Are you flushing ? It's just the natural fade of the plant as it comes to the end of its cycle in flower. Nothing to worry about , it's just a lack of chlorophyll in the leaf as she fades out.

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!Leaves. Color - Yellow

Hey, anyone got any idea or clue what's going on?I thought it was a manganese or iron deficiency from an early watering with high pH.
Though I've fed/watered my other 2 plants pretty much the same stuff but she seems to be reacting really poorly.
She seems to be getting better slowly.. I think.
Thanks for taking the time. :)5y ago

Runoffs are significantly below inputs-Do I have a problem?Runoff continues to be a mystery. When watering I continue to get significantly less Ph and PPM (4.8 ph and 109 ppm) than my inputs (6.2 ph and 155 ppm) but the plant looks healthy. I have no idea what is going on or if its even a problem. Should I be worried and what can I do?Week 6

Leaf burnt edgesOne leaf has burnt edges and is a little different looking, than the other leaves. Is this some kind of nutrient burn? I am using a light mix soil, and have not fed the plant with additional nutrients, except for a little root stimulant (half of recommenced dosage).6y ago

Looking for clarification on the Flush time required for a RDWC grow? I have read this can be as little as 2 days of just plain water but should this also include CalMag if I am RO water? I assume the standard root rot treatment continues? i.e. OxyPlus, HydroGuard, Phytoff?Thanks6y ago
