How long do you think you have until harvest? Are the buds still growing(fattening up) and looking good?

Buds are still going strong, I'm guessing around 4 weeks left. First 2 are of ww, third is Californian blue, and last was my failed ww quadline

With the MC it is recommended to use the weigh option, such as grams. If you have access to a digital scale start at 5g/gal.
That puts you at the flower week 1 stage for feeding. The next feed bump it up to 5.5g. 1tsp = 6g so not quite a tsp. The MC has big white balls in it so it's easier to weigh the product. It will last up to two weeks stored but needs to be agitated before use.
 
If you have to use the 500ppm scale then read what they say about it so you are familiar.....

*EC is additive, so you measure your base water EC then add in the suggested amount.
For example: Base water EC .2, suggested dosage is 1.1, then final level will be 1.1 + .2 = 1.3


EC/PPM conversion for different meter types

1 ms/cm (EC 1.0 or CF 10) = 500 ppm
European 1 ms/cm (EC 1.0 or CF 10) = 640 ppm
Australian 1 ms/cm (EC 1.0 or CF 10) = 700 ppm

1 US Teaspoon (4.9ml) = 6 grams MEGA CROP

Thanks again mauga..i've been enjoying catching up in your journals. Cant wait to get there..however many years it takes
 
For your small plants that may be fine if you are talking ppm on the 500 scale. The bigger plant in flower will be looking for more than that. The 300 they refer to is seedlings and small plants.
I'm assuming you have seen their feed calculator?
 
Most of my autos haven't got taller than 2ft
I start my autos around 200-400 hundred ppm .

My tap water is around 140-170 ppm.


I think I cruised through veg around 450 ppm total usually .
