Plagron Batmix Soil questions

[greenops]

I've always used Plagron's Grow Mix soil for the entire grow. They are lightly pre-fertilized for the first 3 weeks. But since I've noticed that hungry strains turn yellow early in this soil, I looked for alternatives so I bought the Plagron Bio Batmix.

Now I realized that the manual for Batmix says:
Do not fertilize the first 6 weeks.
And the pH of this soil is higher 6.5 - 7.5, as opposed to the Grow Mix pH 5.9-6.9.

I'm not sure if it works well to veg the seedlings for the first 4 weeks in the Grow Mix first and then to transplant the plants to a pot twice its size filled with Batmix? Will the plants benefit from a mix of two soils to somehow find a compromise?

Shortly after that final transplant I will switch to 12/12. Since I won't be able to use a lot of Bloom Nutes and Boosters due to the strong soil, won't the yield suffer?

ive had some of my best grows using plagron soil. i use royalty mix now called royal mix. dont use bat shit mix for veg its way too hot. i use royal mix for veg and my last repot i use either 50% bat shit mix 50% royal mix or light mix

Cool man, so if the final 11l pot they end up with contains like 50% grow mix and 50% batmix... that's ok?

I'm confused because I was researching on the subject and read somewhere that mixing soils can cause pH issues, or that plants can show deficiencies and overfeeding symptoms at the same time. Seems kinda weird to me, but I just wanna make sure.

I would cut the Batmix with some coir and EWC. Add some dolomite lime.

If you then add 2tsp per litre of blood, fish and bone you will be sweet for the cycle. By the time the bat poo gets used up the bfb will take over.

Water with rainwater and add molasses for a few waterings around day 40-50.

You can also supplement your soil with seaweed meal.

I'm 100% confident you'll have a great grow!

i grew twice (from seed) with batmix, results were good.

then i grew once (clones) with the royalty mix and it turned out to be too hot.

switched to the light mix for the next one - good results.

i cant add bfb, i gotta work with what i have now, thats a half sack of grow mix and a full bag of bat mix.

I would just like to know if I can mix those two bags together when i transplant the plants in their final pot?

You will be fine...but the plants will need food towards the end of their stretch. Shame you can't add the BFB. It's very cheap...

Best of luck
