Pistils turning orange very early into flower.

Cheebatrees · Dec 27, 2021

Hey guys, so I’m running a 2metre squared tent with two LUXX lighting 645 pros, a 16 pot Medusa run to waste system, 15litre pots dripper fed for 10 minutes four times a day with Athena blended line. Two Exhale co2 bags in there. Input ph is 5.8 EC input is 4.0 and run off is 6ph and 5.4EC, Ppfd at the canopy is sitting between 900-1500 (multi strain room so I have a couple of low growers) day 23 since flip, and after foliar spraying with Athena stack and Power SI 5 mins before lights off I noticed this morning that some of the plants pistils have retracted a little and turned orange. I understand it could be a multitude of things but I’m abit stuck. I thought it may be burning from the foliar spray or heat/light stress but the plants that are closest to the light are completely fine, still white and reaching. Also would love to know if they’re looking good for the stage they’re in! Im a rookie and this is my first time running this system. Only second run ever. I’ll attach some photos so you guys can have a look and hopefully I can get to the bottom of this before there’s any (if any) damage done. Any help would be super appreciated as I’m driving myself a bit mad trying to figure this one out

EC seems too high.
