Its suposedly normal at week 7, but it might be lack of nitrogen, it may even be one of the reasons why it is so small.

Check your runoff pH. It should be between 6.3 and 6.5. If it's far off do a flush. Problem solved.

Leave's tips color turning yellowCiao a tutti, da 2 giorni ho notato che le punte delle foglie si stanno ingiallendo. Ho pensato di allontanare la luce dalle ragazze, nonostante stia usando una LED (marshydro ts1000). Sapreste dirmi cosa sbaglio? Dovrei agire anche sulla quantità di nutrienti?Leaves. Color - Yellow

My plants are 3 years old (counting from soaking the seeds) and they are growing really fast but the leaves are a little bit yellowish in the middle. Is this some kind of deficiency or maybe something else? I’m a newbie to this and need your help guys ;)Leaves. Color - Yellow

Why is one leaf yellow AND shiny?Plant has one leaf that is yellow on one side, and shiny/dark and curling up on the other side? From what I've read those are 2 opposing issues (light burn or nitrogen deficiency/or toxicity) the others are pretty much uniform, Could this be from getting water droplets on leaves?Week 3
