2) Growing indoor or outdoors: INDOOR
3) Watering schedule: EVERY OTHER DAY, REMOVE EXCESS WATER
4) Growing Medium: ORGANIC POTTING SOIL
5) What stage of growth: 19 DAYS OF FLOWERING

OTHER:
-FEMALE, NO SIGNS OF A HERM.. FOR NOW
-I USED A TEASPOON PER GALLON OF A 0-10-10 SOLUTION, ONCE EVERY 10 DAYS
-THE END RESULT CAUSED HALF OF MY PLANT TO HAVE CURLED LEAVES AND BURNT TIPS. CURRENTLY STOPPED AND SWITCHED TO REGULAR TAP WATER
-LIGHTS: 3 COOL WHITE BUBS AND 3 WARM WHITE BULBS STRUNG ON LAMP (SEE PIC)

*** PLEASE REMEMBER THAT IM NOT A PROFESSIONAL, THIS IS A 'BAG SEED PRACTICE PLANT' TO SEE IF TIME WOULD ALLOW ME TO TAKE CARE OF A BEAUTIFUL PLANT. I GREW PREVIOUSLY UNDER THE SAME CONDITIONS AND THE HARVEST WAS GOOD, BUT NOT BOUTIFUL.. WHICH IS ALRIGHT W/ ME..

ONCE I HONED SOME SKILLS I WILL INVEST IN BETTER EQUIPMENT AND SEEDS. TIPS AND ADVICE IS GREATLY APPRECIATED.

Im having Similar Issues with my plants. A few burnt spots or black blotches...don't know what it could be. I think I sprayed them and the 400 W HPS was to close causing the burns, yikes.

Growing indoor with 2 x 21W cfls
Was Watering: 2 or 3 times depending on the moisture and weight of the medium
Growing on Coco
I am on 36th day vegetating

It happened after change my nutrient for organic, so now I am giving the old nutrient with more nitrogen and spraying buble water in the morning, but I am in doubt about heat problem.

6 Gals started from seed about 3 to 4 weeks old still in veg, started in an aero unit with an EC of 0.70 (using GH nute) and PH of 6.2
Just moved them to a DWC 3 days ago
600 watt HPS air cooled
GH nutes with EC 0.80
PH trying to keep at 6.0
temp from 68 to 74 f
waiting for a timer for the hydro pump , 1 min on 4 off, until then on all the time.
nute burn maybe??

pimp setup bro. and yes yellowing is normal towards the end but looks like your prob is a little more complex than that the tips brownig could b on overdose.

my girls are indoors under 150w hps
watered every morning ( no im not over watering) soil an i'm still in veg i think it might be nitro overload what do you think? i want to start 12 12 as soon as i find out to correct the problem. much thanks to anyone who can help!!

i have grown many times with hydro reservoir system which i am still useing. its indoor it waters one hr out of four.six plants are under a 400 mh and a 600 hps on a light mover. the medium is rockwool. now for the problem i have three trainwreck and three durban poison. the tw showed the problem first all the lower leaves were curling under and falling,while the uppers thrived and did just fine but not gaining alot of mass but not too bad. then about three weeks into fl i noticed that all the lower buds on the nodes would drop all their hairs and then almost dry up by looks. this is spreading to all my plants and devouring them pretty rapidly. i tried useind some hydrogen peroxide it helped but not alot. i cut a plant a little premie to look at the roots they are brownish. my friend is having the same prob along with 2 of his friends. is this a virus? or root rot? i question bad genetics also. any help would be appreciated

so i have these 2 plants that have been growing for about 2 weeks now, and just yesterday this odd coloring appeared on 2 of the same leaves, and is spreading to others. idk what it could b from.. i have them under a 6500k cfl, water every few days with air circulation. light is about 3 inches above atm.. its just getting worse and worse every hour. ima first timer so cut me sum slakk

I have always smoked, but since money has gotten tight and alot of my suppliers are getting caught I'm began growing my own. My seeds are from bag weed. I planted 8, 6 have popped up. They are in miracle potting soil, but it wasnt fresh. I put it in a container and it sat in a barn for about 4 months, so im hoping the soil isnt as "hot". I havent really timed it, but i say my plants are on week 3. I water them with filtered water. I get the cup of water and let it sit overnight to clean out all impurities. I had one light on them for about 2 weeks, the bulb is one of those spiral bulbs, a soft white. Recently i got another one. My plants have sky rocketed. One is huge, and i think is taking nutes from the other plants. One is getting brown spots on the leaves a little. Some of the edges are browning and dying it looks like. I lifted the lights in case of heat. My stems are getting purple, which ive heard good and bad things about. My big one is a deep green color, it looks amazing. A few others are getting a little light in color, not as deep of a green. They are in a rectangle container side by side, about 3 inches apart from one another. The tallest plant, my baby, is about 8 1/2 inches tall, the shortest is about 6 inches tall. Im just waiting to see which are males and which are females before i start killing some and making room. I havent done anything to the plants besides 24/7 light, good ventilation, and giving them clean purified water every other day. Can anyone tell me by what they have read if i need to change anything? Plz help

a bra try to keep your ph at 6.0 all the time

Alright, im new to growing mj, I have 4 plants that are about a week old, they are about 3 inches tall and are just starting to develop their second pair of leaves, but i was abit hastey in planting these seeds and put then im a coke bottle in only abrout 3 inches of soil brfore really reading much about growing, i can see that the ends of the tap roots are too long for the bottoms of the conainers by a few inches also the ends of the new leaves are looking a tiny but yellow are they too young to transplant yet? cheerrs

1) Picture of plant:






2) Growing indoor or outdoors: Indoor w/70HPS

3) Watering schedule: Water every day w/ 50/50 generic nutrients solution every other day.

4) Growing Medium: Bagged soil w/ vermiculite

5) What stage of growth: Vegetative second week.

I noticed slight curling/yellowing around 4 days ago and decided to flush and get new soil. The plant has taken the transplant well but I have never seen leaves curl under quite so bad.
I have reduced watering and fert. As well as raised the light.

Extended info: I do not have a Ph tester but will soon and the temp. is around 80F.

The two black things are 3" PC fans so you can put into perspective.

I have a good knowledge of horticulture and am an electrician by trade. But the indoor cultivation is very new to me. Out door is much more forgiving! Any experienced help is greatly appreciated.

Edit: Also, The area that is turned down away from the light is a lush green. Indicating that it is trying to hide from the light, But the temperature is ideal and the light is pretty far away.

Edit** This grow has been discontinued due to indoor ignorance and bad preparation. Let me read some more and grow with this site, Then I'll start a journal. Thanks to everyone for the help.

need help. I think its a MG deficiency but i want more opinions. The outer leaves are yellowing and the very tips are brown. All the veins are green. Indoor grow. It is on 18/6 cycle with a 400 watt HPS. It doesnt really have a watering schedule other than when it is dry and when the leaves droop a little. All the inside growth(newer) is fine. I am using this soil called Kellogg Grow Mulch. Its not the best ratio but better then all the others sold around here. I also noticed that this plant stopped growing new leaves on the outer branches and started producing hair like things. No change in lighting has occured for like a month. Any chance this is nutes burn?? let me know please.

Hello,

I believe that my plants are experiencing nutrient burn. Look at my pics and tell me what you think. I am keeping my res at 1800ppm. One of the plants is doing fine and has shown no signs of this problem. The picture of the smaller leaf, I thought may be a different problem, like heat stress. What is wrong and what should I do? I am running an aeroponic system with 4minutes off one minute on cycle timer. Temp is 65-85 and humidity is fine. One rack of plants is fine, doing well about a week behind the one I am having problems with. Different reservoirs for each rack, same nutes though. The only difference is that the one with problems has 1000 watts over it and the other has just 600. I am into flowering four weeks this coming Monday, with 37 days left as of today. Help please.

Thanks

Thorman

I will try to post a pic soon this plant seems healthy but it just doesn't seem to be filling out it seems kinda scrawny I'm using a 400watt MH they are on a 21/3 light sched also 3 florescent tube lights(they stay on 24/0), they are feminized super lemon haze seeds and are in week 5 of veg growing in hydroton using a "bubbleponics" system with botanicare nutes "grow liquid karma and sweet citrus" the nutes are refreshed every week and the entire reservoir is cleaned and fresh nutes are added every two weeks. the air temp is about 75 and the water is about 72 PH is 6.5 and we are using an oscillating fan I'm pretty sure the nute content is correct but they just dont seem to be as full and bushy as they should am i doing something wrong>? any help or advice would be great thanks
