What’s going on? Plants are dying??

[asbrg]

Hello,
First time growing here! I don’t know whats wrong with my plants, leafs changing color and tips drying.
pH: 6.5
Im following the recommended dosages for the nutrients as also for the watering.
Im using an CREE COB LED 1000w
Nutrients and soil as shows on the photos.
Whatt im doing wrong? Any thoughts? Cheers

Light stress imo - 1000w of true draw? What heights and intensity are you at?

I did attach the photos from the tent and lightning that I’m using. Although this start happening soon as I water the plants, mixed with the nutrients. Is that a chance of excess of nutrients?

Its 280/320 watt light and it way to close.

Looks like what you see when you get a warm dry environment and to much light.

You dont have a fan on them do you?

Thanks for your feedback lads, I will consider ordering different led lights and give it a try..

Just back them off

I can’t.. too small the tent

I just switched off the ‘Boom’ button, it seems less intense the light and less warm now. I’ll wait a few days by the meantime and hope for the best

Of they are at the too then i am wrong avout the lights and just goes to show i should have asked a few more questions.

How far from the tops of the plant is the light?

How much of what nutrients are you giving them and how often?

I feel a bit foolish now lol. I always say light stress or any symptom can be from different root causes and yet i just assumed… sorry for that i have just ran into that exact root cause many many times recently

How deep is the soil? I cant tell with the hydroton on top?

im following the nutrients dosage as mentioned on the guide attached. The soil is about 5inch deep. Plants are about 90cm distance from light

Some of these cocobricks are heavily polluted with seasalt which in turn can make your plant wilt and not absorb the right nutrients. Some of the leaftip necrosis looks like it (Na toxicity)

Also, claypebbles often come unwashed and way too alkaline. Both could lead to a situation where Mg and other minerals can't be absorbed much anymore.

One way to find out is check pH & EC of slurry of your materials in distilled water

In headed out @N1ghtL1ght may be on to something. I feel like more than one cause here and personally id pull the hydroton out and fill with the soil. Layering media can cause issues
