2nd grow: indoor autos RQS/Barneys/FB

Day 49: Last week was full of issues. The Leaves of the Crystal Meth got much worse and i have no clue what is causing it. (But some hints, thanks to you) I still try to figure it out. She will get a good flush tomorrow and then we'll see. But the other two are quite stable. They still are kind of droopy, but better overall. Maybe i flush all three once just for a little reset and see how they react to it. Sooo i guess this will be the strategy: 1. I'll give all of them a flush with 6.8ph water, to get the perfect spot. Just in case its a nutrient lockout (should not, because i always checked ph when watering) or nuteburn (could be, not sure if i messed up there). So that could help with these problems and should not do big harm to the plants. 2. If they do not stabilize i'll give them additional cal-mag, in case its a calcium or magnesium deficieny which may occur more often with LED lights. That may be bro science, but i remember to have read that multiple times. 3. I try to treat them for rust fungus, septoria or or such fungi. Its unlikely but i got high temps as well as high humidity in the last weeks. I got very good air circulation, but the other circumstances and symptoms would kinda fit. I guess the problem is most likely wrong watering, wrong feeding or a combination of the two. Of course there is the heat, the humidity etc. (but i don't think these factors cause symptoms like this) Day 50: I flushed them all with 10l of plain water with ph'd water (6.5-6.7). The hulkberry holds noticably less water than the other two. I just let them chill for a few days now. Temps sit at around 26-27° and RH is between 40 and 50%, so they should be quite comfy for them. We'll see. Day 52: The Flush did not seem to help much. Pineapple Express and Hulkberry got much more yellowing in the two days since the flush. So i guess they are deficient. Gave them a little feeding (soil was still not dry), not ideal but i guess they are hungry. The crystal meth i'll leave as is. The flush didn't seem to harm her and the symptoms did not get way worse i guess. So i'll leave her drink up and will feed when she is dryer. But before the next feeding i'm gonna check her trichomes. If they progressed more than i think, she will just get flushed until the end. Day 54: I think we maybe stabilized a bit. The yellowing situation did not get much worse and was slowing down. So i think the flush und reintroduce nutrients were not a bad move. Crystal Meth is showing a 50/50 ratio of cloudy and clear trichs, so i will feed her one last time and then let her finish with water only. Pineapple Express started to notacibly fatten up her buds, while the hulkberry is a bit behind.
