She is wanting cal mag and potassium. Is ph staying in range at 6.1, 6.2 range? Flowering npk ratio is 1-2-3
JerkFlowersanswered grow question 4y ago
Purple is caused by magnesium deficiency. Also 500 ppm is low for this current stage, feed more NPK nutes + calmag. Lights are also kinda close, unless if your lights recommend 13 inches at this stage of the game. Also you should add some Pure Blend Pro Grow if you're set on Botanicare. Plant still needs a little more N and veg grow nutes from fertilizer at this stage of the game before going to full bloom nutes. Basically start with grow nutes, then lower it and more bloom nutes (you are here), full bloom nutes.

Looks like she is hungry. I would increase the pure blend pro bloom dose to 5.28ml/l
Are you topping up with straight water or with the same nutrient mixture?

Seems like Potash Deficiency. But could be due to pH.
Also light burn could be an option.

Necesito experto! Double cookies auto BSFI had excess N at the beginning of flowering, I did a root wash and continued applying fertilizers regularly, today it looks like this. A lot of green smell but not from flowering, leaves with necrosis, I'm in the final stage of flowering and it's still vegetating with leaves in good condition!

I think I have nut issues?OK here's today's update, 3/9/22. They are all doing great, they're all standing proud now! I think they needed to dry out a little, more light and needed the extra nuts. What do any of you guys think could've caused these symptoms that my girls are/have shown?

Leaves continue to get yellow and fall off. Plant dying, bud looks okay.Still having issues with my plant. Leaves are getting more and more yellow and 2 have fallen off. Pretty far from harvest still for the leaves to be getting this yellow. Temps in tent are 18-22 c with leds 200w act wattage. Overwatered once but I doubt it would cause this. Ideas?6y ago

Yellowing lower fan leaves, a few red stems; N/Mg deficiency or normal low leaf die-off?Is this a Mg or N deficiency or are these leaves naturally dying off? Showing on only one of two plants so far. Appears only on lowest fan leaves. F20, 7L pots BioBizz AllMix and nutes (1mL/L Grow and 2mL/L Bloom). Temp/RH are good. Can't measure pH. Local soft tap water 7-8pH.
