1st Grow: indoor photo RQS

Second Day Week 5 of Flower: Day 71 So i hope i reached rock bottom and it goes up from here. The ladies look like they've been slaughtered. But i flushed them two days ago with 5l of pure ph'ed water. Because my PH Meter broke on that day i wasn't able to give them nutes in a controlled fashion. New PH Meter is on the way and should be here in a day or two. So biggest question now is: Do i eyeball the ph down for this feeding, which i am quite hesitant to do honestly or do i wait for the ph meter and feed them then? Well damage is done, the fuck up has happened so i guess i wait for the ph meter. Maybe its worse, but at least i'll know i get the meters correct. They still are moist enough so i guess they have to suffer a bit more for a day or two. Sorry ladies! I try my best! Found a workaround for my dilemma: I could get some ph teststrips (for aquariums) and fed the ladies with 1l of nutewater each. Lets see what happens. So Day 71 is the first feeding day of this week. Day 72: After overcoming the shock involved with seeing the girls look so fucked up its time for some notes for my next grow (of course i try to ride this rocky road till the end): - Biobizz says, usually you don't have to adjust the ph when using their fertilizer and i think they are right. Things started to go downhill FAST when i started to give a third of the feeding with plain water. I thought it'd do them good because i diagnosed some burned tips (and i thought it was nute burn). So because my tapwater has a PH in the 8-8.5 range and the nutrient water a way different one, that could be the main reason why they are looking like they are now --> high fluctuation in PH (and plain water ph beeing to high for the soil to buffer) From now on: --> TEST PH (!) Best case i'm gonna check every week when changing according to feed chart. --> Adjust the PH so that every watering is around the same level. Best between (6.5 - 6.8) --> When cutting on fertilizer, give less nutes to the full watering. Don't give them half/half. --> Have some PH Strips around in case of emergency Lots of learning for one week. Remember: The idiot always sits in front of the tent. Day 73: PH Pen arrived yesterday (and some PH strips for emergencies😋) Feeding Day: 1l each (still a bit moist) with a 6.6 PH. The ladies still look rough, but at least they seem not to feel horrible and the rusting has stopped/seems not to get worse. And they smell delicious. Phew! Fingers crossed! Day 75: Still looking like the rusting stopped. There is hope :D Day 76: Feeding Day. 1.5l nutrient water for each. PH 6.6
