Came Back To This...

Did some fim'ing/topping/supercropping a few days before going away for 3 days. I also changed the light from a 110w floro to the 300w MH. Set EC to 400 and pH to 5.2 the day I left, and when I came back it was EC 500 and pH of 7. They get flooded every 8hrs, and air temps are around 23c 74f with RH around 50% and rez temps around 66f

The two things I'm thinking is either over watering, or maybe the containers are too small? My dehumidifier filled up and shut off within 24hrs of me leaving, so when I got home RH was 69%. Not many roots coming out the bottom of the containers, but there are a few. Also the canoeing leaves kinda look light green and almost the start of zebra like.

I want to clone ASAP and flip 12/12 but want to make sure they are healthy first.

Any ideas??

Thanks

I think the plants are overwatering. or heat stress....
If u watered more than once a day....
And if u use clone u just need to use fresh water
