My plants have 14 days, they are 4 Pandora`s autoflowering from Paradise Seeds,

I use a 400w MH bulb on a hydroponic flood and drain system.
I build my system from zero.
I use Flora Duo nutrients and roote accelerator.
The ph is around 6, I use filtered wather and lower the ph with ph down...
The temp is around 30 degrees Celcius, but i try to lower it by venting the grow room.
The lamp has a 33 cm hight from the tips of the plant.

My plants have some problems, the lower leafs are crispy and yelow between the nervs ... I don`t know if a nute burn or a problem from the heat,

I`ve uploaded some pics...

Please help,
Need advise quickly

Thx,
WhiteWidow

Do you think follial feeding had something to do with that burns ?
I used 1/4 strenth ...

It`s my first grow ... and i thought hydroponic was the way :D ... and I still think that ...

I don foliar feed, but then again being a medical patient imm all about Recreating a natural enviroment for my plants for best quality possible, but I think cuttin bac nutes will help also

Flushing prevent chemical bonds from formin in you medium that lock out nutriens to The plant... Should be done weekly IMO

Yea, only time I spray my plants is with a miticide.
Ya know, after looking at that one pic with the leaf edges curled a bit it may just heat stress but I still think you are better off at half strength nutes.
