Can I get everyone's opinions please

Ok, so I hear that by doing the same grow routines routines, yields can be different from city to city. I'm basically getting half the yield for flowers size that looks the same so I'm trying to figure out why. I've compared the differences and talked to a few people so I narrowed down to these factors:

a) hard water/soft water (some cities have close to 0 and others may go up and past 1000. Maybe some of imprutities in the water can cancel out some nutrients?)
b) humidity/relative humidity (is 30 something % too low? how much does it actually affect the density?)
c) ph levels (I know it is important but how important is it really? would a 7.5 ph water solution actually make the buds that much less dense?)

So, by keeping everything else the same, what do you think is the most important factor and 2nd and 3rd on affecting the bud density. Share some experiences with me please..:bigjoint:

all 3 of them and how they r applied and or compensated for in my oppinion... it all comes down to experience and how to do what and when with what u got... TLC, patients, experience and knowing ur plants and what they like are big factors too.. if i had to pick 1 of the 3 ide say humidity and temp

I think your right about things being different in seperate cities but at the same time you need to compensate for those things. I you think you have hard or soft water test it and find out. The tests are rather inexpensive when you take into account what you are saving from growing your own.

As far as relative humidity goes, whats ideal varies depending on what stage of growth your in but 30% will work regardless and I dont think it will affect bud density.

However I see a ph problem as huge especially if your talking somewhere in the mid 7's. The ideal ph for pot is very near 6.5 and even though that sounds like such a small difference your actually talking about a 1000% increase in ph.

I always ph so cant say for sure that not doing so will create lighter buds but it seems very likely the problem to me. If I was to pick one of the 3 potential causes you suggested I would say ph.

Putting the 3 in order like you asked for I would say most likely ph followed by relative humidity then the hard or soft water.

Either way this is a very simple fix. Go out and pickup a ph tester and a water hardness tester and do the legwork. Start ph'ing your water and increase your humidity to the ideal level depending on your plants specific growth stage.:leaf:

Different people in different places have to adjust for different factors to different degrees. If they do that they don't end up with different results.

Well the most important factor you didnt even mention LIGHT !!! Id say out of your choices PH would be the most critical.

PH is SUPER important. A jump from five to six isn't like a jump of 1 point on a volume dial. It works exponentially so 1 WHOLE point is a HUGE diffference. ALSO, certain nutes are not taken in by the plant at a high PH, or a too low one for that matter. Nitrogen is taken in at a lower PH (high 5's), and Potassium is better received at 6-6.5. Another thing I have noticed is the PH on my reservoir when I mix a batch automatically dips down to high 5's, then slowly raises naturally over time. I think this natural change in PH is what allows ALL the nutes to be slowly taken in by the plants. By the time I check the PH of the soil the next day, its back up to 6.5, which is perfect. ALSO, you can be giving your plant all the NUTES it needs, but if your water is 'hard' then it may aleady have some contaminants that are keeping your nutes from even being held in the water (water can only hold SO MUCH nutrients). Also, the range of problems can easily fall into ALL THREE of the problems you mentioned. A humidity of around 40-50 should be good. Might want a second opinion on this. Hope it helps!

I'm using a 1000w HPS and I don't think that's the problem because I've always used the same light before.

I've started to control the pH by using pH down so I'll have to see how that works in the end. Meanwhile do you guys think it's THAT necessary to use reverse osmosis? because it is somewhat an expensive investment. Do you think that close to 300ppm of contaminants will really affect density that much and lock out some of the nutrients?
