Bottom leaves yellowing and dying

[Reegansmit]

I have 3 plants 2 of the 3 have yellow leaves at the bottom and yellow tips on the end of some of the lower leaves

I've been doing the exact same with all 3 and this one is fine

Looks like nutrient burn to me but I'm still learning too hopefully someone else can answer more definite, what strength or u feeding?

Not sure what you mean by what strength or feeding

How much food or u putting into the water do u test Ur EC levels? Just weird that only one would be burning or they a the same strain?

I've put fertilizer in the soil, I just use straight water and I haven't tested ec levels. I'd say it's probably that though how do I test ec?

I use a blue lab truncheon to test mine however there little pricey if you don't already have one, personally I'd lower the strength of the feed fertilizer your adding to the water, and maybe think about testing your ph levels aswell if your feeding from the tap they might be a little out too which won't help nutrient intake
