Magnesium deficiency?
Dr_Nowzaradan
started grow question 5y ago
Could it be magnesium deficiency or something else? I'm already using biobizz cal-mag with the suggested dose. Tx

I don't think it's magnesium problem. Also not a calcium problem. Is it a lower leaf and has your pH been on point.

Just had a look at your diary. Have you got plenty of drainage because you plant looks a little over watered. Make sure you get run off when u water.

Deficiency or overload? Any help appreciated
3 plants in question here. Minor burning on one of them? The other 2 younger ones have the bigger fan leafs turning slightly yellow. Some weird scarring noted too. Using dry amendments (earth dust, dolomitic lime). Soil, haze, 6.8 PH of filtered water.

2 Yellowing Fan Leaves
I have 2 large fan leaves from the main cola turning yellow and 1 almost looks crisp or burnt on the edges. It is only 2 of the leaves and by my reckoning, they are 2 of the oldest leaves on the plant. From research, it could be the bump in nutes or water issue. Any ideas?

Looking droopy/yellow due to light burn?
Looking like light burn (most intense from the top) and maybe overwatering? I am trying Nectar for the Gods #4 soil for the first time, and I just put it in a grow bag and put the clones in it. Unsure if I was supposed to prep somehow beforehand.

A bunch of different leaf symptoms appeared over just a few hours, can you spot the issue in my detailed diaries and solve the mystery?
Everything was well, until over just a few hours they developed all kinds of symptoms. I have 2 diaries here for the grow, the 2 called βGrow #2β and I am very detailed about what has been done day to day. So please have a look and see if you know what might be happening

Potassium deficiency?
Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?
