Plants in total darkness for 3 days! 5th week of flowering! PICS included!

Hi there again!
My plants were nice and green, no major problems till now, until I went on vacation a few days ago. A friend of mine watered them while I was away but as I watered them before leaving, he only came by 3 days later. When he arrived, my 400w HPS wasn't working so the plants were in total darkness for 2 or 3 days. After solving the problem, they were watered one more time (this one with nutes: BioGrow, BioBloom, Top Max and Hesi Super Vit). Some of them are looking good but some others have yellowed some of their top leaves and some of the pistils started going brown. One of it's main colas has its top yellow.

So...
#1 Will they recover? Will the top yellow cola recover?
#2 Are the brown pistils dead pistils or are the buds maturing?
#3 Should I do anything about all this now?
#4 In how many weeks do you think they'll be ready to harvest? I'm quite unsure when to stop watering since they are bagseed.

Some pics to help you out:

Pics 2,4 & 9 show the damaged leaves. Pics 5 & 6 shows the yellow cola though it isn't easy to see with the HPS on. Pic 1 show it again, one of them with the HPS turned off.

Pic 8 shows the brown pistils.

Pic 7 is an picture of them and pic 3 shows one of the healthy colas.

Any help would be appreciated!

Cheers!

Any suggestion?

They will likely recover but not add on alot of weight for the rest of flowering if they are in alot of shock. It will definately affect your yield but you still should have some bud to smoke...

what about the brown pistils? Are they dying or getting mature? They are mostly in one of the healthiest plants...

They look severely heat stressed and burned. 2-3 days of darkness didn't do that....!

they look so stressed out and overfed man but if you flush with a mild sonution for a few days they might recover..

and i agree with 303 that was not the darkness that caused that it was you trying to give to much to soon

....maybe cut off some of the burned up stuff too...the rest should make it

If I saw the pictures I'd say the same but it seems unlikely as they are being fed this way for about 3 or 4 weeks and one week ago they were all green and healthy. For the period I was out, they were watered once and fed the day I arrived so it's weird. In the middle of it all, they were probably 3 days in total darkness.
Anyway, I'm feeding 2mL/L BioGrow, 3mL/L BioBloom and 1ml/L TopMax. Is this too much? As I said, they were fed this way for 3 or 4 weeks with no problem at all.
I flushed them today, waiting to see the results.

Thanks for your help!

Whats your watering/feed schedule?

day 1: feed
day 3: water
day 6: feed
day 9: water
and so on...

It looks like when you turned the light back on after 3 days of darkenss your plants got severely burnt. After 3 days of darkness they needed to be slowly brought back to the full intensity of the light.

Hmmm, does this mean that you agree with me or you think I am talking shyte - difficult to tell

Yeah, hard to tell.
Still, after listening to a lot of people saying it is overfeeding, I agree with you. I'm almost 100% sure I didn't overfeed them. They were nice and green before this incident... plus, the bottom and middle leaves are fine so... I really can't imagine such a severe nute burn at the top with the rest of the plant being fine.

They've been overwatered, as the light was off for 3 days, the temp of the soil and the rest of the grow room was reduced, therefore water stayed around longer than it would if the light was on. Not all water that goes into your soil will go into your plants. Some water will evaporate from the soil due to the heat from the light. The damage is so severe as they were watered more than once in reduced temperatures. Cold soggy soil prevents oxygen getting to the rootsystem and locks out various nutrients. Try watering less frequently and or reduce the amount of water you put into them, oh and use 3/4 strength nutes.

Oh and good luck!!

Thank you! I think that might be the explanation. They were a bit overwatered on purpose before my departure so that my friend would only have to come over a couple days later. I adjusted the light before departing too, to prevent heat stress as they grew. Probably that disconnected the light and they were in a colder, dark room. My friend watered them a few days later but the soil probably was still wet. Thank you dude!

never leave your kids alone at home with some else to take care of them. I can guarantee that no one will care for your plants like you do. I know you don't want to hear that right now. I hope you salvage some of that bud brother.. Happy growing.

i agree that they look over-fed. they seem to be exhibiting symptoms os nitrogen toxicity, which could be dur to using wrong/too much nutrients. flush plants with enough water to fill the container 1.5x. first, add 1/4 of the total water of the flush. let this set for about 15-20 min to dissolve nutes. slowly add the remaining water for the flush. after flushing, i do not feed till the lower leaves begin to yellow. they may also be heat-stressed, as the leaves are curled under, but i'm suspicious your friend simply added too much nutrients for them to use.
