Last photo , maybe magnesium. Tops are bleaching i see. Think its calcium if no spray as mentioned before. CalMag to the rescue ;)

What's going on with my clones? Do not have much information to add. VPD is not terribly off, DLI around 25.
What's going on with these clones? Not sure what it could be. They could possibly be rootbound. They should have been transplanted a few weeks ago but I did not have the space.

lower leaves yellowing in 3 days?
Over the past 3 days my 2nd plant lower leaves started to yellow. Both are fed the same amount and the same rates. I noticed the one that is yellowing the leaves are upwards and that is a good sign, but the lower leaves are yellowing too fast. I am unsure what could cause this.

Yellowing of leaves during flower
What is causing yellowing of the bottom/backside fan leaves during week 5 of flower? Should I worry about it spreading? Increased bloom nutrients to 3ml/l recently but could have started when feeding 2ml/l. Or is this just leaves yellowing as a part of flowering?

Mag Def?
Does the yellowing between the veins on these lower leaves look like a magnesium deficiency?

Yellowing leaves, some twisting, early in veg?
Could anyone help me diagnose this plant. Idk if it’s nitro defic., heat stress, or overwatering or all 3. Temps during the day have been getting up around 86-88 daytime and only down to maybe 74 at night in the tent. I try to let the top of the soil dry out when watering as well

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!

Deficiency?
Hi, I've encountered some deficiencies in my plant but I'm not sure whether it's Magnesium, Potassium or anything else. I'm using the BioBizz outdoor trypack (BioBloom+FishMix+TopMax) Currently 2ml/L each. Symptoms are shown in the lower leaves. Maybe CalMag? or Pk 13-14? pls lmk

Droopy leaves, weird spots.
Does anyone know what's wrong with that bottom left plant? Those spots appeared pretty soon after I cleaned those filters. I'm thinking that it's a stress caused by that cleanse, no chemicals or such were used, but some roots were torn in the process. Deficiency? Disease?
