Any idea what this is?

I’m not sure what could be causing this, I’ve flushed it and put it on reduced nutes last week but it’s not loads better, if at all. I’ve ph it to 6.7 run off but my pen isn’t great, even when I calibrate it it can take 5 minutes to stabilise and can seem stable at 6.5 but then continue to 7.1 in 0.01 increments. Anyway, any input is greatly appreciated.

first get a good reliable and accurate PH meter/pen then go from there. Im guessing that you are growing in soil and not coco. If soil, you can try upping nutes and give them a few days to respond.

Looks like it is pulling all the mag out of the medium. A few calcium spots too. I’d raise your light or turn it down. Hoist light, 3-5ml cal mag a gallon. You shouldn’t flush in soil.
It causes issues you wind up chasing all grow…

this approach is a better suggestion than mine.

I'm playing around with my new nutes and have been feeding my babies at half dose. They are so hungry, they are almost glowing. Next feed going to full dose. I'm in same boat as this guy. It's okay more nute will fix.

Yeah flushes are bad mmmmkay.

Intensity of light and how close? I have a feeling your PPFD is too high for the stage you’re in and causing decencies faster than you should be, like @Captspaulding said

Hard to tell about the light from the pics we have. From what I can see it's looking like leaves are fairly flat. I would need more pics to put in my two cents on light distance. I'm not as good as captspaulding, but he knows his stuff so wouldn't disagree.

The fact that it’s light in color, and showing calcium already, at that stage of life tells you everything. Bit young for all that. That’s why I’m leaning in the direction of the light. Also nutes, gotta corral and dose that medium post flush. But 9 times out of ten when you see these symptoms, esp the cal showing already….its light driven generally. But the flush here makes it a double wammy.

not sure on ppfd, but the dli is around 30, using the photone table it says they should be at 40/50 by now but when i increasse the light they have got stressed.

sounds about right. Yeah. Crank it back down buddy. You’re close to dialed in with it.

thanks for this, the dli is 30 and the photone app says they should be at 40/50 by now, ill look at raising the light higher and will add more call mag.

thank you! ill reduce the DLI.

Np homie!

Few grows ago I had a similar issue getting used to LEDs. Yours are similar in issue so that’s why it reminded me of a possible DLI issue
