Unknown Plant Deficiency

Growers, This fine ladies shows some symptoms and would appreciate your help in figuring the problem out.

The larger plant is 3 weeks old and is watered with PHed water with half strength BioBizz BioGrow nutes every 3-5 days in quantities of a few hundred millilitres in a 2 gallon pot.

It's growing in BioBizz Light Mix and is under 50W of CFL lightning.

What's your take on the reason for the light green colour on new growth?

Let us start with. Should be in separate pots, increase lighting, Stop over watering. That be my opinion.

Agreed (yet again).. That plant looks in decent enough soil.. there is NO WAY it is having a deficiency by default.. It probably can't uptake because it is 'drowning'.. That said, they look like you could separate them at this stage easy enough, perfect time to get your watering down too..

They are not separate due to lack of space. The taller plant is probably going to be removed.

Soil is wet just because they've been watered yesterday. Otherwise I let them dry really well before they receive a couple hundred millilitres of water.

i dont think the plants being in the same container is causing this however, it is not good and should be seperated soon before they become tangled and you cannot. as for whats going on here...its def looks like an uptake problem IE. ph is off or maybe something else that is causing lockout. it looks like its not getting the amount of N it needs, as well as some other nutrients, i would try to figure out your PH and make sure your feeding, and if you are, it doesnt mean to add more, that is not the problem necessarily...what seems like is happening here is your plant is in a medium that the ph is either to high or to low, which in turn causes what is called ''lockout'' where your plant and its roots cannot uptake the nutrients your giving it because the ph is incorrect. THIS IS ONLY A GUESS of whats wrong from one picture, i could easily be wrong, do not count my word as gospel, its just my humble opinion. good luck

well i dont think you should be giving water with ph of 7 depending on what you have in your soil its 6.5 or bust. if your soil is ammended well it shouldnt matter.

Those plants are too small to need fertilizer esp in soil.

I wouldn't sweat the pH thing in soil. Unless it is crazy off the charts, it is often more harmful to try to chase "perfect" pH with flushing, pH up. pH down etc. The soil will buffer solutions to get them in the range that the plants can use.

What is your water source? Is it tap water? Do you know the contents of the water (ppm/EC?)

Did you soil come amended with nutrients, organic or otherwise?

Were the plants showing deficiencies? Why did you decide to start feeding them so early?

Thanks for the feedback on pH.

It is tap water. I do not know ppm or EC.

It's "light" soil so it is supposed to be nutes free. I'm using Biobizz Light mix.

The plants did not show any deficiencies. I fed them lightly because I assumed a nutes-free soil will require some nutrients.

Plant seams to be growing with light yellow leaves.

Problem is lower leaves have slowly started dying.

What to do about this?
