New grower having trouble.

This batch has died (or VERY near) now but i would really like to know what killed them.

I planted 4 seeds that one of my mates found is his batch that was bought off the street. (Wasn't expecting anything good lol)

I am expecting you all to say that it was to hot for them as where they were located was near impossable to regulate the heat.

Anyway onto the details. My crop was 5 weeks old and they started to yellow around the outside of the leaves. Where they were kept the temperature was around 22C with the lights off and around 30C with it on. The humidity of the room was around 44 and 55%. The light that i was using was a 400x Grolux HPS light that was on around 18 hours a day.

Here are some pics of them around 2 weeks ago. Since then the leaves had turned totally brown but there were new green leaves forming still so i assumed the plant was trying and cut the dead ones off so they wernt wasting energy on dead leaves.

I think you are giving them too much water ?
do you let your top soil dry a few inch before watering again ?
Do you know the ph of your water ?

Defiantly nutrient burn, I can't say this enough, water them with mineral water & cut way back on the nutrients. Also you should put a fan in the room to make the main stem stronger.

Thanks everyone, got a lil more information here to mabe solve this finnaly because im kinda stuck between MORE nut's and NO nut's :p

well, here goes. The soil i used was B&Q multipurpose Compost for general use. I mixed the soil to contain like 15% perlite. The bulb was around 60 -70 cm above the plants. At first i was feeding them rain water for the first 4 weeks. Then i moved onto tap water.

Hopfully this helps.

Thanks again

For sure they need nutes.
But my guess is that your main problem is you're keeping your soil too wet.
which is causing a lockout of magnesium.
Let them go dry a little and give them some nutes which contains all the
macro and micro elements.

You must know it all then, buddy said he didn't feed them for a month! That isn't nutrient burn because no nutrients were present to burn it!!

Brown leaf tips can be a sign of too much nutrients or two little, without actually checking the pant out is not as easy to make a diagnosis just looking at a pic or too. The chlorine in your tap water if too high can also cause this problem. Also can be a sign of too much heat. But I didn't come hear to argue, just to share my 33 years of experience.
