... I'm killing my baby...

First-time grower using autoflower seeds. Pretty far along in the growth cycle expecting to harvest in the next couple of weeks.

I read that when growing in soil flushing is a good idea. Pulled my nutes and in flushing with ph balanced water (7.2).

Suddenly the plant is yellowing and dropping leaves. Wasn't worried about the lower fan leaves but now even the upper leaves on the main cola are being affected.

Tips of leaves are curling up. Light source is a good 20in away from the top cola.

Attaching photos for reference.

Any help is greatly appreciated.

No where near ready to harvest or flush

Ok. ... That might explain it then.

You have a min of 6 weeks and flushing is pretty much pointless

Woooh. Ok I was way early on my timeline...

I appreciate that input. Will make sure to get them back on a feeding schedule.

You're seeing nutrient deficiency. Yes, start giving nutes again. Also, a pH of 7.2 is a little high. You want to be more around 6.5. Some nutrients might have trouble travelling through the plant if the pH is out of range. This could also make it look like a deficiency.

When growing in soil, you're supposed to give straight water every other watering, until you get 20% runoff. When flushing, it's not necessary to balance the water.

dont flush

You flushed ( leached ) their food away .... stop it.
Feed them and let them go ( without messing with them ) for at least 6 weeks.
Hopefully you didn’t stunt it as autos hate stress and want to to just grow.

BTW, I wasn't implying that watering without nutes every other feeding was flushing. I concur, don't flush

Good luck, think you'll stunt them and produce little yield, autos are on a time schedule from the second they crack open.
