watering pro-mix

heya
Im growing 6 plants in 5 gallon buckets of Pro-Mix HP. 4 white berry and 2 sensi star, the white berry are a joy to grow, so vigourus. i cant wait to smoke the sensi star. I overwatered 'em early in life but they're recovering.
I need an effective watering strategy as watering (5.8-6.2ph) 'em 'till run off and waitin' till the buckets are light leads to me overwatering. I understand that peat holds an amount of water thats unavailable and the excess water is available to the roots.
And can someone till me why i cant water more frequently with less water? just gotta make sure its evenly moist. The only reason to water till runoff seems to be to prevent toxic salt buildup but this also limits the amount of O2 to the roots.

*widow maker, videoman, uncle ben especialy ur posts have been invalauble. much love, thnx guys.

Water your plants according to their size. If they're 2 feet tall in 5 gallon buckets, I'd give them about 1/2 gallon of water. You don't want to water until you see runoff unless your roots have reached and are covering the very bottom of your pot. Otherwise you'll just have a wet, heavy peat mix at the bottom of your pot that will rot your roots.

thanks buddy.

Do you have holes in the bucket? If not than drill 1/4 holes 1 1/2 inches up from the very bottom 4 of them.

The other ways are to lift them up, if light than water.

Get a cheap wall-mart moisture meter.

Be careful watering pro-mix, water will take the path of least resistance in pro-mix, it will not distribute evenly unless poured in very slow and around the pail.

To see what I mean put some in a tall glass and pour in half the height of the pro-mix in water and watch what happens, eye opening eh!

Water frozen up there yet? Choppers flying over looking for the out door, read they got 1200 6 footers near Cornwall.

Peace

haha naw i live near vancouver, moved a few years ago from norcal. Summer is just winding so it's an awesome time to start my first grow .
yeah got the side slots and holes on the bottom i learned to water it slow, takes a lot of patience. water wait 20min, water wait 20min. i think i got it down now. i bought a moisture meter but prefer to use my finger.
off-topic but one of the sensi star is showing rust spots on a few leaves. im guessing either ph or nute burn but im feeding every watering but at very low ec like 400-500ppm @.5

Here is a nice little guide I poached from somewhere

[FONT=&quot]Solving Marijuana Plan Leaf Curl/Cupping Problems[/FONT]
[FONT=&quot]Plenty of first time and experienced marijuana growers will suffer at some point in their cannabis growing career marijuana plants that begin to show leaf damage.[/FONT]
[FONT=&quot]Often they write emails or post on forums.[/FONT]
[FONT=&quot]“Help, my leaves are cupping and the leaf edges are turning brown!”[/FONT]
[FONT=&quot]or[/FONT]
[FONT=&quot]“My plant's leaf tips are curling down and turning black ....what's wrong?”[/FONT]
[FONT=&quot]Unless another marijuana grower inspects the damage a true assessment might not be possible. It's hard to tell "exactly" what the culprit is. Unfortunately the “solution” the marijuana grower chooses many times is not the right one.[/FONT]
[FONT=&quot]A misdiagnosis only serves to make matters worse by promoting further decline.[/FONT]
[FONT=&quot]The ultimate and correct solution is in the hands of the marijuana grower.[/FONT]
[FONT=&quot]Here are some common problems when marijuana leaves are curling.[/FONT]

1. [FONT=&quot]Too much marijuana fertilizer[/FONT][FONT=&quot]
   The most common cause of marijuana leaf cupping aka leaf margin rolling, leaf margin burn, and leaf tip curl/burn is overzealous use of marijuana plant food. In relationship to factors such as marijuana plant vigor and rate of growth. Leaf burn is often the very first sign of too much marijuana fertilizer.
   A hard, crispy feel to the marijuana leaf frequently occurs as well, as opposed to a soft and cool feel of a happy pot leaf. Back off on the amount and/or frequency of using marijuana fertilizer. Too much marijuana fertilizer can also burn the roots, especially the sensitive root tips, which then creates another set of problems. Note - as soil dries, the concentration of the remaining salts rises further exacerbating the problem. [/FONT]
2. [FONT=&quot]High Heat[/FONT][FONT=&quot]
   The marijuana plant is losing water via it’s leaves faster than what can be replaced by the root system. The marijuana leaf responds by leaf margin cupping or rolling up or down (most times up) in order to conserve moisture. A good example is reflected by the appearance of broad-bladed turf grass on a hot summer day, high noon, with low soil moisture levels - the leaf blade will roll upward/inward with the grass taking on a dull, greyish-green appearance. Upon sunrise when moisture levels have returned to normal, the leaf blade will be flat. Lower the heat in the marijuana grow-op and concentrate on developing a large robust root system. An efficient and effective root system will go a long way to prevent heat induced pot leaf dessication or marijuana leaf margin curling. One short episode of high heat is enough to permanently disable or destroy leaf tissue and cause a general decline in the leaves affected, which often occurs to leaves found at the top of the cannabis plant. The damaged pot leaf (usually) does not fully recover, no matter what you do. Bummer in the summer. One can only look to new growth for indications that the problem has been corrected.[/FONT]
3. [FONT=&quot]Too much light[/FONT][FONT=&quot]
   Yes, it’s true, you can give your marijuana plant too much light. Cannabis does not receive full sun from sunrise to sunset in its natural state. It is shaded or given reduced light levels because of adjacent plant material, cloudy conditions, rain, dust, twilight periods in the morning and late afternoon, and light intensity changes caused by a change in the seasons. Too much light mainly serves to bleach out and destroy chlorophyll as opposed to causing marijuana leaf cupping, but it often goes hand-in-hand with high heat for indoor marijuana growers. Turn down the time when the lights on in your marijuana grow room. If you're using a 24 hr cycle, turn it down to 20 hrs. Those on 18 - 6 marijuana growth cycle can turn their lights down two or three hours. Too much light can have many adverse effects on marijuana plants. Concentrate on developing/maintaining an efficient and robust root system.[/FONT]
4. [FONT=&quot]Over Watering[/FONT][FONT=&quot]
   For marijuana growers using soil, this practice only serves to weaken the root system by depriving the roots of proper gas exchange. The marijuana plants roots are not getting enough oxygen which creates an anerobic condition inducing root rot and root decline with the end result showing up as leaf stress, stunted growth, and in severe cases, death. Over watering creates a perfect environment for damp-off disease, at, or below the soil line. Many times marijuana growers believe their cannabis plant is not getting enough marijuana fertilizers (which it can't under such adverse conditions), so they add more marijuana fertilizers. Making the problem worst. Not better. Often problem 1 and 4 go together. Too much marijuana fertilizer combined with too much water. Creating plenty of marijuana plant problems.[/FONT]
5. [FONT=&quot]Not Enough Water[/FONT][FONT=&quot]
   Not only is the marijuana plant now stressed due to a low supply of adequate moisture, but carbohydrate production has been greatly compromised (screwed up). Step up the watering frequency, and if need be, organic marijuana growers may need to water from the bottom up until moisture levels reach a norm throughout the medium. One of the best methods in determining whether a marijuana plant requires watering is lifting the pots. The pots should be light to lift before a water session. After watering the marijuana plants lift the pots to get an understanding how heavy they've become fully watered. If the pot feels light to the lift - it’s time to water. Don’t wait until the soil pulls away from the side of the pot before watering. And of course, leach, once in a while to get rid of excess salts. These are the five most common problems marijuana growers encounter when growing cannabis. Correcting the problems early will save the marijuana plants, but may reduce overall yield. With practice and experience these problems are easily overcome which will then enable the marijuana grower to produce fantastic marijuana plants. With heavy yields.[/FONT]

yep uncle bens work, packed with info

I water mine until it runs off.

I'm in the middle of my first indoor grow right now with pro mix hp. Really happy! I water my girls 1 gallon everyday they are in 5 gallon bags. But my plant are mature enough to drink that. You have to always read your pots.

I'm curious because I'm running the exact same soil & buckets and the same amount of water ( 1gal ) but I only need to water every 2 or 3 days.
