Help me figure out what this is? Picture inside.

So I am about 3 weeks into flower and I have two plants that each had one leaf looking like this. These were both at the very bottom of each plant, so they do not get much light. I am feeding a very low dose of Tiger Bloom every other watering. 1/2 teaspoon instead of recommended 2 teaspoons.

These did not fall off yet, I pulled them off to take pictures, though I didn't have to pull hard at all. I usually give it a little tug and if it doesn't come off I leave it.

pH is 6.7-6.8 when I water via my pH pen. 2 Gal containers/ FFOF soil.

Thank you. I will wait longer in between waterings. Has been every other day or every 2 days. No set schedule really, been trying to water when the pots feel light.

It's P def. Either you aren't feeding enough P or your ph is high. What is the ph of the runoff?

Can you post some pix of the whole plant and some close ups?

I sure can man. I appreciate the help. I have been feeding them a low low dose of TB since they started producing bud sites. The label calls for 1-2 teaspoons per gallon and I am yet to surpass 1/2 teaspoon per gallon.

My pH is always measured going into the pot at 6.6 or 6.7 and the soil is FFOF although the plants have been in the FFOF for over a month at this point and I expect the 2 gallons of FFOF to be used up in each pot. (Pots are 2 gal size). Since I have been monitoring the pH so closely I haven't checked the run off but I imagine it is fine. For me to check the runoff is quite difficult, which is why I have not done it.

So you think its a lack of P? That sounds like it could be plausible since they are at 21 days of 12/12 and starting to bud. I will get you some pictures here soon. Thanks again.

edit: the photos are in order.

1. A leaf that fell off on its own.
2. Bottom of the plant that had the leaf fall off on its own.
3.I have 3 plants total this is another plant
4. And a shot of the LST'd plant in the middle

Looks pretty healthy to me, try feeding every watering at that strength?

Increase the TB to 1 tsp/gal and check that runoff ph. If you are using tap water you may need to lower the ph of your waterings to bring soil ph down, but check the runoff first.

Also, how much light do they get? (watts)
