Hey,
Just by the pictures, I'm guessing your ph is a little low. This will cause calcium, magnesium, zinc, and iron to be locked out. Make sure you're measuring the ph of your runoff water. Pm me if you have questions.
Cheers,

It could be a lot of things, without any info on what they are being fed/how much/how often/ temp/ humidity/ etc. its harder to make an accurate diagnosis.

Yellow Leaves AutoflowerNovice grower, Outdoor. Started in a 70/30 coco-coir to perlite mix. Forgot Worm Castings until 22nd June, implemented with top dressing of Gaia Green Power Bloom and All Purpose. Overwatered at stem for a week or so. I suspect it's either an N, P ,or K deficiency (nuteburn?)

Yellow Leaf Tips with Brown Spots – What Could This Be?One of my plants has yellowing tips on some of its leaves, and there are also brown spots forming on these yellow areas.
Any ideas on what could be causing this? Could it be a nutrient issue, or is it maybe related to pests or environmental factors?

Triple-leaf Speedy Chile: what is growing there? Why becoming yellow?My triple-leaf Speedy Chile (see also week comment for more info): 1. The 3 cotyledons have become yellow. I also see on lower leaves slightly some yellow tips. Nutrient deficiency? Underwatering? 2. What are the small leaves coming out of soil. Another plant? Should I remove?
