More Leaf Problems (Pics)

Hi all!

Out of my 12 plants most of them look healthy but I'm still having some strange leaf problems?? I have yellow tips on some, and others are just crispy and curly. The temp in my room is a little high but not out of hand. Does anyone have any idea what may be wrong? Over or under watering or too many nutes?? Any help is greatly appreciated!!

Thanks!!!

Looks like nute burn. Flush the soil.

Phosphorus toxicity. Leech soil. Recalculate your nutes phosphorus level too high for those plants. Good Luck.

I've been using Fox Farm at 3/4 strength. I'll try a flush tomorrow and see if that helps.

Thanks~

I use fox farm products @ 1/2 strength. Are you using open sesame, beastie bloomz, and cha ching as well. If so those products have huge phosphorus numbers.

How do I properly leach my plants? I've never had to do it before. Do I just flood them with pure water?

Again - Thanks!!

Yes. Water until at least a gallon comes out of the bottom.

Looks like nutrient burn.
