Dealing with Nutrient Burn and Salt Build-Up
Cyborg420started grow question a year ago
I've observed salt build-up and nutrient burn in my plants recently. I've taken action by flushing and removing 60% of the affected leaves. Now, I'm considering whether to remove the remaining affected leaves and when to proceed with top dressing. Please advise.

In my view enough removing leaves, she started blooming, she needs the leaves, new leaves wouldn't grow, and is an auto try not to stress her too much. For feeding cut the dose so you won't have nuts burn 🍻

Para darse cuenta cuando volver a fertilizar mida el ec del drenaje de su maceta si le de por debajo de 1.2 ya puede volver a fertilizar, de lo contrario siga regando con agua sola. Su planta se ve saludable no está tan mal

Small brown points on older top leaves1 week ago she started to get small brown points on older top leaves,and I moved her away from light to exclude light burn. Now there are a lot more of them. I flushed her 5 weeks ago, now she is getting full dosage of nutes. But these points look like nutrient deficient to me.2 years ago

Forbidden runtz excess or deficiency problems autoflowerBAD WEEK! need some help here guys..
Brown / rust spots started to appear on the tips and slowly started yellowing leaves.
Im following the master advanced nutrients chart and watering 2 times a week.
Last week feed was
20 litres R/O water
80ml bloom A
80ml bloom B
40ml of every additive on the chart
20ml cal meg
30ml phup
PH adjusted 6.50
After i started noticing the brown spots / leaves curlin up and stunted growth i skipped a feed and flushed with plain R/O water used 30 litres for 4 auto plants.
Yesterday i watered again but cut the nutes in half.
20 litres R/O water
40ml bloom A
40ml bloom B
20ml of every additive on the chart
20ml cal meg
20ml phup
PH adjusted 6.50
I still don't know what the problem is, if it is a excess of something or a deficiency..Looks like a cal meg deficiency but ive beed using cal meg since the beginning. Maybe i have excess nutes in the soil and resulted in nutrients lockout of cal meg or something else?
since i water twice weekly should i water with nutes always ? The master advanced nutrients chart still sometimes confuses me.
Please any help will be appreciatedWeek 8

Not Nutrient BurnWell I'm stumped...ppm 600, pH 5.9...it certainly looks like nutrient burn but it can't be, tips yellow then darken and curl and get crispy. 3 days between pics in question and in diary. My only guess is that I upgraded from knockoff 100W LED to Mars Hydro 150W. Any ideas?2 years ago

Burned tips and holes in leavesHello! Hoping to get some insight into why the leaves on this girl have holes and the tips are breaking off. Thinking maybe nutrient burn? I’m using slow release nutes from Gaia Green. I used premixed coco I had already amended with 3 tbs/ g of 4-8-4 and 1 tbs/g 2-8-4 top dressed2 years ago
