I switched my plants to flower about 6 days ago and one of them have there leaves starting to curl and get brittle I have had this happen to only one plant in the past but I am not sure why. I grow in DWC and my ph is between 5.5 and 6 running with general hydroponics flora series temps stays around 85 and humidity is around 50% and I use RO water as well
This is the only plant out of 3 doing this

Any help would be great

Without knowing your whole setup, I'm wondering if it's just something silly and simple like the air line to that bucket doesn't have enough oomf.

I have a 4 port air pump running and full power to all 4 buckets

And this only happens in the flowering stage and I can see the air bubbles coming up from the bottom of the bucket

Could it be are flow

The lights are full spectrum led I can post a picture of the distance of the lights to the canopy in about an hour when I get home the strain is permanent marker the DWC is ran with a water chiller they the temps stay at about 68 degrees and I can get the ppm or ec when I post the other pic of the lights as well

Could it be not enough air flow. Could that cause this problem

Tent temp stays around 85 and the humidity 55

This is only happening to the one plant out of 3

We understand that only one plant has an issue but we still have to review the grow to rule out issues.
Seeds produce variations in cannabis plants. Some can take more light some less and some can take more nutrition and some less .
Seeing a trend in EC can tell us if the plant is drinking or not and up taking or not.

But seriously we can help but we need enough info to help you or we are just throwing darts.

Yes and quickly but you are not done.
Did the level in the bucket drop fast and leave you with a hot nute mix or did we have a bobo and mixed it wack?
Look for new growth looking good. Damaged necrotic leaves should be pulled.
Best thing about cannabis is the lower growth matters less after you rebuild the plant.

Just watch new growth and keep monitoring keep a log! if ec drops they want more if it climbs they want less
