I am a rookie, so please take that into account.

I think you could hit them with some 1/4 strength nutes as you have a few nodes of growth.

Looks like they are a bit hungry to me.

Peace and Great Grows

I agree with asmallvoice they look hungry to me, plus maybe need some cal-mag the leaves are yellow on the ends on one for sure.

Yellowing leaves usually indicates a need for nitrogen unless your late into flowering then its acceptable. Purple stalk indicates a magnesium need(I think) or its a calcium need. If your nutes are present then your plant has an uptake problem.

If its a Ph problem here's a cheap and easy fix. Next time you water do so with no nutes. Just add a cap of white vinegar to each gallon of water. That should lower it to around 6.3 if you're using tap water. If its well water then the amount of vinegar used will be different.

Yee agree with the rest start giving nutes I give them nutes wen there 1 inch big and they start taking off. Make sure you use much less then what they say on bottle. On mine it says 40ml per 10L I put in 10ml per 10L whilst there young
