Should I give my plants the fox farm tiger bloom with sings of preflowers since the 15th of dec ?
Im also still vegging under 18/6
Im also still vegging under 18/6

No, you don't have to feed them any certain type of fertilizer just because there may be preflowers. Any reason you're not using 24/0?

heat sress but mainly cost wise.

Stick with your vegging nute, i like to keep using veg nute every 3rd feeding or so when early in flowering though, the stretch phase uses alot of nitrogen.

Lotys of reasons not to do this, the main one is that roots grow in the dark cycle, so even though they may grow bigger, they will lack the power to grow buds as big as they could with 20/4 or 18/6.

Veg fertilizer till they start showing bud growth (1-3 weeks after 12/12 switch depending on the genes), and then start with a 1/4 or 1/2 mix and gradually build it up.

Thats not true. I'm not for using one or the other it depends on situation, but this just plain aint true. When you clone what light cycle do you root under? 24/0.........roots grow fine under 24/0.

Yes, they grow fine, but not at there best. I'm afraid this is scientfically proven, research it a bit and u'll see.
The whole point of hydro is to optomize the plants natural growing environment. Plants need the dark cycle as much as the light, they evolved with it.

Sure it is, show me your proof guy? this hasnt been proven at all......

Actually, plants do benefit from this rest period as much as me or you do. They actually stop respirating CO2 and take in O2 during this cycle, as well as putting a little more energy into root development. The dark cycle has just an important role in root development as moon cycles. Read the farmers almanac. Its not just for tomatoes anymore.

Indeed, which is also why you shouldn't vent too much or feed CO2 during the dark cycle.

indeed this is true. it is still ok to run 24/0 ive seem just as good of grown with both light cycles.

Most green plants are classified as either C3 or C4 which represents how carbon(C) is used during photosynthesis.
C4 plants temporarily store carbon dioxide(CO2) over the dark period to use for photosynthesis during the day. C4 plants slow down photosynthesis once the stored CO2 is used up and they need to gather it from the air. Which is why trees slow down photosynthesis in the afternoon even though the sun is still bright. This does NOT apply to cannabis.
C3 plants(cannabis/veggies) gather CO2 only during the light period when they are photosynthesizing. During the dark period these plants only use oxygen for their metabolic life processes. They don't uptake CO2, nor do they use it. As soon and as long as the light is on, C3 plants gather and use CO2 for photosynthesis.
C3 plants also have the ability to use higher concentrations of CO2 than what is found in the air. If the light is bright enough and the plants have sufficient nutes, their growth rate will accelerate from it(2000ppm vs. 400ppm of CO2), which increases yield. They can do this continuously, wihtout a dark period throughout the vegetative stage.
The dark reaction is a process of photosynthesis that takes place in both darkness and light. It uses ATP and NADPH molecules that hold energy absorbed from light to break apart CO2 into it's base components. Because it's called a dark reaction and can occur in the dark, some people(Jorge) have said darkness is needed for this to occur. This Is Not So.
Again people get anthropomorphic with their plant needs. People need rest, so plants must too. This is false as well. Light means growth. Scientifically. it's a personal choice If you want to save money or energy that's a personal choice too. Do what you need to do to make your growing scenario work.

I believe they do a little better with dark cycles...But the real reason I use one is cost to grow vs. results. They do a little better under 24/0? I'll save some money. And as far as clones. I don't know about you? But I run fluorescent lights, that cost far less to run than metal halide. And even when I did run cuttings I ran them 20/4. Another thought to this is that plants do more than one thing at a time. The truth is that the lights we use are really weak compared to the sun. That's the truth. Why else would we run longer light cycles? Anyhow it's a personal preference some guys do really well with it some don't. Good growing everybody!!! Just my two pennies.

24 hours of light throughout the vegging process will grow plenty of roots to support the beginning of flowering. From then on, the roots grow even faster because of the dark period and grown properly, will stay ahead of all bud growth. While yours and some other growing systems may need help with root growth, the slower growing roots of 24/0 is actually a benefit for many growers. It can allow for smaller pots for each plant, more plants and ultimately more to harvest. It's especially good for mothers and long-flowering strains that stay in the same pot a long time. The slower root growth and/or having a smaller root system going into flowering helps to prevent root binding. Since the more the soil dries out, the faster roots grow, with 24/0 the soil can also dry out further between waterings with the same root growth. The 24 hours of light also provides twice the energy for plant growth, allowing the plants to make use of more fertilizers before burning.
Even using 24/0, we've had good results pruning the root ball during transplanting into the flowering soil mix. It's just another way to decrease pot size. We have more room now and don't prune the roots anymore but when we did, the yield wasn't any different from the plants we didn't trim the roots of. So vegging in 24/0, our root systems are much more than adequate when 12/12 starts.

Thanks for the heads up man im waiting to get some extra cash and im going to make a veg. room out of a portable closet or computer armoure.

I gave it some epsom salt last night and so far cant tell the difference my only other guess is it needs more N. Or it could also use a flush its in hydro the fox farm chart calls for a flush for two days in week 7. Any suggestions I will try and get a pic of the leaf up. If it helps the veins are also green but the leaf is yellow and seem to be working its way up.

It could be too much or too little N. Over fertilzing causes the roots top go into shock and stop absorbing nutrients. If you're using soil, then its a safe bet that they are getting too much, so flush them slowly with the same amount of water as the size of the pot, let them drain well, and don't feed again until the soil is dry again.
