Nute burn???
Chimney_Chiefstarted grow question 4 years ago
New growth on my plant is showing signs of minor nute burn, havent fed the plant in over a week now and have only been topping up my DWC system with Ph balanced water as the PPMs were telling me shes drinking more water over nutes. A lockout due to feed change maybe?

roots don't really selectively absorb nutrients. i don't believe any active transport is invovled, but could be wrong. too long ago..
anyway, evaporation will always cause ppm to rise. you have a small plant, so it's not drinking a ton daily. Keep those ppm in check.. maybe drop them a bit if a leaf chart and recent behaviour cannot deduce exactly what it is.. K-tox?
Bongkhananswered grow question 4 years ago
would recommend changing the reservoir solution one every 4 to 5 days and see if it helps. in hydroponics ; it so happens that the ppm or ec count remains the same but the plant has actually used up some nutrients and they even exchange back some in water ; creating deficiency in one and excess in other ; also many hydroponic growers do not suggest topping more than twice a week ; as they altogether change the water or keep a circulating system of solution. so changing whole reservoir water should definitely help you in this case.

help! my plant is turning pale. the green color is losing.the green color is losing. some leaves burn from the tip to the stem of the leaf. Excess fertilizers (because I fertilized the soil) or deficiencies due to few nutrients? I also thought that it can burn with nearby lights, but the ones that burn are far away

Thrips damage or deficiency/ toxicitySeems like I’m having a deficiency or excess of some sorts in my plants. Also I’ve had some thrips but I don’t know if this is going to be related it or not. Older fan leaves are darker green band some have some purple in the stems. Some browning on tips

Sick leaves, good budsSome leaves look sick. (Last photos at 8 weeks) Is this an overdose? Do I need to fix this? From fertilizers, I apply only ripen. I plan to give it 2-3 times and then flush and harvest.
I know that ripen helps to end life and makes the leaves turn yellow, but not so!4 years ago

Nutrient burn/Lockout? PH LowSo 1 of my plants is having a hard time in my low PH Soil I'm seeing the start of brown tips on newer leaf growth. I was wondering if I should water frequently and keep the soil more wet with higher PH water or let it dry out and slow the nute uptake? and risk high PH at roots?Week 4

Deficiency/Light Stress IssuesWhat else can I do? Brown curled tips and spots on older fan leaves climbing up towards main cola. Flushed with pH’d RO yesterday, but was only able to get pH to 6.7, also added small dose CalMag at end of flush. Light wattage has also been reduced by half for the last week.

What is going on with these leaves?Tips of top leaves slightly brown, no curling. We had some hot days where humidity was kept low, but heat from dehumidifier plus outside temps got up to 91f. Some leaves at top have strange marks a bit concerned. Living soil, Marphyll, bat guano, molasses only.
