According to your log your pH is a bit high.. this can cause a lockout of iron which it looks like what its doing.. shoot between 6.0 and 6.5 if possible! Cheers and happy growing!

Yellowing leaves
I’ve had a cal/mag deficiency last week which was treated through the week with calmag and no new brown spots, however leaves are still yellowing. Is there anything I can do about this ?

What's up with the yellowing leaves? They seem to yellow from the outside inwards and the tips also seem burnt too. Is it nutrient burn? Excess or Deficiency? It's mostly on the bottom but its affecting some of the bigger leaves in the middle too, Watch the video for an overview!

Leave's tips color turning yellow
Hey everyone, for the past 2 days I've noticed that the tips of the leaves are turning yellow. I thought about moving the light away from the girls, even though I'm using an LED (marshydro ts1000). Can you tell me what I'm doing wrong? Should I also adjust the amount of nutrients?

Losing colors :'(
I watered only 2L of water without nutrients this week (pot 30 L) You can see it on the diary photos, the plans have lost their colors (yellow). I wanted to know what exactly it was due to, because I read on the net a lack of nitrogen but I would like the expert opinion Thanks !

I need help troubleshooting weak plants! I think the clover might be the culprit but what do I do?
Can anyone tell me what’s going on with these plants and what I can do? This is my first grow. I can already tell the seeds are growing slow because other seeds I planted in smaller pots are growing much faster. Any advice would be greatly appreciated!

I need advice on what to do with this plant. I flushed her a bit and I think nutrient burining is not showing on new growth, what ppm should i feed her?
I watered only last week and mesaured runoff ppm and ph. Water was 350 ppm and 6 ph and runooff was 700ppm and 6.7 ph. Before when i fed her with 850 ppm runoff was 1500 ppm. I would continue to water only but there was a lot of yellow and pale leaves so gave her light dosage.

burnt tips/yellowing
My GG4 Auto has burnt tips and some yellowing on leaves. Just came back from a week and a half trip and RH was 35% and plants were pretty under watered. Is this nute burn? or from underwatering

Week 2: One of the plants still doesn't look good + other beginner questions :)
Second week and one of the plants has weird spots + leaves curled. Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea. Also, when should I start feeding the plants? And how much water do I need at this point? 😥
