Hey MegaFlowaMasta,
What nutes and additives do you use and when do you use them - if I may ask?
I am getting those yellow leaves in my buds and I read it can be from not enough sugar. I added some more nectar to see if this helps. How much silica do you use and how often? I am not getting any yellow bottom leaves so I do not think I need any more N yet. She is getting 0-10-10 bloom and 0-0-1 FruitNfusion nectar. I also gave here some Sensi Grow B for some micros and minerals to se if this works better than the CalMag or JungleJuice Micro. I will add some silica tomorrow (it always raises my pH).
ppm is 540
pH is 5.1 (read sativas like 5.1 to 5.
Cheers,
Mo
