Let's see and hear about your sick plants!!

Cool. Actually they should be done by now, had they not faced light pollution during 4 nights in a row at week 5 of 12/12 hence delaying the ripeness time. Ideally some might require 10 days more, but I need place for the new seedlings, so won't go beyond 7 days. 4im just a bit worried that 7 days might be a little short for the plant to absorb all the water that will remain after flush AND getting dry enough to stimulate the resin production. Hmm, wait & see...

Thanks for the help & tips jay !

Irie !

I confirm that there is no mold at all anywhere. So, most probably too much ferts as I thought first. But flushing might be risky as it will rise the humidity in the grow room to 90% if not more. I can only hope that by harvest time, the excess will have been fully processed by the plants !

Hello. I've been having issues with curling leaves and now even some browning taking place. Strains are 'lollypop' and 'white widow.' Grow room is indoors. Temps do not exceed 85 and stay above 75 fahrenheit. Plants are rooted in perlite, 5 gallon smart pots. They are on pallettes so they don't sit in the drained water/nutrient. Drainage is relatively swift in perlite but not immediate. I've had very good luck with perlite as it allows the roots to uptake nutrient but also allows them to breathe before next feeding. A timer controls their feeding at about 35 seconds every 8 hours. I've been flushing the plants every couple weeks with clearex http://www.planetnatural.com/site/clearex.html. Plants have shown instant happiness after each flush. I'm using House and Garden brand nutrient - pretty expensive, high quality stuff. Have had good results so far and have witnessed excellent, perhaps amazing, results in other grow rooms. I keep my nutrient mix at 5.8 to 6.0pH and PPM has been upped every couple weeks starting at around 850, then 950. I'm at the end of week 5 of bloom stage and PPM is around 1100.

A couple weeks ago leaves at the top began curling inward and twisting around. I was hoping they just needed another flush and gave it a try. They responded a little as the twisting reversed itself but the inward curling remained (see pics). I thought maybe they weren't getting enough magnesium so I mixed an epsom salt solution and added that to the nutrient. I also raised the lights since they seemed a little close to the top and only the top leaves seem to be affected. I also noticed some of the top leaves further down are beginning to curl but they're definitely far enough away from the bulb that there's no way they're getting burned.

Bulbs are 1000w sodium. Tallest plant is 4'4" and distance from bulb to tallest buds approximately 20". Not having any problems with pests right now. I have a strong exhaust fan so humidity isn't an issue. Not sure what else to do. Any suggestions would be appreciated.

Attachments: 1st two pics are lollypop. 3rd is a widow. 4th is a lollypop bud towards the middle of the plant.

I posted this elsewhere, but due to the lack of pics, I think it's getting over looked. Thought I'd try here. I posted:

I started some Afghani seeds that are at 28 days from the day I started germinating. Had some PH issues at first, but have cleared all of it up.

I am growing in a mix that consists of EWC, Guano, MG Organic Choice Potting soil, and lime. There is also mycorrhize in the soil, or was put there when putting the sprout in.

I have only given them a real water once and that has seemed fine with some light foliar feeding. They are on a 18/6 schedule.

I have 4 of these and plan on using Fox Farm tri-nute line-up on two and the General Organics line on the other two. I haven't given the plants any nutes aside from what was in the soil when I mixed it and I followed the ratios provided by an experienced grower, but I ph'ucked up by adding too much lime. That has been fixed.

My plants had PH issues, so I understand that they are growing a bit slower, but they seem to be really short at 4 weeks. They are about 3" tall and about 18" away from my 400 watt MH Sun System 2. Temps range from 75-80 during the day, but have dipped to 65-62 at night. Humidity is at 40% but I bought a humidifier today. All this is in a 4x2x5 grow tent. Soil PH is at 6.8-7.0.









The yellowing was from the PH lockout and has since stopped. As of today temps were 75 with RH at 55%.

Please help.

 

[eleven11]

themoon: are you using straight soil or a blend? how dry does the soil become before feeding/watering? what pH did you have when you experienced lockout?

based on your info they should have plenty of light but are they getting nitrogen? I guess if they have a good solid shade of green without yellowing then they are. I'm also curious about your pH because my experience shows that a pH around 6.0 is where you want to be. 5.8 is supposed to be ideal. I haven't used straight soil, though. I only use perlite or sometimes a blend. also you might want to bring the temps up between 70 and 85. cold temps can slow them down.

hope this helps

The soil has at least 50% perilite/vermiculite. I had guano in the mix and EWC for nitrogen. The soil becomes really dry on top, but not on the bottom. I had them in 6" pots too early.

My soil PH is about 7.0. I was told that 6.2-6.8 is ideal for soil, but I don't know. They just seem small for their age. I have G.O. nutes I will be using on their schedule. Actually FF nutes on 2 and GO nutes on 2. I experienced lockout at 8.0 PH.


PS- They are in 6" pots right now, but I thought that when I move up to sizes I want to use coco. Would this be possible? I can get more soil mix at the hydro shop. I'm going to start running half coco, half soil mixes. Also, all vegan soil mixes and nute lines.

 

[Chronic777]

Anyone know what this could be?

It came after a second big feed, so im thinking its gotta be nute related, perhaps macronute toxicity?

When i was watering before with just water the plants were fine so i dont think its PH related( although i did get the odd yellow spot & slight interveinal yellowing) but i dont have the means to test my water PH yet

 

[eleven11]

themoon: Okay you mean soil pH. I only check the pH of my water/nutrient mix. Since I don't use soil, I can't really speak to that. I have not tried those nutrient brands yet, but I'm sure most of them do fine and most of them might require some augmentation, i.e. adding some magnesium or giving a periodic flush to get rid of salt buildup. I'm not sure what coco is but I'm guessing it's a medium. I think a lot of this is trial and hopefully success to see what works for you. I have narrowed things down quite a bit and am sticking to a system with relatively expensive nutrients. I had sticker shock at first but I'm finding the pain of dealing with lower quality nutrients and sick plant diagnosis is not worth it. I think your best bet is to stick with a plan and document your success and failures so you can narrow down what works best. It also helps me to only use clones, no seeds, and stick to one strain (though I sometimes break that last rule). Based on what you describe your only problem is that they're growing slowly. My best guess here is your growroom temperature dips too low when the light is off. If your plants are otherwise hearty looking and green you're probably doing fine. If the roots are busting out all over the place then the plant should be in a larger pot to help it grow. I purposely keep one or two mothers around in plastic cups and I'm able to keep the plants smaller that way. Sorry if this is all ridiculously obvious advice for you, I just try to cover the basics unless I can pinpoint something specific.

 

[eleven11]

chronic777: I've never encountered that specific type of necrotic patch. It might help to post some more information about your setup. I can only guess you have some nutrient burn happening. Do you have a way of checking PPM (parts per million)? The size of your plants and your growing medium should dictate a general PPM window. I would highly recommend a digital pH meter / PPM meter combo. I know it can be expensive, though, if you can't get one then you might want to scale back a little, i.e. if the bottle says add one cup, maybe add 3/4 instead. I've found many nutrient brands suggest a concentration that ends up being too high for my plants. Is that ironic?

 

[Chronic777]

I guess if my nutes were like that and i added 1ml extra, then thats my problem here

 

[kerlito]

what do u think?

what do u think?

i don´t know what it´s wrong with this one, she grow up like the look she have right now

hindu gone wrong

hindu gone wrong

kerlito you need to post some stats on what your using.

meanwhile can anyone help with this one im using gh 3 part 3-2-1 in bcuzz coco and canna coco separately and it seems to be happening to both. my ph is 6 with water at room temps. no more then 5 to 600 ppm ive done this before with the same strain of hindu and got beautiful results but now not sure what the hell is going on.

Well I've been battling several issues from the beginning. In an outdoor shed and now it's bloody 25F outside. Had to add a small space heater. Initially it got down to 55F for a couple days before I added the heater now the heater stay on using a thermostat so the room temp is around 80F and the soil temp stays right around 70F.

Had the lights on 18/6 now on 24.

I know my soil is screwed and I've ordered some coir to try that. But I'm just wondering if these are worth messing with. These are 5 weeks and terribly stunted IMO. Also, do these PH meters work? Just put a straight tepid rain water flush on these so they do look over watered but you can see issues with the leaves. One actually brittle yellow spots with holes. The other has tips yellowing/browning.

Soil is 25% perlite, 50% MG Organic and 25% manure. I know. WTF was I thinking. So the runoff of the water is basically the same 7.

Feel like I seriously wasted some time with these. 5 weeks and they should be ready to flower. Sorry if I'm rambling.

[dman16]

need some help with this girl. Bought her looking decent now looks pretty pathetic. Her leaves first drooped big time and then some leaves got crispy and i did a little pruning 2 days ago. I also transplanted 3 days ago to the current pot from soil and it had somewhat decent white roots (nothing like my other plants though).
Im scared to feed it anything until its roots establish a little better, its in CANNA coco with perlite (70/30 roughly) and was fed a 300ppm 6ph solution yesterday of a little canna a+b, cal mag+ as well as a decent dose of rhizo. Ive also been spraying it with a 7ph foliar spray with just RO water and rhizo in hopes of boosting some root development. Any advice is greatly appreciated i really wanna save her

 

[tjann]

Hey, Dman.
I think the cause of this curling could be due the distance of your light source. How far away from the "sun" is the plant?? And again, what are the temperatures in the height of new growth? I think it could be too hot for her there???
Greetings
