If you look at the true LEAF TIPS you will notice no burn. The edges are showing deficiency ( I am guessing magnesium). You haven’t burnt your plant.

Yellow tips of leafs …Overfeeding? Yellow tips starting on top of the plant … should flush or just wait and reduce the feeding next watering? I‘m entering the pre-flowering stage and would normally start to add bio bloom and top max with the next watering …

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

What could this be?What could this be? It's NL auto with a hydro set up in the transition phase. I believe it had nitrogen lock prior due to over feeding nutrients. I cut all the old leaves that had this and it keeps happening to leaves that we're healthy. Was much darker green and looks better now

All of my plants have started to burn yellow in colour when they switched to flower, they have also lost they lovely green colour and started to go lime. Too much nitrogren still in the soil? Or Just a deficiency? They have recently been fed 1ML fishmix and 2ML Bloom.
