Seems like overwatering/feeding. 1L a day is a lot and doesn't allow the soil to dry out before you water again. You should only water once the top inch of the soil feels dry. (stick your finger in to the first knuckle)
Cut back on the water and that should help. Weed likes to have at least 2-3 days between waterings!

Plant seems to be dying, should I flush? And if so, any tips?Yellowing & wilting, I suspect the problem is too much silica boost .5ml every other water, combined w/ hot soil (FFOC) & a few feedings, & maybe underwatering(?) as I never have runoff, watered a cup or so every ~48hrs, when soil had dried. LST, no wild temps/hum, great airflow.Leaves. Curl down

I just did a top dressing less than a week ago I used feather meal kelp meal alfalfa meal and some bat quano. Looking at charts it seems to be a nitrogen deficiency. I know feather meal is slowWeek 4

Triple-leaf Speedy Chile: what is growing there? Why becoming yellow?My triple-leaf Speedy Chile (see also week comment for more info): 1. The 3 cotyledons have become yellow. I also see on lower leaves slightly some yellow tips. Nutrient deficiency? Underwatering? 2. What are the small leaves coming out of soil. Another plant? Should I remove?a year ago
