24-8-16 sounds like Miracle Grow All purpose. Use care, as it's real concentrated. I believe I was adding 1/2 teaspoon per gallon, once a week, (when I used to use it) but is not acceptable for flowering. You'll need a mellow bloom fert low in nitrogen. No additional nutes though, till the time release nutes wears-out of the soil.
When you order your ph pen, perhaps you could order some quality nutrients too. Usually best to stick with veg and bloom ferts from the same maker. Prevents imbalances and makes life easier.
Rusty Trichome Reviewed by Rusty Trichome on . Problem Im currently having a problem with my first indoor grow under cfl, I am currently feeding them rain water with a couple of drops of BabyBio to it, I always make sure the soil is nice and moist. It seems the outa parts of the leaves are curling up and turning brown and also a wierd shiny effect with spots is turning out on some of the leaves. Included pictures. Any help would be great? :( Rating: 5
