wow, you have individual parts for each nute it seems? Nice! total control over nute ratios and ppms.. love it.
The one pic looks liek you may have lollipopped or defoliated a little extra but certainly has enough canopy to finish. could also be the angle of the picture (top-down) exaggerating it.
less is more when removing leaves. They power all growth, so you want as much as you can without causing high local RH levels that might encourage microbial growth. ATP (energy for putting biological building blocks together - in our bodies too!) is mobile although a local leaf will provide more to local area on plant than one far away obviously.
Irrigation since you mentioned it... always water entire pot and you want 10% or more in soilless grow. This runoff is 'waste' water.. don't let them set in it. You can toss this water outside in a garden where the potential imbalances and concentration will be mitigated easily. Or, toss it down a drain.
EC is best way to measure this stuff, cause hanna, and 2 other companies use different conversion factors to "ppm or TDS". So, if i quote ppms and we have 2 different brand meters, it's impossible to communicate clearly for obvious reasons. So, if i mention ppm it's calculated from the labels which will be the same no matter who calculates them. Any meter reading on other hand is better to use EC or CF which is consistent around the world.
While you lok to have already dialed it in, a nutrient calculator is useful in a soilless or hydro grow, since we control 100% of what theplant receives. It really helps to track this stuff as you'll find clear-cut min/max levels that are very translateable between grows, though not 100% due to some genetic differences... but far less than most ppl perceive.
i regularly run 6-7 strains that are very happy with my mix. I don't need 5 reservoirs with 5 different concentrations. That's a sign of an imbalanced, esoteric mix.
Anyway, manic botanix has a nutrient ppm calcualter.. simply type in % off guaranteed analysis labels of products and tabulate it. If you know the math, you can easily make a re-usable spreadsheet. I have one around somewhere but it does not account for specific gravity, if that is needed for your products (my stuff is dry). W/v% or w/w% is key factor there.. labels should mention this distinction. believe it's the w/v% that needs SG? the manic botanix online thing does account for it.
