seems like a little bit nute burn.but dont take me that serious ım just a noob

no. real nute burn is shown as dark dark leaves, blackend tips and such.

its a slight nutrient burn i wouldnt worry about it.if your using slow release or organic pellets i would try water as little as u can without starving your plants.the more u water the faster your fertiliser breaks down and feeds the plant.

o i c it now. yea its there.

I bet you thought you could just follow some online nutrient feeding chart and be done with it. Not quiet that easy huh. Overall your doing great. Your watching the plant and you didn't over do it. keep listening to your plant, skip a feeding, and water like normal.

The medium is an organic mixture formulated by a commercial grower. I really don't know what's in it specifically but it works for my other plant.

The medium is a pre nuted organic mixture from a commercial grower and truth be told I don't know what's in it. I've been using ph water of around 6.8 . I saw someone else s plant that looked kike it had similar problems and you diagnosed nute burn and I think your right on with mine as well thank you.

Nute burn.

Whatever you do, do not flush. Will cause fert to break down more and burn more

Thank you all for your input the consensus is nute burn so I'll back off on the watering as the medium is pre nuted. Again thank you all.
