Bottom leaves turning yellow

Your plant is suffering from nitrogen deficiency, A cannabis nitrogen deficiency will cause the older, lower leaves on your plant to turn yellow, wilt away and eventually die 👌🏾 Hope that helps . Much luck to you and you grow 💯

Hello.. Hope you are well.. They are just asking for a small feeding.. U can see clearly the smallest plants are still using the nutrition in soil but all ur larger plants are not shinny green and are at the size of her pot so will av definitely used the goodness in the soil.. Just give them a slight feed or transfer to nxt pots.. Apart from the yellowing which us just leaves used all the energy they look great.. Wen they show sign of new growth u can snip off bottom leaves.. Stay safe n gud luck with your garden.. 👍🍀

Looks like they are due for a transplant and a feeding. Its probably all root inside those little jiffy pots.

hi buddy how high is your ph and ec? what is your watering behavior?

Hi mate, although I do indoors, and soilless it seems like your plants lack of cal mag. But first of all check your the ph when you water and the run off. May be the nutes are locked and not accessible.
