What deficency is this? Sill adjusting to Gavita 1700

[mcaveman]

Using Botanicare bloom 15 ML , 5 ml calmag, 5ML karma. Plants are Bluedream CO2 1200ppm . Humidity 60 leaf temp 75F. Media Lamberts LM-Org

What a learning curve going from 1000 HPS to these lights, can wait unti I get this dialed in.
Last picture is from a big ole mother I threw out in room the other 3 from the main crop, plants are about 18" tall 2 weeks into 12/12
Thanks !

Looks like you're driving them too hard. Too much light and Co2. What are the room temps and how close do you have the light? Is it on 100%
Also what media are you in? Do you have ppm and ph feed numbers?

 

[mcaveman]

Lights are far up as possible about 44-48” away . PH around 6.5 room temp 78 leaf temp 75

you cooked them.

Also to me...severe light burn

Good news is I just got the controller I will install lower % and report back . I though 4 feet was more than enough .

I forgot to mention with my cheap light meter is showing around 16-18k lux at top of canopy.

Those 1700s are fairly strong. We run way too many lights. Fluence, gavita, kinds, gavita hps. The 1700s definitely can't be 6inches over canopy like spydr x plus. We ordered some photontek 1000s, another 1 to familiarize with. I think it is a good idea to dim them.

Light burn and what looks to be bad pH.
If you can't dim them, turn one off.

Thanks y’all I’ll update in a week or so

It was definitely the lights , got the controller and have them running 66% , much happier now.
