Is this your Blue Dream auto? She beefed up since last week! Look like she is hungry. I don't know much about what soil base you use neither a Biobizz but from feeding chart she could use some this chart is for photos, autos are much more faster growing but on the other and you don't want to end up with to much N in soil once she starts to bloom. So I would believe you are week -1 but I would consider starting the bio bloom next watering as this looks from here like a possible K deficiency.

It May be Mg but before everything.
Which are the leaves yellowing? Older or younger ones?
Than try to contro the pH of the soil.
If is it 6.5-7 try to use coffe residues to make it more acid.

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

Blattprobleme bei Pflanze (Wahrscheinlicher Kalziummangel?)Ich habe 2 Pflanzen in Zelt und eine der Pflanze zeigt ziemliche Mängel. Viele Blätter sind mittlerweile gelb mit braunen Flecken. Die andere Pflanze hat diese Mängel aber nicht, beide wurden gleich gegossen, etc. Ich habe vor ein paar Tagen DolomitKalk und Worm Casting benutzt.7mo ago

Yellowing leavesHi Growmies, im in week 7 of my flowering cycle, my leaves have started yellowing between the veins before turning brown and dying from the tip inwards. Is this a calcium deficiency? Or is it natural dying from the end of flowering cycle or something else? Please advise thanks ✌️Week 16
