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.

*nute1 - N 17.5; P 12: K 12

sorry for ur hermie dude, i never had them so far (thank god).i don't think its a good idea giving it nutes right after flushing it (as long as its nuteburn), i think u better leave it a couple of weeks recovering without nutes but like i said b4 i'm not an expert.Be sure whats the problem b4 start treating them coz it could turn out the other way.
yes the tobacco syrup works really good for mites.In my first grow my 4 plants were covered with spidermites, i made the tobacco syrup mixed some chilli pepper with it & like u said from the first spray many of them died & after 5-6 daily sprays over & especially under the leaves all of them were gone .

It's me again. I'm having big troubles with my nuteburned plant. It's been four days since I burned it. All big fanleaves are gone. All other leaves are curled and burned at the edges. Yesterday the plant started growing some new leaves, but today these new leaves also had burns... How come? I flushed it with a 4:1 ratio (water:soil) then once again with 2:1 ratio. I'm sure there are almost no nutes left in the soil. I keep the plant in shade, and I spray it with water.
The temp of the air under shade is still pretty high, about 35 degrees C (95 F). Could this be the problem?

If I don't do something to stop this, the plant will surely die. I can't think of any possible reason for the nuteburn to continue. I don't dare to flush anymore, cause the soil is very damp now, I'm waiting for it to dry out a little bit.

P.S. Also I want to ask - Is it safe to spray the nuteburned plant with a tobbaco/chilly syrup, cause it too shows some signs of spider mites... Or should I leave them and wait for the plant to recover a little bit before I spray?

95F TEMP IS TOO HIGH DUDE, heatsterss burns new shoots too, don't let temps exceed 84-85f. if u got nuteburn too don't give any nutes at all atleast till they recover & if u already flushed it well, don't keep flushing it always .check ur plants coz nuteburn starts from burning tips... if tips look ok green than i think its heatstress & when i had heatstress problems the fan leaves fell off too, but like i said b4 i'm not too experienced & to be sure u gotta do more readings.Mynamestitch's thread (the one we'r replying on)helped me more than i thaught http://www.icmag.com/ic/showthread.php?t=11688 but u gotta read carefully.I solved this damn heatstress problem w/ the AC .
& tobacco/chill syrup won't harm ur plants 100% even if u have nuteburn, just keep spraying daily till those lil mother fuckers r ALL GONE.
How strong did u make the syrup? I made it how i was told: 3-4 strong cigs, put their tobacco in water,let the water become brown,let it boil for 3 min & while boiling i added & spoon of chilli pepper powder, stir it, LET IT COOL OFF & u can start spraying.There r alot og good insecticide sprays u can buy but atleats when i had plants covered w/ them the tobacco/chilli killed them all.
Try & post some better close-up pix & more detailed info. goodluck with them! may they'll have a speedt recovery

Well today temps fell down a little bit. 85 F, the burned plant shows some progress in recovering.

The other plant is now starting flowering, developing well. However my nutrient with 36% K is low. So I need new nute for flowering. I need something with more P and not so much K. I was looking for something like 10-20-20, but I can't find something like that. I found 20-20-20 and 18-18-18 will those be fine for flowering?

Dude u'r going through the same shit i'v been b4 u , those high temps were making me crazy, my plants got half burned & leaves started to fall. If u'r not gonna do something to lower those temps u'r gonna loose them.Have u got atleast 1 good fan? i had 2 x 18 inch fans & still they got burned... it was getting out of control till i baught the AC.

i'm having the same thing, from where i live all i could find (exept for the low npk ferts)18-18-18 ,24-8-16 for veg & 20-5-30,14-10-27 for flower but (not enough P) so i asked someone & he told me there's a Miracle grow 15-20-15 but i haven't found it yet. if u coudn't find a good bloom (like i did) then i would use the 20-20-20. To tell u the truth for my next grow AI i'm thinkin of buying nutes online like BIOBIZZ or something similar coz here they don't get it (atleast i never came across it).

Well I don't use fans, because I grow on my balcony, under sunlight. And some days are just too hot. But the healthy plant is doing just fine, having no problems with those high temps. The burned one I keep under shade or in the room, exposing it to direct sunlight for just 1 hour before sunset. It's forming new leaves now.
As for the nutes, I found those in an agricultural store. Tomorrow I'll visit a shop for decorative plants, I hope they have something that is close to 10-20-20 with microelements. If not, I'll take the 20-20-20 (which also has micro's).

And something else, when I visited my outdoor plant, I saw that there were some ants over every plant. The plants themselvs dont look eaten or damaged at all (except a few yellowing leaves on the lower branches). But can ants be some trouble? Or are they just taking a walk over my babies?

Edit: Just now I found an online shop based in my country that offers the Dutch Formula 1/2/3 products (grow/bloom/micro), and all kinds of root stimulators and stuff at decent price. But I'm kinda afraid to order online, especially when the product is directly related to MJ growing. I'll do some research on the site, and how reliable it is, maybe next summer for my second grow I'll buy my stuff from them.

No dude ants won't harm ur plant & i hear they'r good for eating bugs like spidermites ladybugs too

about online nutes i guess u can order them for any kind of plants (i'v never ordered nutes online but i'm going for it) not just MJ. I was a little jumpy when i ordered my Aurora Indica seeds but its was cooler than i expected but i don't know how thing r in ur country, but just ordering nutes i don't think its something bad. Just to be safe ask someone from ur country that already had... better safe than sorry goodluck with ur grow dude! i hope u'll sort it out

Hi again, a little picture update. Here's the burned plant. Notice that even the young leaves are burned. And these leaves sprouted some time after the nuteburn and the following flush.



Here's me with the healthy plant (I'm not acting like a gangster or anything, that's just my eye/mouth/nose protection while I spray with the tobbaco syrup )




I tried to capture the budsites, but I just can't do a good macro



On Friday I fed the plant with a weak solution of the 36%K nute. It started showing some troubling signs (but not too bad.. still).



I flushed the container with 6litres of water (the container is 1.5). I hope this will prevent the problem. Seems to me that this nute is a slow absorbtion one, and builds up in the soil. I can't find any other explanation to the plants reaction to such a weak solution, taking in mind that last feeding was exactly 7 days ago.

The new nute that I've bought is from the same company (Nu3 BV Holland).
It's a 18-18-18-3 (last one is Magnesium).
Micro's are:
Boron - 0,025
Iron - 0.070
Manganese - 0.040
Copper - 0.010
Molybdeum - 0.004
Zinc - 0.025

For now I've tested it only on my plant ouside and it reacted well to it. But I'll wait sometime before I try it on my home plants.

Something else. A friend of mine is going to give me some BioHumus (redworm castings). I've heard these are very good, and especially for final weeks, after a flush. What do you think about it? It comes in pellets it usually has to be mixed with the soil before planting, but my firend told me thet they can be dissolved in water and added to the soil. He says that this fert can in no way cause a nute burn because it was 100% natural?
If it really is that good, should I just add it now, and forget all the other
nutes?

Edit: Damn, I just remembered something.... I threw the ashes of two charocals (left overs from smoking a hookah) to the pot. I've heard that they are good for adding small amounts of Nitrogen, without risk of burns. But is it possible for the charocal ash to have reacted in someway with the nute?

 

[StonedGrunt55]

DUDE U GOT EXACTLY LIKE I HAD its heatstress 4 sure. mine was exact the same way your plants r due to heatstress.
I'm sorry for ur problem dude but if u can lower temps U WILL SAVE THEM! atleast i did. & the same way i began to think all kinds of problems but now with the AC they'r lovely green again .




do something b4 its too late... i don't mean to spoil ur plans but leveling temps is ur only choise of saving them.
Forget the nute problem. I hate heatstress problem, it started to fuck me up.. Fan leaves & new leaves started to fall off from mine.

goodluck bro! hope u'll sort temps out

 

[Guest]

Well only thing I can do is to keep them inside with an air conditioner turned on...

As for the healthy plant, I don't think it's heatstress this time. It was just fine in much higher temps... Tommorow I'll buy a Ph testing kit and test the soil. I fear that the ashes might of raised the Ph up. If that is so, I'll try to correct it with lemon juice.

Edit: Just overnight more of the leaves on the plant started to show burns and curling... That defenetely isn't heatstress, because it was a cool night.
Buying a Ph test will be the first thing when I wake up.
Otherwise it looks exactly like Potassium def. If Ph tests are in the normal range I'll add a solution of my new 18-18-18-3 fertilizer.

 

[Guest]

I removed the top layer of soil, where the ashes were. The burn seems to be contained, no more burns have shown up in the last 12 hours. I'll fill up the pot with fresh soil.
Couldn't find any Ph tests today, I'll try a couple of other stores tommorow.

 

[StonedGrunt55]

ok do what u like!

 

[twistedtree]

Okay, I got one fer ya! I just checked my pH. I did two tests. The first test consisted of the soil in distilled water. pH was around 5.5 - 6.0. Then I tested the tap water I've been using since their birth. Holy shit, pH was a staggering 8.0+!! 4 out of 5 of my plants have yellowing in their leaves, and a few of them are starting to get little brown marks on the edges. I have 3 C99's and 2 Mikush's. Both Mikush's and two of the C99's are showing symptoms. Oh yeah, they're only like 2 weeks old. I read on here that lemon juice lowers pH. Anybody know what the ratio is? Or should I wait till they are ready for another watering and just water with distilled water(I bought 3 gallons for now)? Also, I read that hydrogen peroxide mixed with water helps deliver oxygen to the roots. Anybody know the ratio on that? Should the peroxide be used with just water, or can I use it in my nute solution? Haven't fed the plants yet, either. Just using crappy tap water.

 

[Guest]

well stir the lemon juice in water so it reaches about 6.5 Ph, and then water the plants with this water . Keep in mind that most nutrients lower the Ph.

P.S. I don't know how long you can use lemon juice though.

 

[twistedtree]

Hmmmm, interesting. What about the peroxide? Any ideas?

 

[Guest]

Hmm, not sure about peroxide... I remember that when we were kids we used this stuff to make our hairs blond. But I'm not sure how plants will react to it, and what dosage should you apply.

Why not buy a Ph - solution from a pet store (it is used to regulate the Ph in fish tanks).

 

[StonedGrunt55]

Vinegar also lowers ph... just a few drops (it depends how much water) .I'v been lowering ph with vinegar since day 1.

 

[Guest]

As we started talking about Ph, what can raise the Ph? I've found the hard way that ashes do that thing... But is there any liquid (that can be measured in drops like the vinegar) that could alsoo raise the Ph?

I've heard that if you take one eggshell, crush it to powder, than bake it, than add it to a cup of water and leave it overnight... The next day the water will be about Ph 8 (and rich in calcium)... but haven't tried it yet.

Normal tapwater here is about 7.5, so i fill a bucket of water, i leave it there for atleats 24hours to eliminate any bacteria,i add like 20 drops of vinegar & adjust the correct ph 6.5 (it depends how much water there is). Now i baught & ph+ & ph- from an Aquarium store.If u want any ph kits,testers or ph+&ph- u can find them at an Aquarium store.
I never tries it but they say Sulfer or carbonated soda can be used as ph+ BUT I'M NOT CERTAIN YET!!! i could be wrong!
but if your water has hi ph all u need is ph- ... gl
