Urgent help asap dying pls

The taco leaves means it is too hot and the humidity too low. The light green color indicates a nutrient shortage; this might be caused by the heat problem. The leaves cannot transpire water as they are shut down from the heat. No water no nutrient uptake. That HPS lamp is too close to the plants. Use the hot hand test. Hold your hand at the top of the plant palm down; if your hand gets hot the lamp is too close.

You need to go and buy a hygrometer mate they are less than tenner I'd be lost without mine solved so many issues for me.

SIDWAYS PICTURES


There is a long winded explanation why pictures from some digital cameras (mobile phones) load sideways but who cares we just want to fix it, right.


The best option is to upload them to your PC and run them through a photo editor. Save them as a small .JPG file and upload them to the forum.


No time, no PC, no problem. From here the path of least resistance from my investigation is to open the picture on your phone with free software, Google Snapseed (iOS and Android). Snapseed is highly rated. Open your picture in it. Rotate it and save it. Then upload it. You may find you need to rotate left, right, 180° or 360°. This is a bit of trial and error until you find what works for you. There are several tutorials on the web on how to use Snapseed.

This is a quick demo:

The plants hve grown tall towards the lamp i cant raise it anymore i think heat is an issue is there any steps i can. I cant get an air cooled hood or use air from the outside i have both vents open.

If you can't fix the environment man I'd axe the plants and start again when we get cooler weather. I'm assuming your in England same as me? Other thing would be using a 250watt dialled CFL grow bulb they are only £23 and £15 for reflector and fittings [emoji106]

supercrop, if you’re confident enough
search on this forum

seems harsh but your sunburnt ladies will love you for it

there are also some fantastic little plastic widget gadgets called BENDZ

cheap as chips
makes LST a doddle

But first ... get that environment sorted.
As I said earlier, the pics show girls who are screaming at you to get the Big 4 in order;

1. pH
2. heat
3. humidity
4. air flow

You have said they’re all “good”.
Your girls are telling a different story.

Environment ... environment ... environment.
Build it; they will come.

I agree that it looks like a heat issue with the top leaves pointing up and the bottom leaves wilting

Super Cropping

Hardest thing for a new grower to do emotionally and physically is to super crop a plant to keep it out of the lights. The problem is many new growers as well as all of us end up in that situation indoors sooner or later.

Have some grafting PARAIN TAPE on hand just in case. 6" lower than you think you should roll the stem crushing the inside 3 x the diameter of the stem in length between your forefinger and your thumb and bent the branch over at that pinch. Bend to 90° from the stem or horizontal to the light. If you did not get a good enough crush the stem can break usually just on the top. If this happens just wrap with the grafting tape and all will be well. You may need to tie down the bent over top as many branches just lift themselves right back up. A great lesson to teach yourself on your first harvest or any harvest for that matter is to practice super cropping on branches you have harvested. You will get a good feel for what it is to crush and bend without the dread of "Killing a Cola". Don't be scared in your case the plants might die without this technique.

Personally, I think this is recoverable. The plants are big, so the stuff at the bottom is not useful anymore. Cut all that lower airy stuff, and yellow leaves off and the plant will get better air circulation, and maybe supercrop the main stem, but I'd wait till they pick up a bit.

As @Mañ'O'Green said, water the plants well, wait an hour, work out which direction you want the stem to go, then give the main stem a good squeeze until you feel it pop inside. Do that up and down for an inch or two, then bend the stem to 90°, and support it. You will be fine and you wont regret it.

Regarding heat stress, I have to deal with this a lot. I switched from HPS to LED and that helped. With the HPS the heat stress caused a lock out, the plants stopped drinking and they wilted like yours.
So if that's happening to you, lower the EC by a couple of points and add some Kelp, the added micronutrients will give the plant a boost. The leaves won't straighten out, but the new growth should look OK as they recover. I used a fan to push the hot air directly under the lights up towards the carbon filter, and a nice big floor fan to push cooler intake air upwards into the plants.

Hope all goes well. They are amazing plants, and put up with all sorts of shit, usually bouncing back better than ever. Those large yellow lower leaves were depleted by the plant to help it grow. They have done their job so get rid. Same for the airy bud, strip it all off.....

let the plant concentrate on what's up top!

Day 30 is not too bad, they are just about to flower, so they need a bit of TLC and away they'll go!

MoG, Yoz and TT have you covered! I see drooping too, did that plant dry out badly, and/or overwatered? Both will cause wilting but for different reasons,.... Light/heat stress for sure, causing transpiration to slow way down, stopping the flow of wtaer/nutes from roots up..plant is forced to burn it's fans for those nutes that are mobile, but several are not... those will start symptoms on the tops,... do what you can to correct these things, or there's nothing but trouble to come of it,...
