Seedling Light-burn or Toxicity
MMSC16started grow question a month ago
Hi growers!
Is this Light Burn, or nutrient toxicity from nutrient dense soil?
2 Mars Hydro TS600 lights at 27" from seedling.
PH 6.3 misting soil - RH is 75-80%. - Temp is 77F
No light meter, so I estimate PPFD is in acceptable range despite using 2 lights in 2x2 tent.

You can use alternative a lightmeter app. hold your phone in the hight of your plant. It works not perfectly but better then nothing

Light is likely too strong. Seedlings don't require intense light.

Can't see anything wrong..........you are overthinking things.
This is exactly how cannabis seedlings start out.
Misting the soil is pointless, it does nothing.........water properly!

It just looks like it's starting life, sometimes you can get funny colours at this age. Download an app for your phone called photone. It uses your screen camera to measure the light.

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!

Leave's tips color turning yellowCiao a tutti, da 2 giorni ho notato che le punte delle foglie si stanno ingiallendo. Ho pensato di allontanare la luce dalle ragazze, nonostante stia usando una LED (marshydro ts1000). Sapreste dirmi cosa sbaglio? Dovrei agire anche sulla quantità di nutrienti?

Nutrient imbalance or healthy development?Are the colors of the leaves a sign of healthy development in the flowering stage, or a sign of nutrient deficiency/excess? After struggling a lot with the nutrition of this plant, I am not sure anymore whether I'm doing it right. Some of the leaves become yellow and fall off.
