up again a bit. Today i went and looked and it had dropped all the way down to 5.5...... wtf. So i decided to test my Ph pen to see how accurate it actually is. My other tank has a full monitor system in it so I put the pen in the water there and noticed that my pen was reading almost .5 lower then my monitor. Cleaned it off and tried again and it was now reading .3 above my monitor now.... so clearly my Ph pen is hooped.... yay lol. With all the issues ive had this far im curious at how well this grow well end up being and itll be interesting to see how long it takes them to finish up. I'm guess about 6 more weeks, but we'll see. Happy growing everyone!!!
