Hey GrowDoc, thanks for your fast reply. You think i got Ph-Troubles?
On the Bio Bizz Website it says that you don´t need to regular your PH with the Bio Bizz Product on Soil and you should not mix things like Hesi PH Minus and Bio Bizz together.
I don´t know if theres a organic PH Minus to buy or something.
It´s my frist time Organic growing, sry for the perhaps stupid questions.

Thanks alot Growdoc, you really helped me. I will get my hands on some Plagron Lemon Kick since it´s organic as well.
I read this quote somewhere: "Don't adjust the pH of your nutrients in biobizz, They are 100% organic, so contains no salts unlike synthetic netruents, adding Non organic pH adjusters will harm the soil. The soil will hold the pH accordingly."
So i was afraid to mix some ph regulator in, but now you showed me that there are also organic ph minus.
I will try it out and tell you what happened.

Why is it shit? I gotta say i have never had such a great growth on other soils like on the BB All Mix.
And i have some friends which grow really nice weed with Bio Bizz and Bio Tabs and soil.
But yeah it looks like in my environment there´s a problem with the nutrients.
Why and how did you find out that it is shit on soil?
Edit: BioBizz told me this:
We prefer you give water with Biobizz every time you water the plants. If you switch between just clear water one time and water with nutrients the second time, you’ll have every time different Ec/pH levels. Every time the plants need to adjust.
" BioBizz says if your ph is between 7.0 and 7.3 it's just perfect. Don't change anything! Feed it to the plants and the soil will buffer the rest. "
Our soil has a pH of 6,1-6,2. This is the perfect pH for using our liquid products. When you water the plants, the Biobizz products start to decompose, with the help of the micro-life in the soil, the organic material breaks down and the pH always stay naturally at 6,1-6,2. So if the water you give has a pH of for instance 7,0-7,3, the micro-life will ensure the pH in the soil will drop to the desired 6,1-6,2. This is why you never had problems, because you let nature do it’s work.

if the yellowing is mostly at the tops then yeah i would look into it being too intense.
initially i wanted to say mag def but overall looks of the plant in the pics looks like either too much light or too much food indicated by the scorching at the tips and the way the ends of some of the larger fan leaves are starting to claw slightly.
i assume you would have determined if it was overfeeding like i said or if you need to do whatever everyone else said. sorry i've been away. didn't read all the replies.
i use to work as a soil mixer/re-builder, everything from used soil to new soil. i used biobizz soil to bring down hot mixes or dilute topdressings.
Its not correct for me to say that bioizz is shit, its an ok product. I personally belive that there are better products out there.

Alright so i tried to check my PH with an GHE Ph Testkit, i know this drop tests are not really accurate. But i searched the web a little bit and many people say that the one from GHE is the most accurate from all the other drop tests.
The test told me my Ph is between 8.0 and 8.5 which is too high. Even if this tests are inaccurate of about 0.7-1.0 the ph would be either 7.0-7.3 or 9.0-9.3
Do you guys think that the Soil is able to buffer my high PH water down to under 7.0 for months?
If not then it really is a Ph-Problem and i need to drop it a little bit.
But let´s see how they react to the clear water now.

plant is in her 9th week of flowering and buds are airy and with almost no resin at all :/
under 400w and 50litre air pot .
soil is COCO and feeding was Lucas formula 8/16 M/B then 6/9 cuz i was trying to do something diferent hopping she would react , but that didnt help... heat and exhaust is functioning , got air condition in the room and dont really know that to do next.... should i feed just bloom ???

what happened when you dropped from 8/16 to 6/9? anything at all? when i was using locas i changed the ratio of mic to bl i lower the micro as we get further into flower making sure only minimal amounts of nitrogen are being supplied.

This is been dogging me for over a year – please help!
This is been dogging me for over a year – please help!
First post, though I've been lurking here for about 5 years. Several indoor and outdoor grows under my belt, some good, some bad, but always learning and having fun
I've been banging my head with this one for a while, but hopefully you guys can help me close in on the problem and find a solution.
Symptoms: Slow growth, red stems and dead spots on the leaves that often start as a bright yellow mark on an otherwise dark green leaf. Affected both veg and flower plants, upper and lower leaves. Some powdery mildew too, but it's spotty and not full-blown. (Been treating with neem oil every couple weeks).
Strains: Multiple (SD, HB, JH, CD4, WBF, BIR)
Soil: Sunshine #4 aggregate plus
Containers: 2 gallon (flower), 6" (veg)
Water: unfiltered tap (Hetch Hetchy reservoir)
Nutrients: Maxibloom 5-15-14 at 1000 ppm pH 6.0 (flower and veg)
pH pen: yellow one, etekhcity branded
Total room size: 4'x12'x8'
Flower area: 3'x3'x8'
Veg area: 2'x4'x5' tent (within flower room)
Lighting: 400 watt HPS (flower) 4x32 watt T8 (veg)
Temp/Humidity: 70F/45% currently (have seen humidity as high as 65%)
Intake air: filtered, 6", passive
Air circulation: 16" oscillating fan (flower) 6" clip fan (veg)
Extraction: 6" HO Can Fan with carbon filter to outdoors (flower) 6" booster fan to room (veg)
The leaves in the photo are taken from multiple plants, both flower and veg.
Checked my pH pen in a solution pegged at 7.0 and it read 8.0. So when I adjusted my nutrients to 6.0, in actuality it was probably closer to 5.0, which would seem to lockout phosphorus.
Would the low pH cause the symptoms I'm experiencing? The dead spots on the leaves?
Any advice would be much appreciated. Thanks for reading!

That sunshine mix has little calcium in it.
Spend the $50 on a soil analysis and see where you really are.
If you go to the slow nickel lounge, you will see the results from a number of growers that have learned to read a soil analysis and found that they were greatly lacking in Ca.
At that pH, throw some gypsum on and watch what happens.
When Ca is low, everything is low.

Thanks for the response slow nickel!
I've been treating the sunshine mix as if it were lacking all nutrients and feeding with Maxibloom at 1000 ppm every other watering (alternating with plain tap water). It's been a few months, so what was originally in the soil is probably flushed by now.
Looks like the Maxibloom contains 5% calcium. Do you think it would still be lacking given that feeding regimen?
Also, when you say to add gypsum, what should I be looking for? I do have a 50 lb. bage of hydrated lime on hand...would some quantity of that work?
Thanks again for the help!

Unless you are super acid pH in that medium, that lime won't do much other than spike your pH. Realize that the pH scale is exponential, not linear. You are guessing at your pH....
Any idea of what the pH and ppms of your water is?
Realize that a soil needs 10 to 12 times more Calcium than potassium.... check our your formula. And at a 1000 ppm of iron, that stuff scares the dickens out of me...
Your grow isn't worth $50-60 or so to send in an analysis and stop guessing?
Those red stems and slow growth sound like a P issue. Given your K is so much over your P, that could be a real issue.... Your fertilizer is really a 5-6.5-11.6 if you looked at P and K not P2O5 and K2O
So the ratio is really screwed up and what you are describing is really a P issue.
No photos?
Try and find a bag of gypsum, calcium sulfate. If you really are that acid, the lime might help if you can get it in... A bit of calcium nitrate might be faster and would raise your pH too...
FYI that image gallery hypertext doesn't work.

Thanks! If the plants don't turn around after adding the gypsum maybe I will look into the analysis. Just feel like all signs are pointing to a P deficiency due to my miscalibrated pH meter. Unfortunately, I don't have access to any other photos right now, but if the problem persists, I'll add more. Sorry about the link, I'm still trying to figure out how everything works here.
If your pH is really acid, you won't like the result with the gypsum.
Why not get a P source? Some mono ammonium phosphate maybe? You have anything with heavy P and little K? Even a foliar application would work.
A soil needs as much K as it does P. Your relationship in that fertilizer is backwards. That is the reason you are having a problem.
