Outdoor Flowering Leaves Twisting And Pointing Up (Heat Stress?)

I've been dealing with borers the last couple days, and after a hard fought battle I came out on top. Now there's a new mystery to solve. :confused:

Location: Outdoor
Flowering: ~ Day 33
Growing Medium: Organic Soil (Peat, Perlite, EWC)
Nutrients: All water until flowering, nutrients supplied by soil. After the second week of flowering, I began using Botanicare: Hydroplex @ less then recommended ratio.
Container: Potted up from 16 oz. Jiffy - 1 Gall Nursery Pot - 7 Gallon Nursery Pot
Strains: Afghan Kush, Satori, Kiwi Skunk, Super Lemon Haze

Problem: I go out today to check on the babes and there are no more borers, YES!. Now I got a new problem, at least I think It's a problem. For the first 20 or so days, the buds have grown beautifully, full of trich's and thick as hell. Now, on the tops of the flowering parts (Buds), are these twisted and drastically upward pointing leaves? In the process the plant seems to be growing, thus making the buds extremely airy (see pics). I'm wondering if this is a normal process, and eventually the budding area will fill out. I took pictures of the calyx, you can see it's there, but it almost just looks like trich covered leaves. The last 3 days have been records in my area, reaching into the upper 90's, maybe that has something to do with it. It wasn't this hot most all summer. You can see where the buds are tight and compact, and almost look like their coming apart up top. Their not re-vegging are they? I thought it might be borer related, but the one plant didn't get touched, and it's still has the bud leaves doing that.

I've proceeded to water then with rain water and no additives to see how it goes. What is everyone opinion, help a fellow grower get some dense nuggets.

[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]

Good shit my dude. I'm thinking it's either 1. or 2. Maybe a combo of both. I don't know but it sucks it says they can't recover.

Does that stand to say it's pretty much one of those though. "[FONT=&quot]A misdiagnosis only serves to make matters worse by promoting further decline." Guess I gotta make that decision.

Would one assume the correct course of action would be to water without nutrients, and try to keep to soil cool during the heat of the day?

this answers my problems at least hahaha

click the link in my sig for my journal to see if u think i over ferted/watered since i watered them with a little bit of nutes when i transplanted into foxfarm when i know better cuz ocean forrest already has nutes in it :/

+rep for the both of yas!!

I would assume so. might try mulching the pots to help conserve water too. was the soil dry when you watered?
Thanks, my personal guardian angel. :lol:

I was going to post in the other thread & let you know the borers have been eliminated, I got a little side tracked with this most recent development. I've had a wide array of answers so far. From, It's nothing but standard growth, to heat stress, to Re-Vegging. I think I'm going to do what I said as my course of action and see how things go. Mulching the pots would probably be an awesome thing to do for my situation. I bet it would really help prevent the wicking away of the water since my growing medium promotes it.

Thanks bro

Super growing secrets 1 and 5

The number 1 rule is if shits going sideways Flush, flush and flush. So when you flush you need to have some nutrients in the water, at least 15% to 20%. WHY you ask

Without certain elements present other elements can't move so they get locked in you plant. For example

If all the nitrogen gets flushed out to soon you lock up the magnesium in the buds. Ever smoke weed that pops or crackles or sparks, people say it was not flushed right, well it's the magnesium left in the plant because they flushed with just water. Remember magnesium from science class in high school.

Hope this helps

Peace
