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!

Brown spots on leavesWhat seems to be the problem with my plant? The old leaves get brown spots whereas the newer ones have yellow edges. Is it a pH issue?
Is there a fix to this?
I grow in soil and the plant is 4-5 weeks old.
Thanks for help!

Salvageable? Or pull?Well boys I done fucked up. Got a major K deficiency (since fed them). Didn't want to save them with liquid nutes as I'm trying organics. Assuming they live (I think the Bubba may have bounced back?) should I try to get a harvest or should I just pull them now? 1 week into flip.

Yellow leaves on nearing end auto.So we are nearing the end. Now there seems to be a lot of conflicting information out there on yellowing of leaves at this time. Some say it’s fine some say it could be hungry or lock. The bud still seem to be growing so not to sure what to do. I stopped feeding about 5 days ago.

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).
