Hard to say.. but a pH in of mid 5 is wayyy too low for soil. Get it up around 6.5 This was my issue with FF trio. Tiger bloom is great but it absolutely tanked my pH to problematic levels

Hello community, I need help. My plant kept getting yellow leaves. I responded with more fertilizer. That seemed to help for the time being. She is in the 5 WEEK flowering phase. The nights have been colder than usual for the past 6 days. Now 60% of the leaves drooping and yellow

Curled leaves and brown spots
Please help! My Acapulco Gold suddenly showed leaf symptoms today. Shouldnt be a lock out, I always water with drain and use lower doses than the BioBizz chart recommends. Used Molasses two days ago, could that be the cause? Its the only plant that shows this signs.

Is this nitrogen deficiency? Should I change the soil?
Is this nitrogen deficiency? I've been feeding them and using pH Down but nothing changes (pH 7.2). Should I replace the soil? They're in CannaTerra mixed with Promix. I've got some FoxFarm Ocean I could move them to.

Harvesting a struggling plant or just letting it fight
Can she be saved or just flush her and harvest what I can? She doesn't appear to be happy. Has some CBD genetics so the lack of trichomes don't worry me. Rest of my garden is fading as well. Flushed em last feeding and they didn't seem to like it.

Yellowing copper leaves late flower
Harvest is coming up soon and I have noticed some of my leaves mostly the bottom but some on top also have started to turn yellow with brown/copper spots. I believe it is cal mag deficiency, will this mess with my yield or quality of the bud?

I know it is normal for the leaves to yellow in the flowering stage but it is only 3 week and 5 or 6 leaves become yellow on the bottom should i use more nitrogen to prevent it or let it be ?

Drooping leaves
The leaves on the royal dwarf are drooping down a bit, I think this may be overwatering, anyone have any idea if this is correct?

Seedlings going yellow
Could yellowing of leaves on seedlings be from too much fertilizer ( liquid fish, compost,seaweed type.) I wouldn't suspect iron deficiency as it is new premium potting mix that they are planted in. I did feed with about half strength liquid feet about 5 days ago.
