Cannabis leaf symtomp

I use biobizz too, should be fine. It´s recommended to add mykhorriza and the root juice is good too. But whats curious the whole plant turned yellow. Was it too hot? Was the watering ok? Greets :)

After a bit of "googling", it appears "Bio Grow" by Bio Bizz is more of a soil "tonic" rather than a complete nutrient. They do not give any information anywhere as to its NPK ratios and the fact it is made from sugar beet refuse suggests to me that it contains none or very, very little NPK and this would explain why your plant is so pale. Further, it is designed "to feed soil microbes" again indicating it is not a complete fertilizer, but to be used in conjunction with other substances, and Bio Bizz themselves suggest using this product with one of their own branded soil mixes as part of a "growing system". So, in other words, you need to buy some other nutrients for your plant to get it really growing. Bio Grow just isn't complete without the use of the recommended range of Bio Bizz soil mixes that makes it a balanced "system" for plant health. If you are after "bio" type products, either Bio-Vega by Bio Canna (excellent product - half strength is plenty!) or Flora Nova Grow one part by GHE (excellent too - again, half strength is plenty) are two products I can recommend highly. They are both complete nutrients, so no mixing with Part A/B/C and are true one bottle nutrients and both are quite concentrated, meaning they will last many grows/plants. They also have their counterparts, Bio Flores and Flora Nova Bloom one part, making growing simple. My nod goes to the Flora Nova Bloom one part over the Bio Flores - can't say why, it just seems to work a bit better. They are both worth every cent and produce luscious plants!! Good luck and happy growing! ,...... Organoman.

Since your still in Veg, it could be not enough Nitrogen and possible root bound
