These 2 are in the same room same amount of time given the same amount of nutrients. One’s turning out exactly what I need it to be and the other is not producing as much and color is way off :/ what can this be from if they are given same everything. Problem during veg? Any input helps thanks y’all

That's so weird I dunno why one would be different like that

Are they from same mother plant?

Yes. The redish leaves started happening end of Week 5. In 2 days it’ll be 7 weeks into flower

Kind of looks like P. Are the stems purple?

Yea most of the stems are purple I noticed they are stressed to. Best to leave it like this until chop? I go week 7 this Thursday.

That one plant is very underdeveloped. It depends what you plan to do with your grow space after chopping. If nothing much is coming up, you might want to figure out the problem (pH, too much Ca, not enough P, whatever) and grow it out.

Thanks for your input. There is about 20-25 underdeveloped plants out of the 270+ total. Is it possible it’s just from the plant?

There is nothing wrong with that... the plants is not photosynthesizing as much and anthocyanans are starting to show. This can be for many reasons, genetics, a bit to much light, lower nitrogen feeds and PK boosts (basically anything that reduces nitrogen uptake) cooler tenps will start to make the colors pop even more.

Eg.second pic is after this has started for a week or 2 and first pic is at harvest.

I really figure it’s the genetics because like I said there’s about 25/275 that are looking underdeveloped like this. If it was from the lights, or nutrients , etc I feel like way more would be looking like this but the rest are as big as the good picture. Thanks for
The input !

Look into senescence in cannabis... absolutely it will be genetic but there are things you can do that will bring the expressions out quicker and more prevalent.

Id plop some yellow sticky cards on the surface of the pots the bad plants are in, just to rule out that you dont have root pests. Maybe even pull a root ball out and inspect it.
