Looks like too much nitrogen and a magnesium and calcium issue started.

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 patches on leaves, thought it was calcium deficiency symptoms.
Having problems with brown patches, (see last 3 pics week 10), a quick google and I went with adding more CalMag but it's got worse the further into flowering I go, the farthest behind plant has least, furthest ahead is worst, any ideas?, many thanks in advance :)

Brown spots, PH in run-off is in the high end (6.5~)
I see some brown spots on my leaves. I thought it was Calcium Deficiency caused by too low PH so I gave them PH 6.5~ with 30% run-off, and run-off shows at least the same PH so I think it is not too low PH, could it be caused by something else? Maybe too high PH or light-stress?

Nutrient burn or deficiency?
I’m seeing brown spots that resemble a calcium deficiency but I’m feeding them cal mag:s One of the tips on the new growth looks burnt so it looks like i may be feeding too much or immobile deficiency? I’m feeding about a 500 ppm of newts. Any help is greatly appreciated.

Should I harvest early? Light stress, leaves browned and dried out, buds are all amber pistils
So this plant has been suffering from light stress for the past two weeks or so. I have removed all the dry and brown leaves. The buds still seem fine-ish. Should I just give her the chop early and save what I can? She's been flowering for some 6 weeks.

Possible deficiency?
Am I correct in thinking this is calcium and manganese deficiency? Do I solve this with a little cal-mag? All spots are on new growth so its immobile i think, Cheers people, happy growing and stay green ✌️ 💚 👌

Brown spots with slight yellowing
Hello gromies. I'm seeing some slight yellowing and brown spots on my fan leaves. I've been bottom feeding so maybe it's a lock out issue with calmag. I flushed with tap to get some run off. Any suggestions?
