In most cases, this is a calmag issue. Either she's not getting enough or the pH is off so she can't take it in. Either way, easy fix! Looks great!!

If it starts from the bottom up it’s a calcium deficiency, if it starts from the top she needs more water! ( from my experience of course) hope this helps friend & happy growing!✌️🏼🌱

How dark is too dark?Are these looking too green? I’m not seeing any N-tox clawing but they are pretty dark, growth is pretty vigorous and steady though so I don’t know. They are in a pretty rich organic medium.

Anyone have any ideas what this orange/brown mark could be? She’s in RQS easy boost and only been getting ph 6 water. I changed her pot yesterday, possibly something to do with that? Maybe different ph in new medium? Only one affected so far out of 3 plants. Thanks!

Found something weird on my new leaves. Need an expert's opinion Found something weird on my leaves. I need an expert's opinion and insight. I don't know if it's natural to occur on newly developing leaves or if it's an issue that needs to be addressed. I'm thinking it might be natural but it seems weird to me.

V-Shaped 1st pair of leafes /White Widow Auto Hi i'm currently in my second 'experiment' to grow some auto's. The white widow shows 5 days after germination a v-shaped form of their first pair of leafes. The 2 Royal Jack's are slightly at the same path so i moved my GoLeaf X1 LED (150W) at 60cm distance.

Should I be removing sick leaves?When running into issues with yellowing and necrosis, is it better to leave the affected fan leaves of to take them off? Worried removing so many might have hurt me more than leaving them and trying to just fix the issue.

Schützt sie sich?These drooping leaves... what causes this symptom? I haven't written a diary about it (online) yet, but the plant has had damage to the taproot since it was a seedling. I also haven't been managing the RH well. It was at 45% for the last 2 days. Before that, it was okay.

Sagging leaves I have (2) 9 day old purple punch auto seedlings. They both have sagging leaves and were fine yesterday when I watered them. I think it’s because I have them in 2” peat pots inside solo cups. They get plenty of natural sun. They weren’t watered for 3 days before that.
