Dank Demons Perpetual 3600 watt LED 18 plant SCROG

[Harry Lime]

You checked the ph meter yet Dank?

 

[Dope time]

What did you do different DD?

Those are the exact same symptoms as my c4d.Luckily only 1 is like that but the Brum cheese did take some damage can be seen on CL thread
Ph recovery can take a while! Imoe
Spose their all like that being NFT unless you individually sprayed them.Daunting to look at and can release demons (no relation ) I.e makes you look at things you normally wouldn't.In the past I've got rid and started again because of this
No clue what's Different!?


Never looked so good during this illness tbh but Many of the leaves went brown and Crumbled away and looked Identical to your Pics [they werent multi coloured like some are]

Slowly starting to Recover.
Nearly a 2lt flush last night [feared the Coir had gone Toxic]
ZZZzzz not moving for weeks.

1.6 EC is 1600 microsiemens? ~ 700-800 ppm.

I would try dropping the nute levels, whilst you calibrate your ph meter. Even if it's not nute burn (I think it is), they wont be using tons of nutes in that condition, so it won't hurt.

I have finished entire crops with out going over 1.4 EC, some plants are not heavy feeders. That size I would go with around .8 EC and work up from there. 1.8 - 1.9 EC is usually my absolute ceiling in pure hydro.

*you mention possible fixes: Dump the rez, I usually wipe down with a hand towel also. Fill res with enough fresh plain water to run the system but don't fill it to max, and adjust the pH to 5.8. Run clean water through the system for 10-15 mins... and dump it again. Fill it back, mix nutes to .8 EC and 5.8 pH. Good luck man.

do you think it could be anything to do with the lights?

 

[theherbalizor]

These lights require less feed. I have 2 massive pynamites under one 1200w in a 1m tent and they are happy on 1.2ec. Bass water is 04-06ec.

I would say your prob looks like nute burn and lock out.

In all honesty I would scrap them and start again. Keeping the nute levels right down.

I hope you get it sorted DD, goodluck.

What ec would you have the Pynamite under HIDs at this point, Herb?

 

[theherbalizor]

I run all plants from cuts to massive trees at 1.2ec no higher. Until week 2-3 of 12/12. Then I up it to 1.4-1.6 base ec. Add pk to bring it up to 1.8ec.

Whether hid or led.

I also find adding pk like sup potash at start of flower like recommended can hurt the yield. The buds just don't swell so much more calyx. So I now only add pk at half strength from day 21 then up to full strength a week or so later.

 

[Fields~of~Green]

I used to pump my plants full of nutes but over the past few grows I've been keeping them lower than I normally would trying to get better quality buds smoke wise and my yields have been better too

 

[DZLHIT]

In all honesty I would scrap them and start again. Keeping the nute levels right down.

I agree with starting over, the yield and quality in the end will likely be better. These still require a lot of down time to recover, you might not lose as much time as you think.

Hey Dank Demon,
Do you plan/ or maybe already have done anyting in terms of fimming or topping ? looks like they have enough room sideways for bushing out.
Do you raise your panels for taking pictures or is that how high above the plants they really are ?
IME you need to check the effective footprint of your panel and adjust distance to plants accordingly for best results with LED ( or any other lightsource). This depends mainly on the scattering angle of your reflector and the power of your individual LEDs.
I keep my panel much, much closer to the plants' tops for best results.
Pardon me if that has already been said earlier ;-)

Jah bless man and keep us posted !

Hey bro, thanks for popping by the disaster lol, yes I do fim and use lst and super cropping techniques then apply mesh screen. As for the panel thing then no the advice that came was to keep it 3' high above plants, and beccause I am an LED newbie I fell for it LMAO now they have been lowered accordingly. Thanks for the help and advice my criend stay tuned I will turn this around you will see.

Its on my job sheet for tomorrow mate along with a full system clean, plant flush and a 0.7 ec.

Hey bro, thats the million dollar question " what did I do different?" The answer is added LED lighting so now I know and now I'll fix it.

1.6 EC is 1600 microsiemens? ~ 700-800 ppm.

I would try dropping the nute levels, whilst you calibrate your ph meter. Even if it's not nute burn (I think it is), they wont be using tons of nutes in that condition, so it won't hurt.

Hey my friend, thanks for the great helpful advice, tommorow I will be on this like a fly on shit, and I will not fooking leave untill I fix it by using all the great advice on here from you guys

do you think it could be anything to do with the lights?

Hey my friend, hope your well, but I know one thing your bang on the money right there.

Peace

Hey my friend, I am afraid I am in the situation where I cannot afford to just chuck em and start again, I am a fighter and I will now with all this great advice from my friends solve and move on. I am now glad I have truthfully documented my trials and tribulations with LED so others can learn from it. Do you know hos much it hurts the pride to to take pics of your ladies looking in that state when you have been growing for years? Thanks for the help and support mate.

I hope you get it sorted DD, goodluck.

Yo, cheers my friend.

I used to pump my plants full of nutes but over the past few grows I've been keeping them lower than I normally would trying to get better quality buds smoke wise and my yields have been better too

Its great we can all still learn years on and as you get older change is jarder to do LMAO.

I agree with starting over, the yield and quality in the end will likely be better. These still require a lot of down time to recover, you might not lose as much time as you think.

Wish I was in the position to do this mate but all my mums are younh themselves and with crimbo around the corner, I have no choice but to fix this and like I have said loads of times, I could not have done it without my friends support and advice on here.

Stay safe, grow strong, and most of all "smoke on my friends"

Peace

 

[Dope time]

? Puzzled how could the LEDs do that

Chin up, Dank and have a smile at this...http://www.youtube.com/watch?v=cMqdwtd8TrQ

During first couple of weeks of veg I keep LED's at least 3 feet away and give them hardly any feed, dont really drop the lights low and up things until in flower same with the CO2 wouldnt use that either until into flower.

Hi DD, I'd agree with these guys.

I've seen plants react very similarly as a result of over feeding. I've also seen plants in a far worse state recover into healthy trees.

Provided you address the issue they will sort themselves out, they'll just take a little longer as others have mentioned.

I know the feeling of frustration when things start going downhill rapidly.

Stay positive.

Peace

Do you know hos much it hurts the pride to to take pics of your ladies looking in that state when you have been growing for years?

I sure do, and it's the best way for everyone to learn. So kudos to you for doing it.

 

[willyweed]

imho:get the hps back on them mate,the sooner the better,12 1/2 weeks to crimbo !
you are a star with the hps, figure these out after crimbo .good luck either way.
feel ya pain too,still one of my fav grow shows,warts and all.all the best.ww

 

[Dank Demon]

Hey peeps,

I am going to stick with the LEDs and get it right and return with better looking plants soon.

On a more positive note here are some pics from my cupboard SCROG at week 5 under a 250 watt sodium.
