plants look f#@ked up

hey guys i was wondering if anyone has this before. what hapend was there was a 2 day power outage and then again today for a few hrs.

the ph and ec are fine any ideas whats wrong with these 2 plants? they look like they are falling apart.


here are some pics, let me know if you need more

I'm gonna say it looks like iron, because magnesium would start from the bottom up.....You can look for yourself, though....https://www.rollitup.org/view.php?pg=faq&cmd=article&id=36
Maybe even a ph fluctuation..what ph water are you watering with?Any nutes?EDIT: could be potassium, too.
Iron
An Iron deficiency will mask a Magnesium deficiency. If you look at the newer growth, that will be where the plant exhibits the intervenial chlorosis typically differentiating it from a Magnesium deficiency.







Notice how the top of the plant is exhibiting intervenial chlorosis and the lower part is unaffected.
pH Fluctuation:
Both of these leaves in figure 6 and figure 7 are from the same plant. It could be over fertilization, but more likely it is due to the pH being off. Too high or too low a pH can lock up nutrients in the form of undisolvable salts and compounds, some of which are actually toxic to the plants. What then happens is the grower then tries to supplement the plants diet by adding more fertilizers, throwing off the pH even more and locking up even more nutrients. This type of problem is seen more often in soil mixes, where inconsistent mixing of the medium's components leads to "hot" spots.


Figure 6 (left) and Figure 7 (right)

Potassium (K)
Potassium is involved in maintaining the water status of the plant and the
tugor pressure of it's cells and the opening and closing of the stomata. Potassium is required in the accumulation and translocation of carbohydrates. Lack of potassium will reduce yield and quality.
Potassium deficiency:
Older leaves are initially chlorotic but soon develop dark necrotic lesions
(dead tissue). First apparent on the tips and margins of the leaves. Stem and branches may become weak and easily broken, the plant may also stretch. The plant will become susceptible to disease and toxicity. In addition to appearing to look like iron deficiency, the tips of the leaves curl and the edges burn and die.
Potassium - Too much sodium (Na) displaces K, causing a K deficiency. Sources of high salinity are: baking soda (sodium bicarbonate "pH-up"), too much manure, and the use of water-softening filters (which should not be used). If the problem is Na, flush the soil. K can get locked up from too much Ca or ammonium nitrogen, and possibly cold weather.

looks almost natural to me seeing your probably around week 5 flowering keep your 12 hours of light on it and let it ride out not too far from harvest i can see. the lights probably stressed it in some way but keep it up

First thing that comes to my mind is light stress. If you're in flowering, and they have no light for two days, IMO thats going to fvck them up. Could be a nute problem in addition to it tho.

thanks for all the responses ph is 5.9 nutes are advanced nutes in hydro nft

I don't do hydro...but an earlier response said some nute deficiency is normal during flower, and they're right, I should have mentioned that.I'd say, when in doubt, give 'em a flush and wait a couple of days and see.

im going to wait till tom. and see how they are doing i might just leave them on the nutes if they are doing better tom. if not ill give them a flush.

Could be a lot of factors here.. one thing to get out of the way is the effect of 2 days without light.. really its not as bad of a problem as one would think .. plants should be fine without light for 2 days BUT will decrease yield slightly in the long run.. If I had to guess (limited info), I would say that this is either (or combo of) light and/or heat stress (up-curling leaves).. especially if they are turning brown, drying out and/or cracking when touched.. otherwise, it could be a nute problem.. see nute deficiency problems.. right in the middle of flowering, most strains will radically and suddenly change the management of their nutrient levels and need more soluble potash along with other 'bloom' nutes.. I would snip off the dead/dying parts and then flush and take a temp measurement at the leaf zone (if too high, raise the light), give ph adjusted plain water for a week then do 1/2 nutes (emphasis on bloom nutes) then increase up to one week before harvest (at which time, need to flush).. good luck!

i appreciate all u guys help rep points have been given. one thing i want to stress is the wierd down ward curling leaves that look like they are dying worry me the most.

its getting worse a few more look like they are dying, leaves are curled over and feel like they are wet paper.

will post pics here shortly

here are the pics

flushing with plain tap water right now. ph 6 going to let it run on just water for a few hrs then planing on adding qtr nutrient solution this evenig. should i wait to add nutes a few days or should i put them in?

ello m8ty i would wait. the other pics look like a mixture ov things light too close? do u have a fan on em? good luck m8 anyway

I plant my weed seeds on friday how long is go to tack be for i can skom it?

what ph should the flush water be at?

Probably flush them with water ph'ed about 6.8 if you're using soil.

You know, the more I think about it, the more I think that the lack of lights is what caused this. If you think about it - plants need light for photosynthesis. If they don't have that light, they're not using the nutrients that are in the soil like they should be, so that probably resulted in a salt buildup.

Regardless, good luck to ya man. Flush em out, and give them a few days before you add nutes again, and start at half strength when you do feed them.

I noticed that one of the plants was infront of the intake tube,what is the temp comeing in the grow room at that point.i have had plants go like this when the temp is a little cool.this is def heat or temp realated.the plants look like they are a good few weeks in so there is not that much that you can do.but i would say keep a close eye on the temp ph flucktuation,some of the leaves are canoeing this is caused by heat.i would sat flush them but you have supportnetting up this is why i tie each plant to the walls of the growroom takes seconds to get a plant out to flush.i think that even at this stage of growth the plants that look bad may come on better if you flush them.people seem to think that plants only need one flush at the very end of the grow i flush at least 3 times during flowering and twice during veg this will get rid of any excess salt build up.

flushing with plain water right now, should i spray them with anything? looks like a molybean deficiency by looking at the guide. what u guys think?

bumb bump bump

I have a big problem. WE put my plant's on 12/12 one died and one look's like sh-t the leave's are dieing I think they got over fed so I flushed them with water they still look like sh-t I need some help please!! Does anyone have some input?
