Cal-mag issue that won't go awayI keep getting a cal-mag deficiency. I have been using 1ml per liter of water - 4ml roughly per gallon. It is only 1 plant, the same which has had the same cal-mag issue since early veg.
I include cal-mag every watering and nutrient feed day.

Deficiency on Fem. Girl Scout Cookies?I am watering sporadically and only every 2nd watering I add nutrients... haven't checked PH in a while but is usually around 6.5
The top leaves have no burnt tips - so am I (finally) having a nutrient deficiency?

Brown spots new leaves - floweringBrown spots on the canopy and leaves are less greener. I suspect it is Calcium deficiency caused by a acid Ph (my Ph meter was not calibrated). I have flushed it and fed it normally 5 days after the first signals. Is it really Calcium def or another thing I'm missing?Week 12

Emerging Issues - Week 9At the beginning of the week, I noticed the tips of the leaves drying out. Now, one out of the four plants has completely yellow leaves. Could it be due to the increased Biobizz Bloom dosage? For more information, please check my journal. Regards.

What is this!?Hello there. I have, as you can see a bit of an issue regarding my plant. What is this? As you might see, the lower leaves seems ok, and that concerns me even more. I have flushed her properly and then gave her adequate amounts of feeding. At first I thought it was lack of P.

Leaf tips are browningCiao tutti,
What is going on with these leaf tips?
It’s the third day of their Flush & It can’t be NutBurn, or the color of tips doesnt look like NutDef!
Is the light stress?
If this de-coloring continues, will it effect the buds & final yield?
Thanks

Deficiencies? Brown spots, yellowing and purple stemsWhat is this deficiency or maybe toxicity and whats the solution? She is fed with biobizz chart instructions but with every other watering. She is big so I'm guessing I should water with nutes every time? She showed this first week into flowering.

Plant HealthI have a few brown spots and slight yellowing on a couple of my 3 finger leaves and even some on a 5 finger (#2). It seems to be getting worse every day. I have done a lot of research to find out what it could be but am very confused. Any ideas? Pictures from 2 different days.
