I think you answered your own question,your plants look like they need a few more weeks and you flushed out all their food.

Thanks for the reply myke though wouldn’t they still be feeding off the remaining nutes in the coco at this stage

Coco and flushing is a quick thing. you have to keep coco soaked for it to retain anything. so flushing will just wash away ALL of the nutes.

Try tapering down your feed. Feed them next time you water as you were then reduce each watering.

No need to use just plain water when the plants still growing bud...

Why are you flushing those plants? From just what I can see in those pictures it's obvious they need at least another couple weeks. If you're going by the the strain description to determine when to harvest, don't. Go by the plant. I see lots of white pistils. And never run plain water through coco while the plant is in the process of bulking up the buds. Those plants are in the process of swelling and now you've starved them of food when they need it. Next watering feed them and taper down the strength until harvest. Even if you do flush you don't do it weeks from harvest when growing in coco.

Good luck with your plants and harvest.

Agreed with all of the above.
Plant is starting to eat litself because it has no food.

Thanks for all the replies guys I just feed them though they only did go one water without food so would that cause the sugar leaves to brown that quick also I was unaware I didn’t have to flush everyone was saying I had to flush for 2 weeks

Coco isn't like soil. It's inert. It has no nutrients in it. You don't want to starve your plant for two weeks. Anyone telling you to flush for two weeks in coco doesn't know what they're talking about.

Where did you get the Strawberry Kush? I grew some I got from ILGM several years ago that was some really nice smoke.
