overwatering, or heat??? What kind of temps in the tent??? Might have some root rot…, no expert here.
Watered yeseerday an this is todays outcome
clawed leaves, bulging viens
cold soil, over watered, wrong temp to RH so plant cannot breath
more info would help to figure it out 
Yep… It looks like too much water, I agree with above. 
Agree, overwatering is the MOST common issue with new growers and i include myself in that group best advice i can give is take a pot the same size as the plant is in and fill it with whatever soil your using and use that as a weight gage lift it and should feel fairly light ( loaf of bread light ) then lift your plant if it feels heavier than your gage then wait to water, this has worked for me fairly well. 5 gallon pots for me get watered every 3-4 days usually with around 1.5 gallons of water more if in flower. Stay lit my friend 
Let em dry out, should be fine maybe try a fan aimed at cloth pot to help drying her out
Thats classic over watering. And poor drainage. The plant is drowning.
between watering is great advice the plant likes a good wet dry cycle
constantly moist roots in soil/soil-less will not lead to a happy plant
but without real info we are all just guessing
the wrong VPD will make your leaves look like that also your plant is drowning
Lol yep needs a lot of perlite. More porosity
and vermiculite to cut the roots for a dense root mass
You know i have some coarse vermiculite and some dolomite lime.
Thinking about dr. Bruce bugbys grow media at Utah state univeristy.
He advises to use 50% vermiculite and 50% peat moss for explosive growth (a bit of gypsum and dolomite added in only).
went through this at the start of the season 
wanted to put my
MH/HPS lights back up and move on sell off my LEDs
my air temp was way too low so my leave temp was too low
the VPD was way off so they look over watered but it was the fact that
the plants had no transpiration
drowning so after reading how to actually grow with LEDs I glad I did not get
rid of them
my power company is sad
Vermiculite adds a lot to any soil/soil-less mix it buffers, it cut root, it holds water
and nutes
all the best and grow well
