Flowerng questions

[Jring15]

I have an unknown strain, that I have been flowering for about 3.5 weeks, without any type of nutrients. I am using a bubbleponic system and recently I have noticed that the bottom rows of fan leaves are gradually yellowing and dying off. Is this because the plant wants more light to the lower buds? To be more efficient? And how much do you water it/spray with mister? Please help

Best to have you fill-out the troubleshooting form, as we'll be shooting in the dark with a diagnosis based on limited info. There's a link in my signature, scroll down to the Hydro Form. Copy-n-paste it here, and answer the questions.
-But-
Flowering plants need nutrients.
They need proper lighting. (proper lighting that can effectively extend to the lower regions)
And an overly humid enviornment (including misting) promotes mold. Moisture get's trapped between the tightly-packed budleafs.

Check the site FAQ's, and perhaps a few Grow Logs and the Hydro section, to get a better idea of what other's are doing for success.

Although yellowing fans is normal in late-stage flowering, 3.5 weeks in is a bit early for this in most strains. It's likely due to nutrients deficiency and/or lighting.

So eventhough I haven't used any nuteriants through the whole process, you don't think that it would be bad to introduce a new substance "nutrients" to it while it is this far along?

I'm suprised it is still alive.

[Jring15]

It's surprisingly going good and buding nicely, just the fan leaves are yellowing

[Rusty-Axe]

No it wil not hurt the plant to introduce it to food. :wtf:

[Jring15]

What would be the best nuets to use? And have you ever experienced adding nuts to it this far along? Because I don't want it to die On me. So should I not spray the plant while in the flowering stage at all?

Yellowing of fan leaves and eventual dropping is usually a normal response during flowering. As was mentioned, avoid high humidity/misting.

Try making a tea 4/watering using 1 quart of warm water and 1 teaspoon of molasses(the sulfur free type you buy in grocery stores)...works well for me during flowering.

And...fill out that form when you have some time w/pics...rusty t. here is very good and has more patience than I.

[Rusty Trichome]

Your ph is too high for a hydro grow, you need to feed 'em, and likely a good idea to refrain from spraying them. But most importantly...do some research if you plan on success. Most all of this is covered in the FAQ section.

Banana's? :wtf:
