help please

Not sure why my plants are yellowing out. They are clones yet different strains. My from seed plants arent doing this.
Ffof soil. Recently up potted about a week ago. Just tap water except a drop of dyna grow every now and again. And i spray with neem before nightfall a couple times a week.

Some more shots. You can see the clones aren't as happy as the from seed plants

they're not bad. i'd give them some veg nutes for the extra nitrogen. a soil and foliar application of Epsom salts would green them up nicely.

I agree looks like they could use some veg nutes. For foliar I recommend some form of RAW nitrogen, this is amoniacal nitrogen and will not burn your plants. plants only take in what they can use of amoniacal nitrogen where nitrate nitrogen can burn.

I don't think giving them a little Humic Acid and Kelp would hurt either... all the plant growth hormones in the kelp would help bring everything around.

You sure they need nutes?

looks like nitrogen deficiency to me... or it got over watered at some point, but looks nice and dry in your pic...?

This ffof soil holds water like crazy. The top dries fast tge bottom doesnt tho.
Even with neem sprayings i cant seem to ditch the thrips and white flies. Also these tiny green grasshopper lookin things.

i would say that's your issue... water logged soil will produce a similar look to nitrogen deficiency.

that would also account for the thrips and flies, their larvae like those kind of conditions.

you could transplant into a mix that has more perlite?

my bro just used something called promis aphid, thrip and white fly killer? worked good for him
