What do you all think this is?

[Bucsfan80]

Just noticed this and am wondering what it is and what caused it. The last pic is zoomed in some. I have my suspicions but just want to confirm with you guys and gals.
4ish maybe 5 weeks, dwc, tap water @50ppm GH flora trio. 5.7-6.0 ph. Running just under 500ppm/1.0- EC. Topped once and lst'd. Roots are long as hell and look and smell fresh.

P def?

P def?

I'm not sure. It looks different than other posts about p deficiency I seen.

I have a sherb cross that does that naturally, but not sure in your case. any signs that the plants are unhappy?

What's your temps?

What's your temps?

Lights on 77°-80°. RH% try to keep it low to mid 60%. Lights off 70°

I'd wager either a touch of p... or just the genes....Looks pretty happy? Can't say I have much experience in deep water culture tho....Do you find it easier than soil? I just start two more autos in soil... but this dwc looks interesting.

What do you think about light/heat stress? I had the light pretty close.
I haven't grown soil so can't speak to that. I love it! It can be a little finicky at times but so can anything right.

I mean, I run a bar style and I was at 18" veg ...then 14....then 12" in full flower, but i know the qb boards have a hotter center light wise....I mean it COULD be, but the ts1000 is a pretty easy going light imo...either way id back it off a few inches... they dont need much in veg...And you'll know soon enough.... Kelp has turned many a P deficiencies around for me, easy to use and water in.. and its hard to over kelp if you just follow the directed mixing.

Anything is as easy as you make it on yourself.

Could be genetic.

possible sulfur deficiency...or possibly natural coloration...

Could be genetic.

Anyone familiar with GG#4 that's what it is.

 

[HydroKid239]

If it was me seeing this on my plant in week 4-5ish of veg.. I would bump feed up to 700-800ppm.

there's no being familiar with a certain strain anymore, every seed bank has a strain from a different breeder, and not a single fucking one of them are the same as another...i have 3 different versions of gorilla glue 4, one from the vault, one from Pev, and one from seedsman(where they have 3 strains called gorilla glue that look nothing alike at all)....and they look, smell, grow nothing alike....

seconded, Id bump it up to somewhere around 700-750 and see how that shakes out
