Phosphorous deficiency in flower?

[firsttimegrower12]

Does this look like phosphorus deficiency to you guys? Its only the very top of the plant that are turning this "lime" green color. Her runoff PPM last water was 775(400PPM going in). Is she under-fed?

A few questions.

What's the pH of fresh feed and run off?

And how far is the light from the top of the lady .

Also. What is the medium. Soil/coco/mix of? Try to gather a bit of info for ya to help get you a good diagnosis

What kind of light - Make and model. Light burn?

IDT that is not enough nutrients.

Sorry...thought I put that in first post...made it right before bed last night lol. I have an HLG 65 Quantum Board over each Fantasmo Express in a 2x4 closet. The other one is beautiful and showing no signs of any problems(knock on wood...lol). The other(the one in the pic), is showing early problem signs tho. They have both been fed the same nutrient mixes and everything so, Idk? Could it because its in a smaller pot, maybe I need to feed it more?

Well 12" to the light is on the edge but since only the top is effected it may be light burn. I think in soil I would be running at least 80% of vendor chart. The entire plant looks a little pale.

Youre right, it is pale. The top leaves look the worst tho. I guess ill try a full strength feeding next time.

There's a fair number of reports that could best describe growing Fantasmo as "worrisome". Mine started to go pale and never really recovered - only plant to have anything like it of the 6. But it still produced 4 oz of good quality flowers, so I've got two more at day 30.
