Need some assistance. In veg. Around week 3. These plants looked good until 2 days ago. Feed them a gallon of distilled water each last Sunday (1 week ago) with no nutes. Soil meter shows soil still most, but then again that was the whole pot and roots near the top. These are Runtz autoflowers. They looked healthy all week and then hit this rough time. Lights are 24" above and Mars Hydro TS3000 at dimming of 75%. Temp around 79-82 & humidity around 60-70. Lights on 18/6. Fans on 95% of time light or dark. Just couple 20 minute rest breaks during night. The plants seemed to be extra dark green before then shriveling up like this and developing crinkly leaves. My first ever grow. This is Fox Farm Ocean Forest soil. In there since they were seedlings. Solo cups first 2-3 weeks.
This morning I gently removed loose soil around roots and sprinkled alot of Great White mycorr all over the soil root area, lightly covered with soil and soaked. Also raised lights to 30" yesterday and although there is some fan breeze hitting them, it's not a ton like the other side of the tent gets with my photo period plants that are coming up nicely.
Please help me save these plants!

They look either overwatered or under watered. That 1gal of water in each pot was probably too much. It's been awhile since this post. Have they gotten better?
