Need some help

Hey whats up everyone,

This is my first grow, and I had a couple of questions. But first let me tell you what I have for growing. I have 5 total lights putting out 11,000 lumens on 310wats. I used MiracleGro Moisture Control soil in 3 8in Clay pots. I have a Temp/hygro meter stays anywhere from 70F when lights off to 85F when they are on. I have a cool mist humdifer which gets it to about 55% humidity. Iwater them with 200ml of boiled water every other day. I also spray them twice a day. No nutes yet. I have a fan for circulation. Thats all i can think of for now.

Ok now for my questions.
On my plants the first set of 1 finger leafs are kinda discolored on the tips and they seem to be wavy

Here are some pics





Ok i was also wondering when I should start with some nutes. The soil i got says it feeds for 3 months but I dont know if i believe that and what kind of nutes or ferts should I get.

Do I have enough lights if not how many CFL's do I need. The reason im using CFL's is they are cheaper and are more efficent. Im using the best ones GE offers I believe 2700 lumens for 42 watts i have 2 of those
here is a link 47452 - Features & Photos - GE Home Lighting Products
I also have one of their Daylight CFL's which is 1600 lumens for 26 watts and i have 2 GE reveal bulbs which combined is 2520 lumens at 200 watts

Well I think thats it for now. Here are some pics of my best plant




Thanks for any help guys

Looks good. You are going to want a lot more lumens for flowering though. One other thing, you pulling 310w of power for 11,000 lumens.. Ouch!

you need way no lumen for veg growth some where near 40k lumens and for flowering some where near 50k lumenspeace cali-high

Lighting

Light is needed by a plant for using nutrients and manufacturing food. It has a great influence on chlorophyll production, growth rate, leaf size, and flower and seed production. Light will be one of the most important aspects of your grow operation. For the purposes of growing marijuana, there are two basic types of lights: fluorescent's and high intensity discharge (HID), including MV (mercury vapor), MH (metal halide), and HPS (high pressure sodium).
HID vs. Fluorescent

The main difference is that fluorescent's create light by passing electricity through a gas vapor under low pressure and HID creates light by passing electricity through a gas vapor under high pressure. HID lights are much brighter and while initially more expensive, are more cost efficient to operate and will grow a much nicer crop. Therefore, they are the light of choice for most indoor growers.
Fluorescent

Fluorescents come in a wide variety of shapes and sizes. There are compacts, twist bulbs and circle bulbs. They all work the same way. They have a starter and ballast which help provide a steady and regulated amount of electricity to the light. Before HID lights were available indoor growers used fluorescent lights. While fluorescents can be used for an entire grow from seedling to harvest, it is generally not advised to use them in this way. To grow effectively with fluorescent's, think small. These lights are better suited for starting seedlings, rooting clones and small plants, maintaining moms for cloning purposes, and providing sidelight for the undergrowth. These situations do not require a high intensity of light to run their course. The light emitted by fluorescents is gentler and more diffuse, it doesn't release a lot of heat, and doesn't make the plant work as hard. For this reason they can be kept closer to the plant. One or two inches is sufficient, but this also means that the lights must be adjusted almost daily to accommodate growth which can be troublesome.
High Intensity Discharge

There are basically three types of HID lights. Mercury vapor (MV), metal halide (MH), and high pressure sodium (HPS). These lights also require a starter and a ballast.
Mercury Vapor

Mercury vapor is the type of lights that were used for streetlights many years ago. Not very good for growing because it doesn't provide enough of the right kind of light spectrum. While they do provide a littleof the blue spectrum, MV also produces too much heat to get very close to a plant, and are very inefficient to operate.
Metal Halide

The metal halide is a very good source of the white/blue spectrum of light that is ideal for vegetative growth. Many growers use MH during the vegetative phase. MH is bright and cost efficient to operate, but not as efficient as HPS lights. Most commonly used sizes are 400 watt and 1,000 watt. Works best when used in combination with HPS lights.
High Pressure Sodium

The best light available today for growing marijuana. High pressure sodium lights are very bright and very efficient. This light has a red/orange spectrum that is ideal for the flowering phase. With enough of these kind of lights you too can grow those centerfold buds. HPS comes in a wide variety of wattages from 70 watts up to 1,000 watts.
Lighting Forumlas

To correctly determine the best lighting for your space there are several things that you have to know. At this point, a couple of definitions are in order. The amount of light emitted by one candle that falls on one square foot of surface one foot away is called a lumen (lm). The amount of electricity flowing through a wire is measured in watts. Watt (W) hours measure the amount of watts used in one hour. A kilowatt/hour (kWh) is 1,000 watt/hours (Wh).
Lumens Per Square Foot

To determine how many lumens per square foot you have, find out the square footage of your space by multiplying the width and depth. Divide the lumens available by your square footage. This will give you lumens per square foot. For example, say your space is 3 feet deep by 4 feet wide, for a total of 12 square feet. The total lumens available from your light(s) is 45,000 lumens, which means you have 3,750 lumens per square foot.
How Much Light Do I Need?

Technology has advanced so much in the last 15 years that we are constantly refining the process and updating what we know works best for growing. Current theory holds that the minimum amount of lighting needed to sustain growth is around 2,000 lumens per square foot. Mid range is around 5,000 lumens per square foot. Optimal is 7,000 to 7,500 or higher lumens per square foot.
Can I Have Too Much Light?

The basic answer is no. According to the law of diminishing returns, you could theoretically reach a point when your plants just couldn't absorb any more light, but it would be impossible to have that many lights in your space. Heat from the lights would become a problem long before you ever reached that point. So use as many lights as you want, just control the heat.
Experimentation is the only sure method to determine the best solution for each plant. If plants are not receiving enough light, they begin to grow tall and spindly as if stretching for the light and foliage becomes pale green. Or, if they need to be moved closer to the light, or given a longer light exposure period. Too much light may lead to bleaching of leaves and flowers, browning and shriveling. Leaves would become overly compact and curl under at the edges.

Well it would be alot lower like 110w but 2 of my bulbs are just regular 100 watt reveals. Im gonna add 2 more of the daylight ones and 1 more of the 2700 lumen. SO that would be a total of 12900 lumens at 155 Watts. How many lumens do i need for 3 plants

wow i got like 3 plants with a 400w mh/hps light50,000 lumens thats means my plants are geting 5-7,000 lumen per sg ft my plants are gonna yeild great!theyre so big!45 tall and im only 2 weeks into flowering i started flowering when they were 39in tallpeace. cali-high

Don't waste your money on cfl's. Just buy a HPS. High Tech Garden Supply has an awesome 400w hps setup, with a blue spec enhanced hps bulb, and a reflector hood, this light can work from start to finish, it costs 119.95..

Well the only problem is i dont have 200 bucks to throw down on a light system like that. Those HPS arent cheap.

Oh im not gonna complain dude. This is my first grow i understand that i dont have enough lights but I will. If they die they die then i just start over with enough lights next time. I was wondering about nutes or ferts when should i add them and what kind.

damn it, that is not 2700lumes per bulb you have there, that is the temperature of the lights, that is 2700K! and i was kicking my brain to figure out how someone can end up with 11.000 lumens for 310W input:D with all those cfl's you got yourself there you will be in the 40k lumens range and fine for veg:)
but you may want to move those lights down, right to the tips of the plants;)
for flowering you have to bulk up a bit for sure if you want a decent smoke in the end, look for some used hps sys on ebay;)

What kind of BS is this? Are you trying to say that his cfl's put out 129 lumens per watt? 40,000 lumens / 310watts = 129lumens per watt. Trust me 310w of cfl's would NOT be in the 40,000 lumen range!

Yea that has some pretty good info thanks.
Still one of my plants insist on being all crappy. Now on one of the leaves the sides is all discolored and kinda crispy i guess. Oh well i still have 2 good ones haha.

Hey whats up its another day so im gonna post some pics.

My Temp/hygro meter


My sick plant



And my 2 good ones


This one comes in second place


Well everything seems to be going ok nothing to bad has happened to them. So I guess will see what happens.
