One veg plant out of bunch stopped growing

Hello and thank you,

I am growing some Phantoms [cherry pie x GDP] from Harborside and they have been in 1 gallons for 10 days now. They are under 6 T5 6500k lights in a Quantum Badboy lighting system. Feeding them a Flora Duo A+B regime, though have only given them this once and only the A, along with General Hydro BioRoot, BioWeed and BioMarine. They are all looking real healthy except for two, which havent grown at all in 5 days, while the others have, as you will see, doubled in size.

I am not sure why, my idea was bad phenotypes? Thank you for any help

I don't know what you're idea of "healthy" is but they all look pretty deficient to me. A couple different deficiencies at that. What is your pH?

I agree with rockstar energy they dont look to healthy. How often do you water them and how much? If you are watering the small ones the same amount as the larger then they will always stay small with very slow growth if not root rot. You need to remember wet roots through veg equals lazy roots then them dry out to about a quarter of the weight they are at when watered this will force the roots to stretch then feed small amounts until the root base is established. Is a common problem people hit at the first stage one over water and it can take a while to finally get going. Hope this helps mate.

It might be overwatering. Also there are some deficienies for durr. Try a good light mix (light in nutes)
soil. Also,try to water when the leaves slightly point down. Its much more accurate and u will never
overwater again. Test your water ph and your soil ph as well. Find what makes them sad

/\ what are you guys smoking?
Those tops, and new growth look really-really good... So, what ever happened one week to week and a half ago [it looks like u fixed it]?
The bottom leaves are yellowing, but I do not see that as an issue with a new growing beautiful plants...
If top leaves have color changes then worry, in those pix...tops look beautiful...
Now to answer your original question: Some plants will just grow slower...
Make sure you let the plants dry a bit between water-ings....
Good Luck!

Haha thought id found a forum without the little idiots putting things like "what are you guys smoking" but guess you cant avoid them all. were here to help and pick up tips along the way Not to try and put people down if you actually know what your talking sbout then explain things.
Anyway i had another read of what you put i work in the hydroponic industry myself in the uk and just wondered why are you not using the B part of flora duo, im not familiar with this range i would always use a+b thats why they are sold together and not as singles not saying this is the problem with the two that are not growing im still going to say overwatering if you get chance reply back with how much you water them and the ec/cf and ph. Also run off ec/cf would be a bonus.
Also if you plants have been done from cuttings of the same plant then they should never grow faster than another one not unless ther is a problem so dont just sit back and hope it solves itself get to the bottom of the problem asap.

Yeaaaaaaaaaah but most issues start at the lower leaves and work their way up the plant.
