Hello can someone help me diagnose my girl

[sevare]

Temperature: 68-70 degrees
Humidity :70-72
Cal mag: 2-2.5ml per gal
Micro : 8ml micro per gal
Bloom: 16ml per gal
Using RO water
1300-1500ppm

From what you've provided, ppm seems high and temps seem low, especially if you are running LEDs. What are you growing in?

 

[sevare]

I’m growing in coco if the temps are too low I could remove my intake fan which is pulling air from outside

 

[AKgrow]

With LEDs the plants like closer to 75-80 degrees ambient. I run around 74 without problem. Cold stress will affect nutrient uptake and present as deficiencies. Also, your ppm seems high, could be causing lockout problems. Even in full flower, 1500ppm would be too much, 1000 would be pushing the plant. I'd shoot for closer to 750. Unless you are using a bunch of co2 and everything is dialed in right, then maybe 1300-1500ppm feed, maybe.

Turn your lights down or raise them. See how the edges of your leaves are turned up? The dead material on the leaves is also the burn pattern I've seen when I fry plants under LEDs.

 

[Imzzaudae]

Definitely light burn.

 

[sevare]

I have it at 24 inches. The burns are progressing more

raise the light and get your temps closer to 75/80f like it was mentioned. I use outside cold air as well to bring fresh air in. Works great, i wouldn't touch that, maybe a heater would help. Also, couple fan to blow the heat from the light would help.

I think I fixed the temp issue I’ve been getting 70avg and my humidity has been 50. I’ll try raising it higher. Maybe 30 inches?

ya, 30 inch would do for now., We can see how they react and then either turn intensity up or leave it where it is at. What is the currently intensity setting at?

 

[sevare]

I just turned it up to 100% when lights came on 30 mins ago. And it was at 70% while in veg

You growing in Coco? Add a small amount of cal-mag every watering.
Coco eats magnesium and you have to replace it.

What are your ppms in and out? pH?

Yeah I’m growing in coco! So maybe drop my cal mag to 1ml per gallon?

How much and what do you feed?

Watering COCO

HOW TO WATER COCO FOR BEST RESULTS.

Ok writing this cause i see this issue often and rather have a thread to link than explain this each time. This is not my work but a collection of info from many members here and I have put into practice myself. So first off COCO is NOT soil. For best results we want to keep it saturated...

2-2.5ml cal mag
8ml micro
16ml bloom
Then I ph to 5.8-6
And i feed until runoff
I’ve been feeding every day sometimes I’ll forget to feed a day and it turns into every other day of feeding. But that’s only when I’m sleepy

Leave your cal mag where its at and cut the other 2 in half. Too much of them will lock out something else. It's got to be a balanced feed.

 

[sevare]

I’ll try that

Looks like a lot more is wrong then the lights. Can’t really help much (Dirt here) other than to say I have plants 4 inches, yes 4 inches from a 540watts illumatech burple at 95% and there just fine.

I love soil for that reason. It's all auto balanced and you can really push them.

Can't do that with Coco. It must be fed and watered daily, maybe more.
