Thats not nute burn. Nute burn starts from the tip of the leaves. Check this out!!

That's not very helpful. Nevertheless I remember I mixed in about 100 ml of tap water. It's possible the chlorine messed up something in my solution. I just flushed with a milder strength solution and ph slightly up: 5.9

The cholrine in your tap water is not strong enough to hurt your plants, so thats not it.

Age of the plant and the strain? You say a full strength feed - have you fed them before and if so what was the strength of those feeds? What medium are the growing in?

I kinda lost track of time. But it was put to germ on the 7th of October. I'd say 3-4 days later it sprouted.
Medium is 100% perlite hempy bucket. The seed themselves were put in a small rockwool cube and later went into 10cmx10cm rockwool cubes. The total volume of the buckets is 4.5L (about a gallon)
GH 3 part nutrient 0.7 ml per liter of each Micro Gro and Bloom (this is "full veg nutes" according to the schedule). I never felt the need for a EC meter so I don't have one <-- I follow the schedule on the bottles
Base water is 84 ppm.
I've fed them before starting at equal parts 0.2 ml/liter, then 0.5ml/liter and once 0.7 ml/liter and after the second one this happened.
Today I flushed with 0.5ml/liter equal parts solution at 5.9 ph
Might I mention they've been raised up to this point under Bridgelux Vero 18 80 CRI 4000K and have received their second full veg feeding on their first day under HID/MH. I noticed the deformity today on the second day
Hope it helps

So any idea of the actual EC of the feed?

no idea mate.
There is a development: on one of my slightly older plant there is a little indication of either phosphorus or calcium deficiency. The feeding schedule has never steered me wrong and I'm pretty much dialed in at that department. It's possible that I might have gotten a wrong PH reading due to haste. Either way I'm ready for another flush and if things evolve I will get back here tomorrow

I asked because another [person here might have experience with that strain and would possibly know. It might be just the pheno you have as well. Good luck.

I know exactly what you're saying. I was considering whether or not the spectrum or intensity of light might affect nutriet uptake or lockout

Alright folks, things have advanced a little more to the point where I can identify my problem with the pics on the internets. It's Phosphorus and quite possibly Potassium deficiency. It's possible I did a mistake somewhere when mixing nutrients. Hope it helps someone in identifying their probs down in line. Cheers y'all for contributing
