Help - My plants don't look right!

[DoN2tm]

Hi there, iam quite new to the whole community so please bear with me on this one..
my 2 girls are looking abit droopy after i watered them (with nutes) they began to have that depressing look to them as you can see from the pics and they have looked like this for a couple of days.. initially i thought maybe they got nute burn as the leaves seem crispy?

today 3-4 days after feeding i watered them (got desperat) so i gave them a good flushing to see if that would help, but dosent seem to make any difference atleast not yet

the temps inside the tent are at 27,5 Celcius (81,5 fahrenheit)

i use biobizz veg atm at the recommended dosage..

hope some of you more experienced people can help me correct whatever iam doing wrong

What's you set up ?
Medium ? Just the pebbles ?
Hydro ?

ohh yea sorry about that.
my setup is soil with thoose pebbles mixed in for drainage.. also the humidity is around 40ish at all times..
the girls are in a 2x2x5 DS60 tent with a Marshydro 300W led (old model)

i use plain water every second watering. and between watering i spray them a couple of times with water too ..

the leaves feel really crispy somehow and noticed that some of the lower leaves where all yellow. mainly the first set of leaves

My guess would be low humidity and over watering
Are you using the pebbles to stop bugs ?

 

[DoN2tm]

Well actually iam using the pebles to help keep the surface moist longer, and of course to keep bugs from going to the roots ..

i cant understand how i can have overwatered them, iam giving them water until i get a drain off and then i stop .. i guess that flushing earlyer today wasent a good idea then ?

just noticed some of the stems on the leaves are abit purple what is that all about ?

Over watering in soil is done by not letting the soil dry out before watering again
Leave them for a few days then check top of soil about a inch down if it's dry water if wet leave until dry then water
