Nute Burn?

Hi guys first time grower here. I have one Amnesia Haze Auto and two Northern Lights Auto's. Ive noticed on the last two feeding's that my Amnesia Haze has been showing what appears to be signs of nute burn. They are in week 6 since sprouted and the Amnesia Haze is about two weeks into flower. I have been following a water feed water feed every other day schedule. Two feedings ago I used FF Bigbloom @ 15ml's per gallon along with 10ml's Growbig and 1/8th tsp of Open Sesame, obviously less than the feeding schedule . The day after I started noticing some slight nute burn on the Amnesia so I watered like usual 2 days later with just RO water and 3ml calmag. Then 2 days later I did a slight feeding with BB @15ml's and GB @ 5ml's 550ppm. Today the burn seems a little bit worse and I was wondering if I should do a mild flush. PH runoff on all 3 plants has ranged anywhere from 5.8 to 6.2. The Northern lights auto's have been doing great its just the Amnesia that Im having trouble with. Any help is greatly appreciated.

Welcome to growing man! I wouldn’t flush em. Water them a little more maybe, they look thirsty lol.

How far away is your light?

Thanks for the reply King Oberon! I have been super careful on watering so I don't overwater so ill take your advice and step up my watering a bit. The lights were about 7 inches above the tallest plant which does happen to be the Amnesia. Today I lifted them to about 9 inches above. I have the TSL @ 100% could this be light burn? As you can see with the tall Northern Lights plant its almost as tall as the Amnesia and it hasn't shown any symptoms. I have read that Amnesia Haze can be sensitive to nutes and I was thinking maybe that was the issue especially since the other two plants look good. Thanks again for the help.

No worries! I’m no expert bro, I’m still learning
but my thoughts are:

Your light is too close. I usually keep my canopy 18 inches away.

Decreas nutes, increase water, bring the light up, trim them a little and maybe research LST.

You want all those leaves looking up towards the light, not drooping down.

What’s your light cycle?

I would check the soil PH with a slurry. The one on the left looks a little frazzled by PH. They all look a little... yellow(?) to me. I'm sure someone will correct me, but I tend to associate that kind of color with an N deficiency. Wonky PH can cause macros to not be available. Again, I'd do some slurry tests. At least PH and N.

Rapitest by Luster Leaf is my go to.

Good luck!

Thanks guys. Some great advice. My light cycle is 18/6. I test runoff after every watering but i will also try a slurry. King i think your 100% on the watering, I've been underwatering it seems. Its just strange that 2 out of 3 plants are doing well under the same conditions for the most part. I guess every strain acts a little different. Since they seem to be taken a good amount of watering would it be wise to water everyday but switch to water, water, feed and so on?

I know pics help so I've attached some more. Also do you guys think its weird that two Indica's of the same strain can be so different in shape and size lol. The one Northern Lights is short and squatty while the other is way taller.

In my opinion, which has nothing to do with your problem. Why the scrog net, its not doing anything atm. Just getting in your way, will cause you more problems than not having it. This is only my opinion, like buttholes we all have one.

truth!

As you can see I've used it very little lol. Since this was my first grow and I've done a lot of research i planned on doing more LST with the scrog net but I've actually done very little so far. Also with that short Indica unless i prop it up my canopy will be uneven regardless. I guess thats why i decided to join this forum so i could get your guys ideas and feedback. Very much appreciated!

Also I literally just watered them again with 3ml's calmag in a gallon of water.

You need to find out what the run off is cos if the PPM's are to high inside the pot it'll burn once it starts to get a bit dry 550's a bit high for plants that size as well imo.

Thanks for the reply. I worked on PH and PPM's during feedings, looking better now.
