I have a post in indoor soil grow trying to figure out what was up with my plants. My problem looks nearly identical to your picture of warm to cold scenario, warm days cold nights. Im indoor running at about 78-82 in the day. With lights off its right around 72-76. Is that really that much of a fluxation? Will it do much harm to the plant? Is it possible im misdiagnosising it? It looks nearly identical to that picture thanks for your help

TNKX A WHOLE LOT DUDE, This will help me on most of my problems i'm having..









but i'm not sure what's up..could be alot of things!

 

[MynameStitch]

Stoned what wattage of lights are you using and what lighting setup? NUtirnets? How big are the plants? Strain? How much nutrients are you using? How often?

i found out its HEAT from your info & other sites i'm getting an AC for heat coz temps here r high 95F.

i use MH 400w,miralegrow fert NKP 24-8-16,14-16inches tall 48days old ,switched 12/12 at 45days ,chronic x unknown,ferted them evry 2weeks started with 25%,feed them evry 4 days 2-3 leters tapwater each after leaving it for 1-2 days with correct ph,mist them 2-3 times a day,organic soil mix,temps vary from 84-95f .
sorry didn't write it b4 i was so pissed i started posting threads evrtwhere lol.

 

[MynameStitch]

Ya I was going to say it looks more like heat issues but I did not want to say for sure yet untill I get all information. Glad ya got it fixed though!

Greetings from a newbie grower. I'm in need of help.
This is my first real expirience with MJ growing, it's fun but also kinda demanding.

So first some info:

So I am at the 43rd prallel, it's a really hot summer here, I am growing them on sunlight. I started this batch in mid-may. In mid-june i transfered a few of them to an outside location and planted them there... Two survived. Two more are at home, growing on my balcony... And I have 4 more outside of town but they were started earlier (mid April).

The nutrients I am using:
1st one is: N 17.5%, P 10%, K 12%, Mg 0.06% it's a nutrient for flowers, but I guess it's good enough for weed too
Second one is: N 12%, P 12%, K 36%, Mg 1%, S 2.5%, and other micros below 1%, it's a nutrient for vegetables (eg Tomatoes).

So first troubles I had were with the plants that I transfered and tranplanted outside. They had a really hard time adapting, they struggled for a month. In the past week they started looking healthy again and continued their growth. Although when I took them out they were the biggest of the batch, now they are far behind the plants back at home... But at least they're alive
Here are pics of the heroes They are exposed to sunlight from 9am to about 6pm, average temperature is ~33-38 C under shade. They are about 20cm tall.
Still no sex signs.



So enough of them, they're actually fine for now. Here are the plants at home (pics from two days earlier). The ones back at home are each in 1.5 litre containers with soil bought from a store. I now start treating them with nutrient 2 once every 10 days (because of the high content of potassium). They're exposed to sunlight from 2pm to 8pm. Watering them when they need to (i test the soil 5-6cm deep with my finger). Done some cutting of lower leaves, and some upper to expose more bud tips to sunlight. The're about 35-40cm tall. They're both female



While looking more closely i spotted this:



grey/white spots on the leaves, consulted with the sick plants thread, then examined the leaves with a magnifying glass... Spider Mites. So I soaked 4 medium strength cigerettes last night, today I boiled them for 3 minutes, added some soap, and sprayed the leaves with the so called tobacco syrup. But as I've red the description - these mites can build up a resistance to the tobacco syrup. So I want to use some insecticide to be sure I get rid of them. Problem is I'm outside of USA, and pesticide products here are with different names. I am sure I can find a good subtitute, but I need some info. Since I can't ask in the store "please give me something against spider mites, but to keep my MJ smokable..." I'll have to ask about some other plant, that also can be infested by spider mites, and is eatable... Like tomatoes? Or if you have an exact chemical formulae of some insecticide that does the work...? I would be very thankful if someone can help me find an appropriate pesticide to get rid of spider mites.
And I hope tobacco syrup will do the work for the following couple of days.

And another problem... nute burn, which I made yesterday out of stupidity
Started preparing a solution out of nutrient two (the one with 36% Potassium), for my outdoor plants. So I first dissolve the nutrient in about 1cup of water, the fill up the entire bottle... And I don't know why (probably cause I was high) but I poured a little bit of this 1cup (high concentration) onto my plants at home. Then headed for the beach. I returned 2 hours later and I had 1 very badly burned plant (the other one seems to be fine)... Probably because they were exposed to sun at this time, a combination of nuteburn/heat stress has occured. So here are some pics, that I've just made with my phone (sorry bout that but I don't have a camera right now).

Burned plant:


a close up:



and the other plant which is fine, but I give it just for refference:



This blue bottle contains the tobacco syrup.
So I flushed the soil with fresh water a couple of times, and I;ve removed 5-6 leaves that died. There are more leaves that look bad enough, but I dont dare cut anymore, I'll leave the poor plant with very few leaves
I don;t know what to do, should I cut, or leave them?
Another problem should I expose this plant to sunlight, or leave it in the shades for a couple of days?

Sorry for the long post, but I wanted to explain everything.
And also please excuse any mistakes I might've made, my english isn't very good.

Edit: I'm now thinking... Maybe in a few days after treatment with tobacco syrup, I should start flowering the healthier plant. Sun comes out before 6am, but doesnt hit the plant until 2pm... So I'm thinking about covering the plant with a carton box before I go to bed (somewhere after 1am) and removing it when I get up (about 11am) that should give a longer dark period to the plant and encourage flowering... Actually it already has pre-flowers - batches of up to 7-8 pistils around the tops....
What do you think, will this work fine?

yellow leaves with brown spots

yellow leaves with brown spots

hey guys and girls,
i started my own grown box and planted a seed. i used an old record/ stereo cabinet, you know the kind with the glass front door. anyway, my plant is almost 2 months old and i have some very yellow leaves with brown spots. it has been very very hot here the past couple of weeks, so i thought the brown spots were due to burns from too much heat. i opened the door and used a huge fan to cool the plants. then some leaves started to turn yellow. i have been reading mixed info on this. some people say it's not enough nutrients, others say that it's too much heat, and others still say it's natural and not to worry about it. also, my ph was a little low(5.7), so i added coffee grounds to the soil to bring it back up and i also added some ground up egg shells for calcium to make it grow a little faster. i added the coffee and egg shells after the yellow/brown spots started. if i could get so advice from any one with knowledge on the subject that would be great. thanks guys.
p.s. the only leaves it affects are the older bigger "fan leaves" the newer leaves look fine

 

[MynameStitch]

R blunt I am not sure what some of the products are over there; but if you can get some sticky traps; they are like fly traps but you hang them near the plant.... get a stick and get one of those keep a few near the plant; it helps a ton when getting rid of those bastards. You always want to use 2 types of something to get rid of those mites cause you don;t want them to get the head start or you will lose the race!


Northwest it's not natrual for the plant to yellow in veg, end of flowering you wantr them to have yellowing leaves; but definatly not now.

You have a nitrogen issue, how often are you feeding your plants and what ar you feeding them? Also before I can give you an answer to as of why i need to know if you tested your ph and what soil are you using?

Most likley it looks like it may be caused by not enough nutrients

I will ask a few people I know who live over in europe what kinds of names you can use to prevent and kill them; or anyone else who reads this post can most defiantly chime in

 

[Guest]

Thanks for your answer, i'll try to get some of these sticky tapes.

Just one more question, about the nute-burned plant... Should I expose it to sunlight, or keep it under shade for the next few days. And after I flushed it, should I add a weak (1/4 strength) nutrient, or leave it on plain water for some time?

 

[northwest mj]

i'm using Alaska 9-4-4. i water, wait 3 days, then water w/ fertilizer, then wait 3 days and start over

my PH is 5.8, tested with a hand held soil meter

i'm using potting soil bought at ace hardware, no nutrients in the soil, completly balanced

also i moved the plant closer to the lights. it's about 6 inches away now. we did have a hot spell where it was getting in the upper 90's, but that has passed not

hey i live in europe but like u said u have to use 2 things to really get rid of bugs.in my case i use Wood's Fungicide a product of europe (it eliminates rust,mildew,black spot & other fungal diseases. kills white fly, black fly,green fly,caterpillars,thrips,mealy bugs,red spider mite & others) & some tobacco/chilli pepper jiuce aswell. i had spider mites,thrips,white fly & fungus gnats, with fungicide & tobacco jiuce i managed to get rid of them & for fungus gnats i even put some building sand on the top soil. I had used some sticky traps but i don't anymore coz they'r too fuckin sticky.

The nuteburned plant is dieing... There isn't even one unaffected leaf now.
I'll try to spray the leaves with fresh water, and keep the plant in shade for today.
If the burn continues, the plant will be dead by tommorow.

StonedGrunt, can you please look at the back of your fungicide, and tell me what the contents are?

P.S. Something else... I just examined my healthier plant and saw two tiny balls on it, near the tops... Hermie? I took one of the balls off (which looked pale green, almost white), pressed it between my fingers but inside there were green thingies. So I guess this isn't a pollen sack. What could it be? maybe a young flower or something?

I'm not an expert but if it has nute burn u better flush it with 3 galllons of water right away.Fungicide contents 800ml.
about those balls u'v seen, if u already saw pistils & now u'r seen balls IT IS HERMIE but if u seen only balls its male. good luck!

 

[Guest]

Yep it's a hermie... It already has pretty much pistils. I've red that if I carefully rip of all the balls the plant will still be smokable... There is just one ball now (I ripped of the second to examine it)... I hope it wouldn't produce too much.
As for the spider mites... The tobacco syrup seems to work really well from just one spraying. Tomorrow I'll spray it again. But most of the black dots under the leaf are gone, hope I caught them bastards early

About the nute burned plant, I flushed it already with a ratio 4:1 (6 litres of water for 1,5 litres soil), and added a very weak solution of nute1* about 1/6 of the normal concentration. I hope it starts growing new leaves soon, because 80% of the old one are damaged, and will eventually die.
