You sound like your in a pretty good place. The ec your feeding is a little high if your early bud. Older lower leaves will turn yellow and die. If the entire plant starts yellowing early, and your runoff ph and ec are good then there wanting a little more food. Early flower I run 1.2 ec in a week if I see yellowing happening I up my feed to 1.6 and run at that amount through mid flower, maybe 1.7 if they need that much. Late flower back to 1.2. Cheers

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!

Week Three slight leaf discolorationIn week three I'm seeing some slight discoloration. Not sure if it is something I should be concerned with. Using COCO, Worm Castings, ReCharge. Watering daily to keep the amendements active. Maybe I'm watering too much? Love to hear your thoughts. Thank you and happy growing.

Seedling leaf color is very light green.I'm wondering if there is any reason to be concerned with the lighter color leaves of one of my plants? They are significantly more "lime green" than the other two. he one in question is the bottom one in the picture attached. It is clear how much darker in color others are.

Leaves turning yellow from the bottom upMy older plants leaves are turning yellow from the bottom up. Its probably a nitrogen deficiency I think, I read that its common for plants in late flower but this one just shot its first pistils. What would be the smartest thing to do to combat this? Thx

Magnesium nutrient lock out, triggered by too much potassium ?@Burmese
Thank you so much for your help. 🙏😊 I think it was a magnesium nutrient lock out, triggered by too much potassium. I sprayed some water with Epsom salt on the leaves and it looks like it is getting better. 👍😉Week 4
