what a deficiency is this?
BrieflyGrowinganswered grow question 3 years ago
Hi Bud! I used exactly the same BioBizz nuts and soil in my first auto grown with RQS seeds and had the exact same issue. Exactly the same spots on the leaves...
So I can say I'm 90% sure it is a Calmag issue. I solved it by adding CalMag from BioBizz to the feeding with their recommended dosage = issue solved.
My water is pretty soft, around 50/70ppm so almost no Cal or Mag there, so pretty much expected.
You are pretty early on the flowering stage so if you act now I don't think it will affect your yield. Good luck!

Looks like Cal/Mag to me
And some Cal/Mag maybe cut back on H2O

It does look like calcium to me.
should add in some CalMg, should not need to much as you are in soil.
Its also beneficial to let BioBizz nutrient mix sit up all mixed up for 12 hrs to left the PH drift then adjust if you need to.
It can go all the way down to 6.2 in soil and still have good results.
Good Luck!

Leaves color changing in flower!!!!what do you think ? deficiency? or is just normal for leaves to become like this after 7 weeks from seed of an autoflower?
max i fed was 400pm just once. I don't think thats overfertilization. Maybe ph lockout?

Tried everything - Red spots almost everywhere. Turn from red to orange/yellow. Fungus?Getting very frustrated with these speckles. Iv tried decreasing Cal Mend and B-52. Improving air flow. Cleaning the tent head to toe and the res. Iv tried using UC roots. Im really not sure what's going on and IDK what to try to fix it. Grow was going so well. This sucks.

are the rust colored spots that start during flowering a fungus? I sprayed with the sulfur and cleaned tent and it still happen is it from the temperatures being too low and humidity too high at night? Does it hurt growth and thickeningcof the buds? What does nute burn look likeWeek 9

Have a look at my leaves that have turned yellow and red. I've search online and can't seem to find a similar picture. Is this normal due to late flowering in some plants? Is this a nute problem? If I add the needed nutes, will this clear up? What's going on?Week 8

Leaves burningRepost with new pics
I was thinking we had a def in calcium ( see last question) and started to just treat with 6.5 ph water, cal-Mag plus 2.5ml/g everyother day.
Leaves are turning a shiny burnt orange color and drying out on the edges. What is going on and how to fix it?

Purplish colour on some buds and sugar leavesHi starting to get ready for a flush, I've brought the nutes down to 380ppm and will start flush when I get around 300ppm and flush for a week, I've noticed purple hue on some buds and sugar leaves on about 10 different bud sites, it's looks lovely but should I be worried?? TIA
