Looks like leaves that got wet and burned. If you've started nutes already your probably a little hot. If you haven't, then you probably need some nitrogen.

Yellow leaves
Hi guys, unfortunately because of an emergency I had to leave my 2 babys with some friends for three weeks. At the bottom some yellow leaves and like burning signs. I don't think it's because of over nutrition. They didn't get any for three weeks. Might be not enough nutrient?

Deficienty
Hi. What is it missing? Is it a lack of potassium and phosphorus? or rather due to weather or old age. This is an older leaf from the middle part of the plant

Still to early to tell? Noticed yesterday and have slightly worsened today. Not sure the issue but potentially magnesium? Getting close to top dress also.
Only on 1 of 3 plants so far. On older growth after getting dose of Recharge the other day. Maybe an N problem as I also use 484? Or mag? Using CalMag every other watering in RO at 150ppm as the soil has some cal and mag. Also getting close to top dress time maybe something else?

help! my plant is turning pale. the green color is losing.
the green color is losing. some leaves burn from the tip to the stem of the leaf. Excess fertilizers (because I fertilized the soil) or deficiencies due to few nutrients? I also thought that it can burn with nearby lights, but the ones that burn are far away

3rd week since 12/12 and chlorosis is getting worse !!! Will my crop be crappy ?
Brought EC to 1.6, added 21ml of calmag, had to add 2L of osmosis water because the EC was 1.78. I changed the bad Ph probe and I let it fluctuate between 5.75 and 6. Should I remove the aluminium foil on the pot to let them breathe ? Not sure they are overwatered, I'm desperate

Can anyone tell me what's going on in week 2? I transplanted and each plant seems to be yellowing on the lower leaves. Not very happy. Was dry when I took it out of the dixie cup and watered with 1/4 strength veg nutes and a root stimulator. It seems to be curling in as well.
