(check for insects)
how high is your water level/ how much gap between the pots and water?
looks like cal mag if its nothing else, if it doesn't get worse I would ignore, hydro plants are more sensitive to changes in nutrients and usually when switching the water res it is a bit unstable for the first few hours/day so this can end up looking like ph fluctuations and light burns.
your leaves are nice and dark, tips seem nearly to curl in, maybe try slightly reducing the nutrient dosage and see how that goes?

The problem is that is is getting worse. What kind of insect could cause this? (If that’s what it is). This website also doesn’t seem to like to have people contacting eachother because I can’t answer questions without “giving an answer”.
Like I said, pH has been stable, and they eated alot. pH from 6.4 to 6.1 and EC from 1.1 to 0.8. The tank that feeds my RDWC has water of 5.5 and 1.3. So nutes and “pH down” get slowly added in RDWC and they still eat and grow like crazy!
I’ve had an accident a coupl of days ago where I left the light on for 48h. After giving them 12h of dark, my work schedule didn’t align with the grow schedule. But I have definitely seen this problem getting worse. From 1 plant to multiple. You can find on my profile another question from yesterday with another photo.
Again, to remind you, what insect could cause this?

Nutrient burn?The leaves on my two plants are starting to show signs of burning. Is this nutrient burn? I have no added nutrients yet but I am using Happy Frog soil. I’ve raised my lights from 24 to 28” in case it’s light burn. What are your thoughts and recommendations?Week 2

Why are there soon many brown spots all of a sudden in WK 7?I'm entering Wk 7 and the same lady is hurting again. She's been feeding heavy for last few weeks and doing great. So, I gave a light water/microbes dose w/can and Epson. Now I think its potassium or something else entirely... Brown spotting, yellow, crispy? Thoughts?5 years ago

Is the browning caused by nutrient burn or symptoms of something else? I had previously backed off, but want to know if I'm missing something. Most of the stems are red for leaves as well as petrioles. My runoff is around 900 each time @6.1. Only one plant of 2 has this.Week 4

Leaf damage and flower analysisAsking for thoughts on leaf damage. I think there may be nutrient shock so I will be reducing PPM to 800 to see if that helps. I am confused by other problems seen on a few leaves. I also want to ask if I am getting close to harvest (check flower pics) since this is an autoflower

What am I facing? Plant is getting worst everyday, and I can't find the reason why. Thought it was a calmag def, but now I don't really now.When I switched to flower, I started watching some rusty spots on the leaves of the gelato.
After doing some research, I thought I was facing a calmag deficiency, and starting adding some calmag.
Plant is getting worst, I flushed the roots and water between 5.8 and 6 as canna ask

Nutrient burn?I believe I overfertilized this week. I am using a four bucket DWS system with Reservoir bucket. This is the last week of my veg and I might’ve been heavy handed with the fertilizer. At one point my solution was 1844 ppm. I usually run itbetween 8 to 1200 ppm. I delutedd the solution in half. I didn’t have time to change it all because the lights are going out. Do you think this is nutrient burn? Thanks

Browning/Yellowing tipsBoth of my GSC's are suffering from browning/yellowing tips? will they recover? is this because of heat stress, nitrogen deficiency or over-watering? or something else?
The second plant seems to have the most browning/yellowing fan leaf tips and first plant had little to none.
