Grey_Wolfanswered grow question 5 years ago
@Maskelyne Hi that is a nutrient burn from over fertilising the burnt leaf tips are the giveaway it should recover fine if you reduce the strength
Trueorganics84answered grow question 5 years ago
@gray_wolf I think you may be right. Sometimes it can be light burn. But the tips of your plants aren’t all effected.
What’s your ppms? Or ph
Also growers recharge is good for this. Helps balance her out and gives the plant a chance to absorb more Potassium and phosphorus. Before fuckin with your nutes. Check Ph
If PH is good. Either cut in half
Or just use less.
PS:
This is why I go true organic.
PH and over nutes are never a prob.
The plant takes what it wants. Instead of you telling it.
Good luck man

Why does my pH keep changing in Germany? I set my water at 5.9 then it shifts 3-4 times over few hours, causing lockout if I water my plants with it, In Ireland, I never had this issue. Using Advanced Nutrients A+B, Big Bud, Overdrive. Could German water be the problem? Any fixesLeaves. Tips - Burnt

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?Leaves. Tips - Burnt

Is this nutrient burn?As a beginner it is hard to classify that: Are the brown tips a sign for nutrient burn? Or rather a deficiency of something?
Soil pH (out of whack) 7.4ish. Fighting that for weeks now...
Soil EC ~ 2000 µS/cm.
Crazy Hills fertilizer as scheduled.
Thank you!Week 7

Yellow tips at bud-leafsWhat is the worst case of what could happen to the buds and the harvest due to the yellow tip burn?
Since 5 days the near leaf buds have yellow tips.
It could have any reason. Flys, high ph, to high nutients.
