hey guys One of my 3 35 day old mazar plants has yellowing leaves, and some leaves are beginning to brown and die! They are in 9L pots of potting mix with perlite and some blood and bone, under 600w HPS, average temp of 26 degrees, rh of 36%. They are being fed with worm piss, seaweed extract, fish emolsion and some multigrow. I first realised there was a problem yesterday when it began to yellow, i then flushed them, but now the leaves are burning! Here are some pics, any help would be great!

my plants are taking a turn for the worst i dont know what the problem is if tryed epson salt nuts all kinds of shit i really dont want it to die any help please.

I have some white widow plants that were doing fine and then i gave them a weak foliar feeding of miracle grow and they for the most part stopped growing verticle. they continued to fill a bit but its been about 10 days and still only verticle about an inch. they are now about 12-14 in tall, real green and healthy looking but not growing. I water them when the top of the soil gets dry but before they wilt. the ph is around 6.8 as of today. the temp is in the 80's and light is on for 18hrs. i scotts potting soil which had nutrients already in the soil, mixed with an organic potting soil. i just added some calcium because i saw that a deficiency would stunt growth,…

I dont know what im doing wrong, so im going to have to tell you guys everything so sorry for the long read. I am growing in a grow tent in the wardrobe, in nutrifields COCO (50% perlite from bunnings) using nutrifield nutes part A and B. I have a 400 W HPS that is sitting 22 inces above my plants (they get about 500-800 LMS, have tried closer but that just leads to burning), air conditioner on the outside of the ten…
