HELP ME PLEASE!!! My PLANT IS DYING!

I need help with my plants, i dont know what the problem may be.


Setup:
HPS 600W 24/7 thats been on since they where seedlings.
Good Ventilation, big space.
The plants are about 40-50 cm from the lamp.
The temp is about 25-28c.
They are being watered every two days.
The soil is proffesional growing soil. .

Everything has been going fine until this last week, they start to dry at the end of the leafs, getting yellow, and stuff like that.

Fast answers are very good ;)


Sorry for my english.

Overfertilization is my opinion, flush it out. looks like nute lock.

Allright, so by flushing it will it automaticly solve the problem if it is nute lock?

I dont think it will hurt. You should only be watering with fert once a week or every 2 waterings.

but the problem is my soil aint fertilized..

I have used professional growing soil.


I dont add fertilizer & nut in my water,

it have worked fine untill last week, they are still in VEG 4 weeks counting.

fill out the trouble shooting guide on top of plant problem page.
