Mephisto Genetics 4 Assed Monkey, RDWC, COBs and MegaCrop

[Boradan]

I had initially planned on doing an MBAP for this grow, but decided to go with the 4AM that I received as a Freebie.

Grow System:

1.2m x 1.2m x 2m Mars Hydro tent
Modified Aeros IV Master RDWC system
4 x 150W 3500k self-built COBs
RAM Humidifier
2 x 6" fans (one fixed, the other Oscillating)
4" Extractor with Carbon Filter
Oil Heater for temps if needed

Nutrients:

MEGACROP
Remo Velokelp as a Foliar Spray
Great White
Remo Magnifical if (when) needed
Atmai AtaClean will be added to help keep the lines clean
Plant Magic Bio-Wetter will also be added to increase water uptake and nutrient absorption

We have Liftoff!

All of the Rootit plugs are now in the netpots:

First Feed (70 Litres of Tap Water):

Megacrop: 31.75g (total)
Magnifical: 0.25ml/l
Silicon additive: 0.2ml/l
Great White: erm.... a shake...

pH: 5.9
ppm: 232
RH: 78%
Air Temp: 25.6C
Water Temp: 18.5C

DAY 4:
Stretching a touch too much, so I have lowered the light a few inches to slow that down a bit.

Sub'd up man.

I am using 1 gram of MC per liter. Twice as much as yours. How did you decide how much to use? This is a table I put together based on @slowandeasy testing with greenleaf products. I have done parts of a run in bloom phase using this schedule and its good. And just starting a new run and using the veg part of the schedule with no issues or nute burn.

That's a nice schedule. I will let you know how the Bud Explosion works with those levels. It is strong, so it is always good to start light at first to look for burn. I may try 4.0 MC and .75 BE for 1 gal and look for any burn. 4.5g and 1g is not where I would consider right, could be too strong for some plants. Reducing the MC in flower should reduce NPK a little, allowing for more BE.

That initial weight is from the MegaCrop feeding guide based on 70L.
As it is the first week, I am simply monitoring pH and EC and will increase/decrease based on the changes there.
Currently the pH and EC are stable (the EC is rising, but only VERY slightly by 10ppm so that is not really an issue), so the nutrient level is correct for these particular plants at this time.

Greenleaf has stated their schedule needs work bro. So others have been testing it out and came up with something that should be better. Just thought you might want to know that.

I have MC at 3.5g per gallon and BE at 1.5g during all of bloom. And I used that for some plants that were on AN at the start of flower and then switched to Greenleaf product. Actually the values I used at first were not good and I had some def. Once I switched to 3.5 and 1.5 they were OK.

I have some new plants on day 11 that have been on Greenleaf since day one using the latest schedule and all 5 of them seem good to me as far as nute strength goes. I just dropped them in to precharged autopots yesterday using @912GreenSkell instatransplant (non-transplant, just drop in seedlings in cut out solo cups in to pots) method. Seems to be off to a great start. Looked good this morning. I'll post some pictures later.
