Bagseed/ Necrosis? Yellow? Droopy?

Hey, I found these pictures online....If they happened to be mine, what would I do to take care of the obvious problems?

Three Plants, the first has serious Necrosis of the tips of larger leaves with yellowing and drooping, all these symptoms have increased over time....Possible mg deficiency??

Then there are a few clips of the set up, CFL closet, three plants fit comfortably in there.

Second clip shows the best plant, though it does experience similar symptoms to a significantly lesser degree.

The third plant, .
It is constantly droopy, the lower fan leaves are yellowing with slighter necrosis, these same leaves also experience a sort of twisting.....

How often are you watering. What kind of nutes and soil are you using? What are the temps in their box. When mine have had yellow leaves starting from the bottom I gave them a higher dosage of vegetative nutes. And since yours are very droopy lookin, could be over watering. Looks like you have a nice little indica growin there.

Unfortunately these are grown in Jiffy soil, using the Grow Big Liquid solution from Fox Farms. The funny thing about Jiffy Soil is they don't tell you the levels ect of the nutrients in the soil.

As for watering I try to water once each plant has dry soil, using distilled water. And once every two weeks I give them nutrients.

As for the temperatures ect, It is kind of a improvised set up and fluctuates pretty crazily. Just kind of fell into this, but this crazy ailment on the leaves is interesting me, is there something to cure this? bring the leaves back to health? or should I trim them and let the younger and greener leaves underneath grow? Why are the two more droopy and a different colour than the strong healthy one?

You should probably be using nutrients more often in the watering, at least once a week. I water when the dirt is pretty dry an inch deep. I water every 3 days it seems, flushing with plain water every 3rd watering. They seem to love it. As for the 2 being affected while the healthy one looks fine? Maybe it just hasn't affected the healthy one yet. I would try feeding them more often.

yeah it looks like the yellowing is actually coming from the middle of the plant, rather than from the bottom. interesting...

anyone else?

Awesome! I appreciate the advice

I'm having similar problems with my plant.

bump.

looks like overwatering and in need of some Nitrogen,,,def increase ur feeding to once a week.....

I had this problem a long while back and it turned out my ph was too low when i added nutes to the water.... If that is the problem then 1/2-1 teaspoon of baking soda is all you need per gallon

can low ph still be a problem if he using distilled water?
