What’s wrong with one of my plants?! Help! (First time grow)

Hello all,
This is my first post and first grow, one of my plants seems to be struggling and I’m not sure what the deficiency is? Light bleach? My other plants seem healthy, any help would be great!
first 2 pics are the problem plant.
Next 2 are my other healthy (I think ) plants
Temps : steady 75 f with 65 rh
Viparspectra 600 turned down a lot due to the small grow space. (I only recently turned down the light and the plants seemed to respond well)
Feeding: pure blend pro botanicare
I should add that I transplanted them to the 5 gal fabric pots probably alittle over a week ago. The leaves weren’t this yellow before transplant but the plants were a lot under a weaker light in the beginning,
Thanks again all

No need to transplant.. they look incredibly small but healthy and viable.
Deficiency seems to be the culprit.
I suggest adding cal/mag @ 25% dosage.
Cal-Mag is a very strong nutrient in terms of PPM and will really burn a plant so I always keep the rule of thumb less is more, since you can always add more as needed.

Light burn shouldn’t be an issue keep the LED 18-24” away.
but I assume since they are younger you may want to do 26-34” until they can acclimate better to there environment.

I suggest that you add beneficial to support healthier stronger bushier roots.

Different species of beneficial soil organisms that can colonize plant roots and expand into the surrounding soil greatly increase the absorptive surface area of root systems.
Mycorrhizal fungi, Trichoderma and a diverse mix of bacterial species work symbiotically to promote improved soil structure and enhanced root growth.
Recommended for establishing biological diversity in the root zones.

Hey, thanks for the response, ahhh I see. I figured it was just a deficiency. I will maybe try adding calmag in the feed over next few weeks! what would be a good root booster? Is it really necessary?

Soil normally has some pretty good beneficial bacteria and fungi already added to them.
That’s what makes soil easier for beginners as well as it helps buffers PH discrepancies (to a point).

I’d say go to your local hydro store check out the beneficial they have available.
I use botanicare hydroguard( this is a must)
hydroguard Decomposes organic material and converts it into nutrients that can be absorbed directly into the plant or by other bacteria and fungi.


I use voodoo juice, piranha and tarantula first two weeks of veg and first two weeks of flower.

but if you want to save some cash look at the ingredients on the back of voodoo juice, piranha and tarantula and compare it to other brands at your local shop.

more love you put into it the more love you’ll get out.
just like anything else you got a hobbie in.
