Plants need help (pictures)

hi my first time growing and have some problems.


im growing indoors and watering 3 times a day using technaflora. alot of the leaves are turning like this.

and my small plants leaves are turning yellow at the bottom of the plants




thanks for your help

3 Times a day?! are you insane? you're only supposed to water them when the soil isn't moist enough.

*Edit* Actually wtf.. that isn't soil.. lol

thats rock wool and another growing medium. do you know what your ppm and ph are at.

We need to know
PH
PPM
Air&Water temps
Light Schedule
Age of Plants

Three waterings a day still may be a lot, Im not sure, but...
Yellowing bottom leaves are a sign of over watering, it is also a sign of Nitrogen deficiency.
I also suspect a PH problem by the looks of some of the leaves... (Something is being locked out)

Maybe you meant to say that you water your plants once evry 3 days. That would sound a little bit better. Watering your plant 3 times a day is equivalent to you personally drinking 15 gallons of water a day. You would probably start to curl up a little bit and there would be a possibility that you might turn yellow as well. I'm not claiming to be anywhere near an expert, but I think you should stop whatever you are doing and read up in this forum. You plants lives are hanging in the balance!!!

This setup is a hydroponic setup using grodan rockwool cubes. and i water 3 times a day not once every 3 days. I dont have a ppm or ph reader yet so that might be the problem. the room temp is around 85 degrees and lighting schedule is 18/6 for all my plants right now. the top 2 pictures are 2 months old and bottom 2 pictures are 3 weeks old.
