Nitrogen deficiency. Classic. R u feeding?

 

[JDGreen]

Starting from the lower leaves and progressing up?

 

[Beccie]

Bottem leaves up

 

[JDGreen]

Yes. Typical nitrogen deficiency will jave yellowing leaves starting at the bottom then the yellowing will progress up the plant getting to.more leaves if not addressed

 

[JDGreen]

The leaves will eventually die if affected and damaged leaves will not be saved. But if this sounds like wat u have...post pics....then ur system is lacking nitrogen.

Yes. If thats a seedling dont feed. But if its a clone pleasr feed lol, it looks alittle overwatered, common mistake, and if irs a seedling it may handle a 1/4 fees solution. Ive used that with really small seedling in mostly perlite. But it looks like nito deficiency but.the plant is awful young so its prolly ur medium and u likely over watered and possibly flushed it...any runoff?

 

[JDGreen]

Looks alittle iron deficient too. The lught coloring on the tip. I 1/4 solution feed. Like 1/4 tsp per gallon of some grow solution.

Back off the water. It needs to dry out. The pH swings as soil dries. The plant uptakes different elements at different pH ranges.

Agree, and salts will rise as soil drys. Ph isnt as big a player in soil as in hydro of course but yes i agree so much water, ud be surprised how dru it can get. Pretty much bone dry. With a pot that small, if u brush away some of the top soil and its still damp. Its too wet. About a knuckle down should b dry, in a 1-5 gallon shoot for two knuckles dry. Otherwise its definitely a savable seedling .dont worry just try to get a consistent schedule and environment. This is key to successful growing
