What is this ? is this a deficiency at week 2-3 flower?

growing in biobizz light mix and biobizz coco

ph at 6.3

advanced nutrients but using half doses so i taught it might be a deficiency , or nute lockout ? i always feed 60% the recommended dose at ec 1.5 but i dont usually have runoff all the time , do you think i should feed normally and give more water volume so i can have more runoff to flush or just give cal mag with water and let the irrigation run until i see run off from all the plants ?

I think yourpower output settings are roasting your plants. Fairly certain you should turn them down.what are they set at?

they are at around 20 inches at 60% on some benches ,and some others maybe 16 inches at 70-80% but they keep stretching and the ones that are closer to the lights are not affected at all , its all at the bottom ,im using SE7000 (730W)

I don’t veg past 45% output at 30 inches above canopy. Those lights are crazy powerful. The nutrition you have them on is fine. That’s why I’m leaning towards that being the issue. I run spider farmer se series and g series.

the ones that are affected are at maybe even 30 inch + away at 50-60% so 350 watts which is not so much with 550ppm co2

Alright. Fair enough. Well take some surface temps if you can, the leaves curling on word on the leaf edges is heat stress.

Also, if you look at the damage on a few of them pics, it almost looks like griddle marks on the leaves. That’s nothing I’ve ever seen before, looks strangely like light bars……

if its not the light , what could it be ?

 

[Captspaulding]

Not sure. I never water to run off.
AN at 60% strength is good for that stage of growth. I use that as well. So not sure homie.

do you feed all the time , or u do just water intervals sometimes ? like feed - water - feed - water ?

With the set up you got, purchase a quantum par meter. It does look like light burn. I've had the same problem before. Until I could measure the light properly, didn't really know what intensity.

I would begin having similar issues around the same time, 2-3 weeks into flower. I was using Fox farm bottled nutrients and not usually getting any run off. I figured my problem to be lock up due to build up of salts after some research and flushing. After a good flush they came back some, but the next round I watered to run off when I was only watering and not feeding, and it cleared things up. I haven't read through the thread yet, I'm curious what others have to say because I always thought there was more to it.

Feed every time yes. In soil it’s always how I roll.

i thought since the leafs at the bottom are effected and not the ones closer to the light it might not be ? but you could be right, im gonna dimm the lights down

Legit though, I’m pretty certain it’s a light/heat stress situation here. What is you air circulation looking like? You have the air moving well? Good ventilation?

yes but i need to impliment some more fans coz i can still find water on leafs where its abit compact
