Is this cal mag deficiency?

MaxiBloom is a stand alone bloom feed. Use that alone without the florabloom. Florabloom is meant to be used in conjunction with floramicro, and floragrow.. all at different ratios thru out the entire grow.

Everyone mixes these 2gether. ITS A TRIO.

interessante... ho notato che nelle tue coltivazioni come in questa utilizzi solo un componente ,del tripac ,alla volta flora bloom andrebbe usato con flora micro e flora gro tutti insieme usandone solo uno si va incontro a varie carenze magari lo fai volutamente ma se non reintegri quello che manca avrai questi problemi...

After looking what you giving them and your purple/pink stems, you are coming up short gen on feed. Drop either 1 of your blooms and just focus on 1. I'm nearly sure 1 of them are part of a 2 part kit anyways. (Grow Comes with it to give throughout entire grow) Overall she looks like she has shortage of NP.. and when making up your cal,mag once you're batting around the 250-300ppm mark. It shouldn't be an Issue. But, yes, they're some cal spots the dose you are giving seems very low. Is it hitting 250ppm when you feed. As that's what you go by. Not by ml/l when applying the right amount of EC. Good growing

You have a Sulphur deficiency Before adding supplements to a plant's root zone, check the pH level of both the soil and/or the water solution (especially hydroponics) for plants. If the pH is high then it can be helpful to buy and carefully use a sulfuric acid-based fertilizer to both re-introduce sulfur, as well as bring down pH levels. If pH is within a normal growing range (5.5 to 7.0) then using Epsom salts would be a good source of sulfur for watering/hydroponics. In soil-based grows or outdoor grows the use of gypsum is good for sulfur introduction, but you may also use sulfate-based fertilizers such as ammonium sulfate or calcium sulfate, among others. If you have access, manure could be a great organic option as well. And if you like you can add a bit of calmag which in turn will add in uptake of other nutrients as well...
