nute burn

hi not sure if ive burned my plants with nutes or the leaves aint gettin the light?will this harm them or my yeild?plz help

can any1 help plz?

How many weeks into flower are you?
That looks like normal bottom leaf die-off during flower.

looks to me like watering and/or maybe a ph problem. do you have a ph meter? how often are you watering/how do you check if they need water?

usually if you overfert the leaf tips will turn brown, but it looks liek yours are turning yellow then drying out so I dont think its overferting. It is also normal for the bottom leaves to start yellowing and falling off as your plants pull the nitrogen out of em mid-late flower. However, it looks like you are more on the early side of flowering, so Im leaning towards ph being off, thus locking out nutrients. That or it could just be youre watering schedule needs tweaking.

My Aurora Indica looked very similar to your plants in terms of the problems, and my ph was way high and I also overwatered. Ive also heard that a high ph will keep your plant from drinking thus causing overwatering if in soil.

My advice would be flush em with some ph'd water.

im 5 weeks monday.i normally water every 2 to 3 days lettin the soil dry.usin the bio canna soil dont need 2 ph it.thanks maybe i shud ph my water didnt have these probs wen i done the church on my first grow,but then again its only yellowin on lower leafs

I'd say your lower leaf necrosis looks fine and normal, but without any pics of the upper half of the plants it's hard to tell the full scope of the issue.

Always PH your water before giving to plants, no matter what soil your using.

I would give em a couple rounds of N while you're halfway through if they're yellowing this much already, and PH the water first.
