IloveLEDstarted grow question 4 years ago
Hello there. I have, as you can see a bit of an issue regarding my plant. What is this? As you might see, the lower leaves seems ok, and that concerns me even more. I have flushed her properly and then gave her adequate amounts of feeding. At first I thought it was lack of P.

Looks like a phosphorus deficiency. I would check run off ph with a calibrated tool first. Also seeing possible magnesium deficiency. I imagine the ph is out of range in your substrate. Hope that helps and is your issue. Good luck and happy growing 🌱🌱

Nutrient deficiency? If yes, what's the best course of action to salvage the situation?First time grower of 3 autos, at week 8, lower leaves started turning yellow, top leaves started to get smaller/develop brown spots 2 weeks ago. Is this a nutrient deficiency problem? Soil should have been fertilized for 3 months, but I'm thinking they burned through it.
