Deficiency issue...

Hey guys, this is my first thread so I'll try and give all appropriate information.

I've done 3 hydro grows prior. This is my first soil grow. So far it's been going well. Ran into some nute burns and a nitrogen deficiency early on but took my time, flushed, and was more gradual with nutrient changes.

I've got two plants (Kush and Cheese) in 5 gallon buckets, 4 weeks into flowering. Running a 600w HPS (MH during veg) with good ventilation holding around 85*F. Using Pro-Mix soil through the entire grow - the HP variant that has Mycorrhizae. Watering with PH corrected tap water that sits uncovered for 1 week before using. Currently feeding with GH Nutrients via Lucas Formula. Have been watering on a Nutrient-Nutrient-Plain schedule at 75% strength of the Lucas formula for flowering.

I LST'd both plants about two weeks ago due to height restrictions... primarily because of the Kush plant, it's simply massive.

Anyway, the Cheese plant is tiny in comparison, but has been moving along nice and steady. However, I've noticed slight browning in the leaves. It seems to be very gradual and hasn't been showing throughout the whole plant. Seems as if it started on the main fan leaves towards the top of the plant and slowly is popping up elsewhere. It is not on any lower foliage. This plant is due for watering probably tomorrow and will be watered with plain water (since I watered with nutrients twice before this watering).

Note: I was planning on introducing a small amount of GH KoolBloom (2.5ml per 1 gallon) since I'm at 4 weeks of flowering to be cycled through only during the plain PH'd waterings - not mixed with the other nutrient feedings.

Let me know what you guys think, I've been pretty good at searching around and figuring things out on my own, but I'm just not 100% sure on this one. Though, I must say, overall the plants have been doing simply amazing and I'm really enjoying growing in soil for the first time and doubt I'll go back to hydro. Cheers!

This is the Kush plant in the front. If I wouldn't have tied this thing back it would probably be standing 6ft by now.

Look's like to much of something I would feed/water/feed/water using a ppm meter and a feeding chart that increasing the ppm gradually till you reach your max of 1200-1400 plant that size 1200 ppm, dirt growers usually feed every other watering~

Thank you for the advice. I'll switch to feeding every other watering. I don't necessarily see it getting worse (since I watered on Friday evening). I do have a few fan leaves that are losing color and look like they'll be dropping off soon though. I'm hoping this was due to whatever the root cause here was.

Do you have any recommendations on a PPM meter? I always see sooo many differing opinions on anything under $100.
