Keepz what strength are you using? i cant run full strength i hit 2.0EC at second week of flower following schedule! I've been just kinda of playing it by ear trying to go around 1.7EC before additives becasue when i got to 2 EC shit started burning. i'm running the same line of nutes for the first time but i'm in a Ebb and Grow.
also where did ya get them ballasts? haven't seen them black boxes and wondering if they are special or were on special.
Peace fam,
Xceptional
I'm goin to explain my ghetto ass way of changing out my nutrient water every week. Where i live there is no municipal water, its well water from a spring fed lake i have property on. I filter this water because its better 2 be safe than sorry and H&G recommends it.
I'm guesstimating that the 12-site 13g bucket system holds about 150g, maybe less, on its own since none of the buckets are ever completely full.
As I remove the nutrient solution i replace it with well water until my EC is like .1 or .2 Then i ph 5.8 and flush for 8 hours. After the flush, i remove 100g from the system and replace with 100g of RO water. I turn off the air pump and just let the mag drive run as I introduce part A. Let recirculate for 30 min. and add part B. Then ph 5.8 and add all their additives. My EC hasn't gone above 1.5 except when i mixed a batch of the aggressive formula and i had to back off from that and it was cut with at least 30g of well water LOL.
The crazy shit about it is... After the system has been topped off with RO water during the week, the EC will drop to .5 by Wed!! So i know they're CRUSHING those nutes. i've yet to wake up where the ph of my nutrient solution is all of a sudden acidic and only observed exactly the opposite where its gradually climbed upward. I could see why Jack tops off with nutrient solution and i've yet 2 figure that one out. I just add some A then B with air pump off on wed. til EC hits 1.0 and add a few tsp of Maxicrop. Ride the ph til Sun. when i dump my rez again. -Keepz
P.S. ballasts are cheapo switchable mag ballasts i get for $86 with 2-year warranty (like u'll need it). And then i get the Horti Super HPS for $63, all system chord set $14, S to H adapter $4 add 10% shippin = 1k of vertical shenanigans!!! As long as u hav the electrical all figured out of course =]
