What kind of deficiency or issue are we having here? The other two are not showing signs like this although they are all fed/watered the same.

My plant has mass nutrient burn on most of the leaves, I've flushed the roots. Is there anything else that can be done to help recovery or is it to late in flower. Also should I remove all the effected leaves or will they still convert energy for the plant? Thanks

Well I added 280 ppm nutes and she showed signs of burn and the leaves dropped. I lowered the ppm to 200. Is that good enough? It's a very small amount of brown around the edges but I dont want it to get bad.

Nute burn?I have one plant that's browning and tips are starting to point up. I'm thinking this is due to ffof soil being too hot for this one the other 2 dont seem to have problems, though another slowed down and is getting a little twisted. Anything I should do besides continuing ph h20?

Beginning of week 8. Deficiency? Nute lockout? Normal for this stage of its life?Beginning of week 8 and her leaves are showing more spots and discoloration everyday. Is this normal for an Auto in the late stages of flower? Or do I need to feed more? Maybe a flush? This strain says she takes about 10 weeks start 2 finish.

Magnesium Deficiency ? How can I fix it ?got a little deficiency (maybe burned? but I think not). I'm pretty sure it's magnesium's deficiency, it happens after a flushing. I added 2 times the last 2 weeks a little bit of CalMag (BioBizz, but ive bought it 2 years ago, maybe it doesn't work well idk).

What can be the causing of the leaf curl upwards beside the obvious? like heatstress, waterdrops or maybe roots? seems also unlikely to me she has the same feedings as the strawberry. my other plants are fine. more info in the text. Thanks in advance

Nutrient burn or under watering?several leaves getting yellow at the tips. have not made any major changes to the environment in over 2 weeks. Water ph is 6.3. I am leaning towards under watering since the bigger of the 2 seems more affected. How would a more experienced grower proceed?

Hojas con manchas amarillas y puntas quemadasNote estas manchas amarillas en las hojas de mi og kush auto, esta en sus últimas semanas de floración, sustrato coco y perlita, que creen que sea? Y que debería hacer? Por lo que leí, se debe a deficiencia de magnesio y que es común en las últimas semanas, pero no estoy seguro🤔
