I grew outdoor for the first time last year, and did fairly well, so I figured Id try growing indoors. But dont think my plants are doing good. please help. They are about 4 weeks into flowering. the flowers look small, and one of the plants the leaves are yellowing. the one plant always looked small, and the final plant looks the best out of the three, help and tell me what i can do. I will post pic as soon as I can figure out how to. With being a new member I am maxed out on my first day, I have 2 300 watt light, and feed them organic. I am on the 12/12. The bad looking plant is strawberry Kush, and the goodlooking plant and the stubby one is caboose. Fans are running, and the ph is normally right around 7. Growing in my basement, with heat. no co2 system. Temp around 68

I have seen this soooo many times
Nutrient Burn
Nutrient Burn causes leaf tips to appear yellow or burnt. They can also be brown and twisted and crispy looking. Depending on the severity it can show many different symptoms and shows on lower part of the plant when its young, at older stages it can move anywhere on the plant.
Fix Nut
Any nutrient system designed for plants like a tomato will also work in a pinch. Also make sure you are feeding nutrients for the right growth stage - for example, all cannabis nutrient systems have you feed different nutrients for the vegetative and flowering stage. If you are feeding the wrong type of nutrients for the stage your plant is in, that is an easy way to give your plants lots of nutrient problems including nutrient burn.
If you are using the wrong type of nutrients for a plant like cannabis, you will eventually run into nutrient problems, one way or another.To fix the problem when you have Nutrient burn, you want to flush out the plants with lots of water.
Soil
Soil should be flushed with lots of water, Use 3 gallons of water per one gallon of soil. Flush very thoroughly, after plant recovers usually after a week, you can resume using nutrients after a week or a week 1/2. When you flush your soil, you flush everything out, a lot of nutrients go with it, including the soil nutrients.

I flushed the one plant that is yellowed. I fed the other two the same way and they look ok. Why is this? cause of the different strains? There is hope for saving the yellowed plant and flowers now that its flushed? Sorry it took me so long to answer back, I was limited on my post being a new member, and I had to work today. Thank you and everyone for there help
That is because you had a toxic salt build up in your soil, now its rinsed out and your ladies know it, their gonna take flight.
Good to see you back on track happy growings @Larry815
