Does this look like a magnesium deficiency? Getting some yellowing around the edges of some lower fan leaves.

This is burning from feeding too much or too often,.....or both.
Acapulco Gold being a sativa requires much less feeding, especially nitrogen, than your typical indica or hybrid.
Cutting your feeding in half should stop this from getting too much worse.

I had the same with my Lemon Haze 3 years ago. It was a ph problem (too high) which caused lockout troubles. The nutrients were in the soil but because of the ph value the roots weren't able to take them up. U are growing in hydroponic and i have no experience with that but a "flush" or change in water for hydro to the lower the ph would be my guess. After that a slow build up for nutrients and it will be fine.

Передозировка или свет?Подскажите правильно ли я идентифицировал передозировку удобрениями. Не думал, что органические удобрения могут так навредить быстро растению. Света даю им 550м/моль/см2. Но вот решил дать полторы дозы удобрений, так как заметил легкое осветление листы в середине куста.Week 8

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 “Grow #2” 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

Can anyone help identify this tox/deficiency?Week 6 I noticed that all the new growth has burnt tips I assumed this was a bit of a nitrogen toxicity problem since the leaves were all a nice dark green, no pale leaves were popping up. Also held back on feeds for a few weeks. Other forums said it’s normal but want to be sure.

Autoflower, deficiency or light stress? End of week 8.Good time of the day. Having following problems with my autoflower (see pictures) which is at the end of week 8. Plant had some light stress before, could that be a consequence of that? Or could that be nutrient deficiency? Looking forward to hearing from you guys!
