My Green Gelatos have had a good Productive week all 3 growing identical at the moment . Good healthy growth with good coloring i have topped all 3 this week and will look to top again very soon. I am still expecting good things from these seeds. PH a little high at around 7, however i have some PH- arriving soon that should take care of this, Overall no complaints this week.
I am using a PH- from Dutch Pro. i haven't used a PH manipulator before and it has no usage guidelines on the bottle. I have used it approx 10ml to a Ltr mixing it in a separate container to where i add my nutes. Does this sound correct?
I compared with Dutchpro and Canna pH down. Dutchpro shows "Concentrated – 30% Phosphoric Acid". CANNA shows "Corrosive elements, 59% phosphoric acid" and recomends "Add pH adjuster in very small doses (5ml) to the nutrient tank, checking the value of the pH level until desired pH level is achieved (6.2)".

Using 10 ml / l is reasonable in my opinion. But, Please add 1ml/l (or less) and check pH, and do it again till pH reaches the good range of pH. After you know how much pH down is needed to decrease 0.1pH, adding more than 1ml/l. I did also adding pH down 5ml/l first and adding pH up to adjust the pH value. It increased also EC and made me mad😨.
@Cannibalgardens, Yes looking to switch them all end of week 8 however The harvests will be separate as the Queens will take a week or 2 longer than say the Gelatos. I like to grow a variety of strains as i never know what mood i fancy.
@UncleIsko, Hi i start with Bio Bizz All Mix for the first 4 weeks, This gives the Plants 4 weeks of slow feeding nutes. After this i change to the Bio Bizz light mix which has no added nutes, i prefer to have more control over what they are receiving from here on out. The soil is always of top quality and i believe it makes a huge difference. What about yourself?
Looks great! 7ph in soil is fine but 6.8 is optimal lowest being 6.3. Dont forget to let it slide back up near 7 once its ph downed to absorb all the nutes
Happy growing
