Plant problems

Can anyone help me diagnose my plant problems and ideas on how to cure the problems.

nute burn or overwatering

Hey dogestyle4 man looks like nute burn or maybe you have to much heat from your lights whats your average temp?? try cutting down on the heat or if you cant tryto use a better exhaust and intake fan.Also what your watering schedule like if you know your not over watering them then try the heat and if not could be the nute burn in that case flush them with alot of water.. Keep us updated

I don't see anything wrong with your plant. Its natural for a plant to draw mobile nutrients from the lower leaf when your feed changes.

If Hydro, Flush 48 hours then back off the nutes until you see it getting greener.
Remove the dying leaf and move on.

my current setup is 3x4x7,400 watt hps,vortec 4" 172 inline.plant tops are 25" from light.in the summer, temp stays around 80 f with the light on. 3 plants were flushed and transplanted 1 week ago.plant a is grown in hp pro mix with the techniflora feeding schedule.this time after flushing i fed 1/2 strength.plants b and c were grown in 1pt worm castings,1pt perlite,1 pt ocean forest. b and c are fed indo and mex guano and soluable seaweed.after transplant and flush to b and c.the same soil mix was used exept dolomite lime,epson salt,and mychorrhizae,and a little guano was used in the mix..since our city water is over 8 i have had ph problems in the past.now i use rain water and keep the ph around 6.5.would city water 8 ph be better than rain water if it is ph ed down.hopefully the new pics will show problems better.any thoughts or ideas would be helpful.also can i flower in these conditions.also for organic what is good micro nutes.this time around i added supernatural green + stay.seems to have good micro nutes.anybody know anything about green stay.

cough cough cough

are you spraying your leaves while the lights are on that was my prroblem and it has subsided so i reccomened yuo try to spray them a lil after light s go off for sure not nute burn might be shocked from transplantin should be okay keep an eye on ph from fluctuating to much good luck and happy growing

Rain water would be much better then tap because you never know whats in tap.
Sure you could adjust the Ph in tap, let it sit uncovered for a while to dissipate the chlorine, I have done it. But after switching to r/o water it was light night and day for me. Plants responded right away.

Sorry, I don't know much about soil nutrients.
