2 out of 5 plants are showing signs of nutrient burn? Soil grow
Hi, I am seeing clear signs of nutrient burn but only on 2 out of 5 plants. I feed them organic nutrients, following the chart that was provided by BioBizz. Why are they still showing burned leaves? I watered them thoroughly until the runoff was clear. But leaves keep burning.😦

Was haben meine Pflanzen?
Dear community, Newbie here :) I have two Critical Kush Autos in their 7th week that have had slight necrosis/discolored leaves since flowering. Unfortunately, I only fertilized for the first time with Hesi Bloom 5ml/L three days ago, not at all before that. More nutrients? Less light?

Yellow/ brown leaves #2 (pics didn’t post the 1st time)
Hey guys so my plants are starting to turn this yellowish color and I’m not sure what the problem could be. Sorry for the second pic, it’s kinda blurry but that’s the actual color compared to the other leaves. It’s my first grow and I’m kinda lost on a solution . Many thanks

Brown spots on bud site leaves?!
halfway through flower and now in week 6 flower one of my plants is showing some large brown spots on only the upper leaves. I’m not sure if it’s a light or ph issue as the light is close. I stopped cal mag and some nitrogen this week but spots were showing up before.

Leaves keep turning brown and yellow
It all begann with what I thought was light burn. I then considered it CalMag deficiency. Giving it CalMag did not stop it. My current guess is too low pH due to strip inaccuracies, so I gave it around 8 today instead. What do you recon, why could it keep getting worse?

Curled leaves and brown spots
Please help! My Acapulco Gold suddenly showed leaf symptoms today. Shouldnt be a lock out, I always water with drain and use lower doses than the BioBizz chart recommends. Used Molasses two days ago, could that be the cause? Its the only plant that shows this signs.

Welcher Mangel ist das?
For about 10 days now, I've noticed that my leaves are getting brown spots. Unfortunately, these are becoming more and larger. Can I still actively counteract this? Furthermore, I see small white dots on the leaf surface. Are those salts?

Response to Weezy
Hi @Weezy90, the left ones are indeed the Purple Punch. So straight water now for the last week/2 weeks? The one on the right is the NL and is 2 weeks behind the PP's so I'll lower the nutes on that one. Thanks
