Brown new leafs...

Heyu,
Ive got problem with one of my plants. Its NYC Diesel. Its growing up but a lil bit too slowly. Ive got three other plant and they are doing well. Plants have 7 days and Im growing them under 250 HPS with diamond reflector in DR80. I keep temperature 27-29 degrees Celsius at day and around 21 at night. PH 5.9- 6.0. Moisture 45 - 55%. Medium is mix of Bat-Mix from plagron and All Mix from BioBizz on scale 5:2. I started feeding them with rihzotonic from canna.Second feeding was with rihzotonic and canna terra veg with more less than half strenght - 2ml per litr. Last feeding was with cannazyme as well a lil bit too. I used to spray them a bit but stoped doing that because i thougth that this could be a problem but like you will be able to see in the picture new leafs are growing brown as well.. Help me guys kiss-ass



And here are my other ladies.From left blueberry from DP, Arjans UH 2 and SLH both from Green house seed lol

Come on guys im sure one of ya knows answer...

I could be way off here so dont take it the wrong way, but it looks like possibly they aren't happy with the food they're getting. Mine usually dont take too well to any kind of nutes at the early stage of growth, but all plants are different, some need nutes earlier/later than others. Defnitely not normal whatever it is, i'd check PH like DOC says there and maybe flush with some fresh RO water. Just throwin in my 2 cents, goodluck with the grow!

Thanks for answers. I think my PH is ok, rest plants are growing very well and fast. Here you have picture after just one day.



Im willing to think that maybe NYC doesnt like nuts at early stage... but on the other hand amount of nuts was very little. I can give you one more hint. Leaves balloones in the middle and brown color occure only in the middle of plant. It gets green while leafs are getting older U no what i mean? Here are pics.

Heya folks I flushed every plant and NYC is getting better. Never feed your plant in first 2 weeks(except rihzotonic) if you have good quality medium. Take it easy guys xxx
