Just Be Careful Invi, On The 48 Hour Of Darkness Thing. No Offense Alex801, But Prolonged Periods Of Darkness Can Make Your Plant Turn Into A Hermi, But If They Are on Their Very Last Stage Of Flowering, I Would Not Worry About It To Much. As I have Not Read Your Entire Thread, Just Perused It, The Curling Leafs Are Definitely A Sign Of Too Much Nitrogen,But That Question Appears To Have Already Been Answered For You. Have You Thought About Growing Your Plants Out In Veg Stage Under Fluoros?? Less Heat, BY FAR, But Also Much Less Lumens. Because Your Plants Are Under So Much Heat, This Is Stressing The HELL Out Of Them, As I Am Sure You Already Know, And Someone Has Probably Schooled You On That As Well.
As I Am An Outdoor Grower, Except When I Start Them Indoors, For Two Weeks, Under Regular Shoplight Fluoros, I Know That Indoors, HEAT Is The BANE Of An Indoor Crop!!!
Outdoors Though, The More Heat, Water, Nutrients That You Have, Is All A Plus, Weird HUH!!! As far As Putting Them Under A 48 Hour All Dark Stretch, I Would Say This Is Not Necessary. The Resins Are Already There, And After You Harvest, When They Are Drying, You Will See All The Little Resin Glands Pop Forth As The Plant Dries, So Long As The Plant Is Not Some Mutant That Has Ruderalis Or Hemp In It. I Grew A Lemon Skunk Plant One Year From Jordan Of The Isle Seeds, Took Good Care Of Her All Year Long, But NO RESIN!!! I Waited All The Way Until October 31st Before Harvesting Her. Never A Bit Of Resin Did I Ever See, Or Get Off Of That Damn Plant!!! Then I Found Out That Jordan Of The Isles Seeds Uses Ruderalis In Most Of Their Strains To Bring The Harvest Time Down To An Acceptable Level, Only Problem Is, That Because Each Seed That You Make From A Pair Of Plants Has Different Genes Mixed In, And Unfortunately, This Particular Seed(LIKE DIFFERENT BROTHERS AND SISTERS HAVE DIFFERENT LOOKS AND HAIR COLOR),Got The Height And Girth From The Lemon Skunk, But Unfortunately It Received It's Lack Of THC, And Resin From The Ruderalis Side Of The Family Tree. It Sucked For Me, As It Was A Colossal Waste Of Time, Energy,Love And GOOD Garden Space, Needless To Say, I Never Again Ordered From Jordan Of The Isles Seeds!!! Thats One Sure Way To Lose A Customer, I Tell You True!!! Where Did You Purchase Your Seed invi, If I May So Bold To Ask? And Yes Your Exhaust Tubing, Does Kind Of Make Your Grow Space Look Like The Millennium Falcon(LOL)!!! I Hope The Money You Spent Getting Your Spaceship Ready Will Be Recouped On The Amount Of Medicine You Eventually Harvest. But From What I Have Seen In Your Pictures, I Do Not Believe So(NO SLIGHT INTENDED HERE invi),Just Speaking My Mind, And The Truth As The Way I Can See It. I Believe On Your Next Grow, Wait Until Fall, So That It Cools Down, And Veg And Flower When It Is NICE AND COOL Out Of Doors. That Way You Will Not Have To Worry About Your Plants Frying, Unless You Forget To Water.
Another Question I Have Invi, Is How Much And How Often You Water??? Plants Should Be Watered As Needed, Never Keep Them Moist, Just For The Sake Of Keeping Them Damp, Let Them Go Through Periods Of Wet And Dry, Not Too Dry Of Course, But If You Have A Green Thumb, It Should Be Apparent To You When To Water And Feed. A Plant Needs To Breathe. So When You Water, Soak Them Good, Feed Them If It Is Time, I Feed Once A Week, On A Rotating Schedule. First Time I Feed, A Week After I Have Put Them Into Their 4 Inch Containers(I START MY SEEDLINGS IN 4 INCH CONTAINERS), That Way, Until I Move Them Outside After 14-17 Days, I Usually Only Have To Water 3 Times, And Feed Them Twice, 5-7 Days After I Have First Planted And Watered Them, I Use Only Fox Farm Grow Big Grow At This Stage(ONE TBSP Per Gallon Of Water, And One Full Measured Cup Of Nutrients Per Each Plant Of The Grow Big, From The Gallon Of Premixed Nutrients), Then As The Plants Are Under 24 Hours Of Light And After The Fertilizing, Will Begin To ZOOM In Growth. By The End Of The 14th To 17th Day, They Will Be Ready To Move Outside. BTW, At This Stage Of Their Development, I Would ONLY Use BLACK GOLD Potting Soil For Them, As It Is Very Airy And Easy To Flush, Should By Accident You Over Fertilize. It Is The Black Gold That Comes In The Black And Orange Bags. Do Not Use Their Seedling Mix, Or Any Other Type Of Soil, BLACK GOLD IS ALL YOU NEED(I HAVE 20 YRS EXPERIENCE DOING IT This Way, And It Had Never Failed Me!!!
After At Least Two Or So Weeks, Take The Plants In The 4 Inch Containers And Move Them Outside, Then Transplant Them Into 3-5 Gallon Containers(I USE 3's), And Black Gold For This Transplant As Well. Now Let Your Plants Grow Into Their 3-5 Gallon Containers, Continuing To Fertilize With The Aforementioned Fox Farm Mixture(1 TBSP Per Gallon Of Water It May Seem A Little Strong, But I Promise YOU, It Will Not Hurt The Plants!!! Cannabis Is A High Nutrient Uptake Plant, And As Long As You Always Water Before Feeding, You Should Never Have Any Problems With Burning, Unless Of Course You Make A Ridiculously Strong Mixture Of Nutrients, Like 3 TBSP Per Gallon Of Water. After The Plants SEX, Which Can Take As Little Time As 2 Weeks, To As Long 3-4, Sometimes 5 Weeks. After They Have Sexed, Set Them Aside, If You Choose To Make Your Own Seeds,(As I Do, So I Always Have Good Seed Stock On Hand, Grab Your BEST MALES!!!) , Then Separate The Females From The Rest, And Pick Which Ones You Wish To Grow. How Close Are Your Lights To The Tops Of Your Plants??? You Should Place Your Plants As Close To The Lights As Is Possible, Without BURNING THEM OF COURSE!!! I Do Not Know How Large Of Containers You Use For Your Indoor Crop, But The Larger The Containers, The More Yield You Will Receive!!!
Perhaps 3 Gallon Containers Are As Big Of Containers That You Can Fit In Your Space(OR NOT???), Anyways, After I Have My Plants All Sexed, I Separate The Males I Choose To Keep For Seeding(MOVE THEM TO A VERY SHADY PART OF OUR GARDEN So That They Will Start To Bloom And Put Forth Pollen Sacks, That I Can Harvest, As They Get Ready, Label What Type Of Plant Pollen They Are, Store Them In A Marked Butter Dish, And Freeze Them Till I Need To Pollinate My Girls, So I Have Seeds For Next Year Or The Year Thereafter. Usually I Toss Out The Pollen After I Use It For Seeding My Ladies, As I'll Just Make More Pollen The Next Year. That Way I ALWAYS Have Fresh Seedstock Every Year. Although I Rarely EVER Use All Of My Seeds Each Year, But I Keep Them Locked Away In Black Film Rolls, Inside Of A Safe That Is Airtight,Fireproof And Rarely Ever Opened. I Have Seeds That I Have Had A Good 10 Years, And Because I Keep Them In A Climate Controlled Room And The Safe Of Course, The Vast Majority Still Sprout, Although As They AGE, They Do Not Sprout Right Away, It Usually Takes About 4-7 Days, And If They Do Not Sprout By Then, In The Shit Can They Go!!!
Sorry For Taking Over Your Thread invi, As I Am An Outside Grower, Much Of My Advice Is Perhaps Useless, But Hey, At Least I Tried!!! Oh Yeah, When I Move My Plants From The 3 Gallon Containers, I Then Change Their Soil To 3 Parts Ocean Forest Potting Soil, To 4 Parts Happy Frog, I Also Add My Special Amendment Called Super Fert(IT IS NOT SOMETHING YOU CAN GET FROM A STORE OR COMPANY THOUGH), An Older Man That Was A Life Long Friend To My Mentor(RIP), Makes It On His Farm In Chico, But He Will Not Divulge The Secret Ingredients, I Know It Has Chicken Shit In It,Blood Meal,Petrified Bat Guano,Earthworm Castings And Many Other Things, Oh Yeah Lime As Well, But As For The Rest, I Can Only Guess(BUT THE RATIOS OF THE MIXTURE IS WHERE THE REAL SECRET LIES!!!), I Hope Someday He Will Give Up His Recipe, But I Feel That May Be A Forlorn Hope. I Add 12 Pounds Of It To Each One Of My 100 Gallon Containers, When I Transplant Them From The 3's To The 100's. Anyways invi, I Have Rambled Enough, If There Is Anything You Think You Might Like To Ask, Please Do So, Oh Yeah, One More Thing, When I Move The Plants To 100 Gallon Containers, I Change The Nutrients To Once A Week, In 5 Gallon Containers, I Add Between 5-7 TBSP Of Grow Big,3 TBSP Of GRAPE SWEET And 3 TBSP Of Cal Mag. The Next Week I Fertilize With MAX-SEA 16-16-16 With 5-7 Heaping TBSP'S Full, And The Same Amount Of Both CAL-MAG And SWEET I Give Them, That I Do When Using The Grow Big. I Do Not Know If This Has Helped You At All??? But It Sure Helped Limber Up My Fingers For Typing!!!:
: Take Care, And See Ya Around(I HOPE). SINCERELY, JAMESTHEGREEN.
