anyone????? my concern is that by the 6th the heat will reduce the life of the bulb, not sure if I'm right or wrong???

Hey guys, Just wondering how many 1000 watt hps's is acceptable to vent together? I can buy whatever size fan is acceptable, just wondering if 6 in a row is ok. Qualified responses only please. Thanks.

You can tell pretty quickly whats going on. I am upping my ppm's every feeding so when the lower leaves begin to yellow its obvious its calcium and magnesium. I must say though, I was not always aware of this and didn't supplement a few times and suffered dearly with massive amounts of dead...

I'm not sure if I would want to go with the dynagro because it DOES have calcium. This may cause a lockout if you apply it before it is needed. Is my thinking correct? I guess it depends how quickly the dolomite lime breaks down and makes those micro nutrients available. Maybe you could use...

I typically see a magnesium deficiency at around week 4 or 5 of flowering no matter what fertilizer I use. Thats when I start to supplement with a cal-mag formula and it basically stops. I was just curious as to why they wouldn't add it in the base fertilizer, but I get it now. If they did, a...

To be honest I haven't read the whole site. I just looked at the label and noticed it was absent. Either way I have a cal-mag supplement I can use if there ends up being a deficiency.

I'm not sure where you live but General Hydroponics is not cheap where I live (Canada). I'm not really overly concerned about price as long as it works. My last grow I used sensi bloom a and b with big bud and overdrive. To be honest, I used to use 10-30-20 in flower and I had better results...

Ok thanks for the clarification. I use promix, which I believe has no nutrients at all. I add dolomite lime as a ph buffer and to add some magnesium and calcium. I'm guessing that when I see deficiencies they will most likely be calcium and magnesium and I should apply accordingly.

Hey all, I have been researching fertilizers for a few days and reading every bit of information I can get my hands on. I have read quite a few of uncle bens posts and one of his recommendations is jacks classic all purpose and bloom formula. After reading the label I noticed that it does not...

Thanks for the replies they have been very helpful. I guess some experimentation is in order. I will compare some prices regarding dyna gro. Thanks again

Very nice pic, and I see what your saying. I will definitely take a look at that thread. I don't believe I locked out magnesium because it started low on the plant, and I immediately started to add a cal-mag supplement and it did not progress up the plant. I am also aware of lockout...

These are the opinions I was looking for. Regarding the secondary nutrients, I find that around week 4 I start to develop a magnesium deficiency, at which point I begin to add a cal-mag supplement. I know that during the flowering period, the plants begin to use quite a bit of magnesium. My...

Point taken. I am using sensi bloom a and b as my base nutrients. As I understand it, in terms of n-p-k, during the early part of flower, applying the p-k at a ratio of 0-1-2 is optimal. The numbers then get switched later in flower, to 0-2-1. This is in addition to your base flowering...

Hey all, Looking to start an opinion thread regarding bloom booster combinations. Last time I used big bud and overdrive. The results were ok but I'm looking to experiment a little, so just wanted to get some opinions on products that other people have used. I also kind of hate the price of...

He says to let them get 24" in veg, would you top them once or something to get a bushier plant? Then lollipop any stuff along the bottom that doesn't look like its going to produce?? Sometimes you just get that one main cola if you don't top them. What are other people's opinion on this??

I hear ya. Hopefully if I fix the humidity issue everything will fall into place. I'm hoping that the increased transpiration rate will result in more nutrient uptake and hopefully more dry weight. I just feel like I worked really hard on it, and to get half of what my goal was is a real...

I did have a little bit of bud mold here and there but not really a huge problem. I was wondering if this could be the reason for the low yield. I feel like I did everything right aside from this. I worked on them everyday, fertilized regularly with runoff, staked them up, etc... and still...

Hey Guys, Well my last crop I switched fertilizer to sensi bloom, big bud and overdrive and was very optimistic. My plants looked really good the whole way through. In the end I got only 1.1 pounds off of a 1000 watt hps. I did sog style in promix over a 5x5 area in 3 gallon pots. I didn't...

Hey guys, I have the growers bible and it states that humidity during flowering should be kept between 40-60% and day and night time temperatures should have a differential of 20 Fahrenheit. How important are both of these. I have a tough time with keeping my humidity down and I haven't been...

Fair enough if your results are what you say they are. But I have cloned with Jump Start and without and the difference is night and day. First, I don't get any wilting at all. Second, roughly 10 days in I have roots and not just a few, its to the point where the entire peat plug is covered...
