PK 13/14 help?

It depends on the flowering time length of the strain you're growing. For 8 week strains I add pk 13/14 between weeks 4-6. Introduce low strength, then hit nearly full strength, then barely any. Something like that. I find this works better than just hitting them hard in week 5. For sativas and longer flowering strains just add pk for another week or so.

these are older pics and there now 3 weeks into flowering so thanks matey

try to learn from your plants a lil...it will help whne its time to feed

plants usualy tell you when their hungry...if its 3 weeks i bet they want some P/K

Those are some really nice plants The potassium leave can be high (20%) from the beginning of the flowering stage and finish at (40%) at the end of the fructification stage. I separate week 1,2,3 & 4 for the flowering and week 5,6,7 & 8 for the fructification. This is because the plant is going to need less phosphorus at week 4 or the beginning of the fructification stage. Always make sure that your nutrient solution concentration level does not go over 800 ppm. Check out my grow book right below for more details!

great advice yall thanks happy smoking !
