What is your growing medium? If you’re growing in soil I highly doubt it’s a cal/mag issue as there is plenty of cal/mag for a grow in most quality soils, more likely you’re Experiencing pH fluctuations in your medium.
Yellow leaves are continuing to appear on my ladyes, 8 week today.. I try to change the ph of solution but it didn't work... They're continuing flowering but I'm afraid for them
The way your lower leaves are yellowing from the bottom (from week 4/5 veg) you look like you are just experiencing hungry ladies. The yellow is to even to be ph related. If you are in soil and have active microbes your ph will always be around 7 no matter what. I see you fed bloom and no grow nutrients your last week of veg. Just add a little extra grow on top of the bloom next water and she should start to bounce back for you. Happy Growing!!
Hi mate, it is hard to see properly as the pictures don't show much detail but from what I see it just looks like a lack of nitrogen which can be normal at this stage. Maybe give her a little N boost or leave her as she is and she will be fine. Good luck and happy growing
Tuve y tengo el mismo problema con las fluctuaciones en el ph. Cómo tienes pensado hacer para corregirlo? Regando con un ph más ácido? Cuál es el ph de tu sustrato?
@Vps420, perfecto. Voy a seguirte para ver los resultados. Yo ayer regué con un ph de 5.8 para bajar el ph del sustrato que estaba en 7.2. gracias y que tengas buen grow!
@JuanHaze_Arg, I watered yesterday with water and bio bizz - (acid) I have to wait a few days to see the result and I can tell you everything .. But I measured the soil with a bad instrument and the result is between 7 and 8, the water I normally use it is between 6.5 and 7.5 but yesterday I added acidifier and it went down.. Wait few days for the result
@Vps420, first you need to know where you are, in terms of pH, collect some run off water after a watering and test that, that will tell you whether you need pH up or down.
