Hello, could someone please help me diagnose my plants? pH around 6, using GH Flora trio and supplementing with a small amount of Silica and CalMag. I'm noticing yellow patterns on the leaves and occasional curled/twisted growth. My hunch is that this is some kind of virus, but I thought I might ask if anyone else has input. Thanks!!! P.S. I can post more pics with lights off if that's helpful
Lights? Medium? Actual amounts of each bottle of GH per litre or gallon of water?
Also, you say your pH is "around 6.0". How close is "around". The pH scale operates on an exponential order of magnitude basis. For example, a pH of 6.0 is 10 times more acidic than a pH of 7. A pH of 5.0 is 100 times more acidic than 7.0. So being "around 6.0" isn't good enough for determination of whether you're in the proper range for your medium (as mentioned, we don't know that either).

Not viral, your actual symptoms are discoloration, slight clawing and margins slightly upturned.
I don't work in hydro so others will know more about nutrients and if they're right or wrong or just need tweaking.
Upturned margins are a sign of heat stress, so if you factor that in then you only have to worry about slight clawing and discoloration.

How far off the canopy are those lights? If I recall correctly, the QB96 needs to be spaced a lot further away from the plants...more like HPS than LED. I could be wrong, but I could swear that was a very powerful board.
Hi! Yes they are potent boards, but I have a lux meter and they are only at 15K lux right now, which is more of a seedling level from what I'm told. But good point, I will definitely keep an eye out for light burn signs as I had that before--thank you
Thank you for the input!

I see no indications of viral issues either. Even when it does potentially pop up you cant really go oh that's a virus. You cant really self diagnose it very well. You have to send it off to a lab to be tested. I've sent off many samples back in the day. Even when it looked viral in appearance the test results would often come back negative.
Great point. Based on the photos, does it look like a nute issue to you?
