Couldn’t be, I watered her like 3 days ago after transplant just around the brim though. I use happy frog and just ro water it’s only one giving me trouble after transplant the others are praying ohh they’re under 200 watt cobs....
Flush as in dumping a ton of water through the soil completely saturating it leaving the plants roots drowning and stressing it even more? I wouldn't. Just give it plain water for awhile. There are enough nutes in that soil to keep the plant fed for the near future.
