Dear Breeder Steve,

How ya doin? First I would like to say that LUI is one of the BEST strains ever created :) I have been growing her for about 5 years and never had a single complaint about her. OK I have a slight situation and could really use your help if possible, I took a year off from gardening and about 8 months ago I decided I couldn't take it anymore and sprouted my last 5 LUI beans, all sprouted and I think I ended up with 2 mom plants (1 of each pheno) so I got my babies cut, rooted, put into vegging for about 2 weeks while feeding them fox farm grow big (1 tsp per gallon). I think I watered them a total of 3 times during veg, same ratio every watering, so nex I flip my lights off for a total of 48 hours to induce flowering, so far everything is great, nice dark green and beefy as heck, so the first 2 watering's I am giving them ff grow big at 1\2 tsp per watering, still doing great and starting to see flowers, so I figure its time to start with my bloom food. The bloomer I am using is advanced nutrients sensi bloom parts a and b, plus I decided to add molasses to my water which I add 3 tbls per gallon along with one and a half teaspoons per gallon of my an, So this is the first watering with bloom, so with about 3-4 days of watering i start to see a yellowing starting on my big fan leaves and its getting worse, at first I thought I was having a def of nitro so a few of them i hit with a normal dose of ff gr (no improvement) so I decided to foliar spray with ff gr a few of the other ones (still no improvement) nex I decided to leech my pots and see what would happen, leeched them and still they seem to be getting worse, the fan leaves on top are turning yellow and dying, I see no pattern in they way they are dying just that it is only affecting the fan leaves... HElPPPPPPPP what am I doing wrong??? I work my ass off on these girls and could really use some advise and or pointers. O and by the way they are under 2 1000 hps lights, temps are usually at a high of 87 degree, rH is right at 50-52% and my co2 is 1500-1550 ppm, I know im not burning them with the lights because its affecting different parts of the plants. any help would be GREATLY GREATLappreciateded because I LOVE this strain and refuse to give up on her. Thank you for taking time to read this long email and If you wanna see some pics I'd be more than happy to share

Feed/water/water. Kinda hard to tell from the pics. But from what you have stated you have fed/fed/fed/fed with no straight waterings inbetween. They are nute burned. And possibly caused some lockout issues due to salt buildup in your medium.
 
ya but I always feed light and never have a problem during veg and I feed every watering during veg. ps sorry bout the junk ass pics had to take them with my phone cause no other cam available. and I use promix straight from clone
 
Did you use FF products in the past? I would just go with water for a week or so and watch the new growth.
 
I have used ff grow big for about 7 years, never had a problem with it but i did have a problem finding the right ratio with their organic bloomer so I have been using AN for a couple of years and actually they are growing fine it's just the fan leaves that are dying and I know someone is prolly gonna say fan leaves die during flowing but not the first 2 weeks into it
 
and I flushed my soil almost a week ago still with no improvement to the fan leaves, they are still dying off. the pots seem to still be completely wet from the flushing that was almost a week ago
 
Try taking some pics right after the lights go out, just using a regular light source. They my share a few more clues.
 
I have a air conditioner running, keeping it about 80 degrees with the lights on, my environment is sealed with no outside air but I am using a co2 burner that keeps it at about 1500 ppm, and rH is 50%. I have a good environmental controller so I know what the exact levels are. But you could be on to something because since i have leached them the containers haven't dried out much, they still feel like i just watered them and I haven't watered them in like a week so i put a couple of fans on them to try and dry the soil out a little faster
 
Flushing will not put an instant halt on the damage. The areas of the plant that were affected will continue to decay. The newer growth is what you need to be watching. edit: I am looking at it this way. At first you thought it was N def. So you fed it more and it continued to get worse. So you foilar fed it yet more and it continued to get worse. Compounded the original problem. Then compounded it again. It will take awhile to recover. Just my opinion.

new growth seems to be fine, its just the fan leaves and I know with no fan leaves the plants aren't gona grow worth shit.
 
what about when they change from veg to flowering, what are your people's opinions on feeding during the change over phase from veg to flower??
 
I have never had nutes last longer than 90 days so cant comment on that but, the transpiration assumption is based on issues with the fan leaves, as stated the plant is growing and producing new leaf.Transpiration is the evaporation of water from plants. It occurs chiefly at the leaves while their stomata are open for the passage of CO2 and O2 during photosynthesis. But air that is not fully saturated with water vapor (100% relative humidity) will dry the surfaces of cells with which it comes in contact. So the photosynthesizing leaf loses substantial amount of water by evaporation. This transpired water must be replaced by the transport of more water from the soil to the leaves through the xylem of the roots and stem. Transpiration is not simply a hazard of plant life. It is the "engine" that pulls water up from the roots to:
  • supply photosynthesis (1%-2% of the total)
  • bring minerals from the roots for bio synthesis within the leaf
  • cool the leaf

Environmental factors that affect the rate of transpiration

1. Light
Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (mechanism). Light also speeds up transpiration by warming the leaf.
2. Temperature
Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises. At 30°C, a leaf may transpire three times as fast as it does at 20°C.
3. Humidity
The rate of diffusion of any substance increases as the difference in concentration of the substances in the two regions increases.When the surrounding air is dry, diffusion of water out of the leaf goes on more rapidly.
4. Wind
When there is no breeze, the air surrounding a leaf becomes increasingly humid thus reducing the rate of transpiration. When a breeze is present, the humid air is carried away and replaced by drier air.
5. Soil water
A plant cannot continue to transpire rapidly if its water loss is not made up by replacement from the soil. When absorption of water by the roots fails to keep up with the rate of transpiration, loss of turgor occurs, and the stomata close. This immediately reduces the rate of transpiration (as well as of photosynthesis). If the loss of turgor extends to the rest of the leaf and stem, the plant wilts. The volume of water lost in transpiration can be very high. It has been estimated that over the growing season, one acre of corn plants may transpire 400,000 gallons of water. As liquid water, this would cover the field with a lake 15 inches deep. An acre of forest probably does even better.

This is what I believe is happening here. just my 2cents worth.

Ok here is what i have seen, average temp in the peak of day is 84 degrees with humidity at around 50%, but what i have noticed is that when the lights are shut off that the humidity jumps up to 75-80 % which cant be good, so just today i went out and got a dehumidifier, I think the pilot light from the co2 burner is creating alot of humidity
