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.

Strain is mostly white russian, but there is som kush, blueberry etc.

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.

I agree it dose look like nute burn.

check your roots could be rootbound

Not nute burn. Extreme hunger. Calcium deficiency (water possibly too soft?). Too much stretch due to red spectrum light instead of blue.

Add blue-spectrum light from 'daylight' flourescents right near the plants or from a Metal Halide lamp. This is better for vegging. HPS makes young plants stretch.

You NEED to feed the plants! Use a cannabis-specific fertilizer like Botanicare or Canna- there are many on the market. HAve your tap water tested for hardness at the grow shop and if it is below about 200ppm you will need to add calmag plus up to 250ppm to make up for the lack of calcium in the water. If you want to avoid this, use a potting soil that has plenty of lime in it and make sure to re-pot FREQUENTLY into just SLIGHTLY larger pots.

DO NOT flush those plants at this point; they are already starving.

thank you for a very good answer, !.
Cant i just add som egg shells in the soil*?

No.

So add calmag up to the point of 250ppm? Is this an ideal ppm for early stage plants (under 1 month?) Or just for nute mixture to avoid lockout?

I swear I have the same issue.......first transplant your plants into some 6-8inch potters.

Looks like a fungus....black spot....thats what I have

the first few pics looks like magnesium deficiency 2 me, but im no pro.

Vaped g13 you already have a thread about that problem, posting it here is confusing especially since all your grow info is elsewhere....
