indoor grow in tent. Led 600w. Fans & scrubber. 5 plants in 3 gal smart pots. Soil used: fox farm ocean forest. I have the ff trio of nutes and have been feeding every other watering--which is about once/week.

Ph hangs out around 7.

4 different strains.
Leaves have been turning silver. Raised the light but not sure that's my only issue. 4 of 5 plants look strong otherwise. Ideas?
Thanks

Definite heat stress. I believe your leds are too close and you are burning the leaves itself. Id raise it and are it if fixes

I think you're right. Heat stress/burn. I also tested the soil and PH is fine, but other nutes too high. Guess I need to flush the soil.

Are you feeding the soil? Do you have any burned tips from nute burn? Can u please post a picture of your olant w.o led light so I can better diagnose your plant. Heat is definitely am issue atm not sure about your nutrientd. Plants uptake nutrients slower in soils meeda bacteria to break down i dont think flushing is doing any good in a soil medium unless youve made a really toxic environment from adding extra nutruents. Most soils plants can live on 3 weeks t a month before they need food. Sooner if you go into flower as its demands will raise significantly to deal with the changes (growing twice its size)
 
Should Silver and/or burnt tipped leaves be removed? I've gotten myself very confused about pruning, especially since they're all autos.

You dont want to remove heavy amount of leaves its how the plant gets its energy and they can tell which is the biggest and rely more on them. Never remove more than 10 percent of total leaves to prevent stunting. Theres really no point in trimming in veg its more to allow light to the flowers you dont want to trim past 1 week leading into flower it can cause unneccesary stress on the plant. Only remove fan leaves that cover others.
 
The tall one is bb and probably the crispy tips are due to light proximity. The little disaster plant is nl that never budded. It still grows slowly and wimpy. Wait or toss?

You definitely are overnuting, what are you humidities? That upward leaf tip curl is a sign of somethign goin on screwy
 
Reporting back: Did a couple things:

--cut time from nearly 24 on to 18/6.
--Kept an eye on nutes. Still hit them about 1x week-10 days with the FF Tiger and Big Bloom. Though I only nute one gallon and evenly divide that among the 5 plants, then soak them to run-off with pure water. (not sure if that's proper...ideally am I supposed to load all the water with nutes? i could see some burn issues there).
--All plants are doing well.
--The NL I gave up on and as a hail Mary, blasted it with Tiger Bloom...and then it started growing like crazy! It's super lanky and wild, but is FINALLY entering the bloom phase (it's about 1 month behind the others). I'm having to SCROG it because of the amount of branches. Woo hoo!

Still having problems with humidity (70% +/-) Going to try adding an intake fan (currently only have exhaust fan & carbon filter, and 2 small internal fans). Also adding a small pail of Damp Rid unscented. Not sure what the next step is...
