Help needed Bio biz almix soil Tested ph run off 6.4 Humidity fine temp fine iv also flushed once

What nutrients are you feeding the plant and how often? Also, what is the PPM of the runoff?

Also in their Q&A: Question: After adding the nutes to the water, what to do?

Quote " 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. "

I did find this, they have a base 3 nutrients and the rest are stimulant and boosters.

If you would use all products at the same time you do not need to worry that much, since you are only using maximum to NPK products: Bio-grow or Fish-Mix and Bio-Bloom. All other products are stimulators that compliment the nutrients, improve assimilation, metabolism, chlorophyll production etc etc etc.

We try to give a divers menu to the plants. If you want to live healthy, you do not eat a hamburger with a hamburger and a hamburger for desert. You’d eat a hamburger, with a salad, some orange juice, a yogurt or cheese for desert and maybe a small digestive afterwards. This is the function of the stimulators: Root-juice, Bio-Heaven, Top-max, Alg-a-Mic and Acti-vera.

Try to see it like this: You use as a basis Bio-grow or Fish-Mix and Bio-Bloom. The stimulators are your tools to guide your plants into the direction you want to go, or enrich them. You make the menu for your plants, depending on the type of plants, their age, the moment in the cycle and of course the type of genetics.

Biobizz doesn't have much details online that I can find. If @Mr. Grow It isn't familiar with this line you may need to contact the manufacturer for feed/deficiency advice. What little info I can find the bloom looks like a nutrient booster, and the heaven 1-1-1 I think would be way to low especially in flower. I did find where it said when you flush to flush with ph'd nutrient mixed water. I don't want to give you bad information and have you burn your plants. Let's hope @Mr. Grow It has info on your nutrients.

Biobizz almix soil, its there second 2 feed so far bloom and topmax bio heaven, into about 10 days flower as the soil is an all mix and they been growing sweet till now, the others a growing fine still just this 1, 5 gallon pot

Trying to find info on bio biz medium, is that soil based or Coco? I keep seeing references to hydro, if it's Coco your ph needs to go down.

Looks like manganese deficiency. Could you do a ppm run test, what nutrients are you using and how much?
