Is this a deficiency or light burnHi all my other plants are perfectly fine except for this one it has brown edges on the leaves and has been growing the slowest out of all my plants and I was just wondering how I could fix this? I checked the run off PPM yesterday and it was 1100 so I flushed it and now its 700

Upward Curling Brown Leaves/Nutrient Lock Out?I've got a serious issue. Started 3-4 days ago, right after adding nutrients and increasing light.
Leaves are curling upward and browning. Not crumbling yet but look like they will be soon.
Both new and old growth is being effected.
Maybe the Mineralized Phosphate was too much.

Rust spots on leaves, second grow and need some confirmation.I'm noticing rust spots on my leaves, which I suspect could be due to nutrient burn or lockout, given the PPM is unusually high for this stage of growth. To tackle this, I'm planning a simple flush with some Cal-Mag, keeping the pH at 6.5. Does this sound like the right approach?

Rust spotsMy lower leaves are showing rust spots along the veins. Appears to be a magnesium deficiency but I am feeding cal/mag. I also growing in ocean forest soil. I’m starting to think this is nutrient lockout? I’m feeding a low dose of nutes(250 ppm every few days) soil could be hot?

Ph issues part 2Hi guys! It has been a while after flushing, repotting into bigger pot with fresh medium and feeding her only with water. I bought Sensi cal mag extra and I need your advise if it can be used together with BioBizz nutrients, I could get only this brand in my local store

Será uma deficiência de cobre?Ola, sem ser a questão que já não consigo subir mais os leds e as plantas já estão a mostrar sinais de stress por causa da luz.
Agora apareceu me uma das plantas assim, com as pontas amarelas mas a ficar maior.
Fiz um flush para limpar, pois penso que seja nutrientes a mais.

Friends need your help! the leaves turn yellow at the seedling stage!Friends, help me figure it out!
First I will describe my conditions! - Tap water 110 ppm - LED QB288 Rspec 250 Watt light works at half the power! - Advanced Nutrients three-component Fertilizers Micro Grow Bloom
now I'll tell you how it was!
after they have sprouted! they were planted in the system! I made the solution on the recommendation of the fertilizer manufacturer! I added 1 ml/l of each component and it turned out 410 ppm! The second week I changed the solution completely and added 2 ml/l of each component, it turned out 600 ppm
the yellowness on the leaves appeared after the first week! I thought it was a magnesium or iron deficiency! and I changed the solution and added 2 ml / l of fertilizers! I keep the ph of the solution within 5.7-6.0
drip irrigation works constantly!
The temperature in the box is 23-25 C - humidity is 40-60%
Inside, there is a fan on top that turns 360 degrees to blow the plants!
