Leaf diagnosis? Heat issues?


#1

What’s up everyone, my girls are doing nice. Was wondering if anyone could help on telling my what’s going on with a few of the leaves? I was thinking heat but would like some more opinions! Happening on 2 out of 20 plants
3 1500w lights, supplementing co2, LST, all autos. 3 fans no ac.


#2

Is it a led light what kind of light is it. At first glance looks like heat or light intensity issue


#3

I have 3 1500 watt BESTVA leds full spectrum


#4

How far away from tops are the led lights. They need to be atleast 18 to 30 in from tops that is always a issue and what’s the temps in room


#5

the ones with the leaf issue are aprox 16-18" from the lights I have much taller ones with no issues showing at the moment, just raised my lights tho. temp is low of 73 high of 88.


#6

It appears to be nutrient toxicities.


#7

Nuit toxicity temps are a bit high u want 77 lights on and 65 to 67 night get heat under control first you will se it looking better in a few days and don’t put nuits in for at least 2 feedings let her use what she has also rh in 50 to 60%

Can you fill the support ticket out please that @Growit posted
I suspect @Dumme is on point here
The lights should be min 18 inches but i don’t believe raising them will correct the issue

More info please :v:️ CB

@Dab The reason the tops look good now is for some reason when I used led you never see symptoms on the new growth will look good but when the intensity dose start to show issuers on top growth it will stunt and even kill the ladies so keep a really close eye on it ok also temps are way to high 77 max in day 65 to 67 at night rh is to high u will get mold with rh that high during flower especially. You can get mold anytime with rh that high but you will ruin your whole grow if you don’t get temps and rh in ck asap


#12

@Dab I see your not useing venting easy fix for temp and rh get a exhaust fan to pump old air out and new air in and it doesn’t have to be outside air also you might want to think about a co2 bag to hang in grow area. But the heat and temp fix is all in the exhaust


#13

Thanks for the advice! I have a co2 tank 20lb in my room but will deff have to get a AC or vent fan ASAP! I’m using a spare room so I can’t open the windows due to neighbors have plywood up over them as of now so should I put the tubes from the vent into the adjacent room?


#14

Yes so you are venting out the room and use a carbon filter so you could vent without the smell that will help with the rh. how big is the room you grow in so we know what size fan you should get for exhaust. And the fresh air will come in from underdoor and in any air gaps you have in room. Main thing is to make sure your exhaust fan can flip air in room in a few hr fan to small it won’t exhaust fan to big is waste of energy. So again room dimensions and if all windows are blocked might want to slit a spot in ply with a flap over it to keep light out but let fresh air in. If air can’t get in it can’t be exhausted out you need air to replace what you are takein out. That’s how air flow works lol but you might not need to worry if there are gaps for air to suck in


#15

Room is 18x8x8 I left a 3” gap in the plywood so I could use a vent if needed but how I have it set up now it lets no light out but I’ll have to mess with it deff need to bring the heat down!!! Would a ac or a vent be better not to concerned about price just want the best buds I read when supplementing co2 you can run the heat higher to 85 but again just what I read.


#16

Ok ac will do best but it won’t draw air in it only Recycles what’s in there so that’s the point of exhaust. I would get a exhaust fan first they are cheaper then a ac and the size exhaust fan I would get is like 250 cfm I’m not sure the size exactly I’ll hit up @Countryboyjvd1971 he might know exact size exhaust you will need and that should fix temp issues and help with the rh becose heat cold and rh are all interweaves with each other like you will notice your rh goes up on lights out not on lights on but your on the right path


#17

IPlant is doing worse :frowning:
