downard curl

[sandman4090]

My plants are about 1 month old, grown in FF oceanforest, temp stays around 80, I water when needed, but the tips of my leaves are curling sharply downward on one of my plants. I am not sure if it is normal but most all the leaves are like this, some worse than others.

It could be a fert overdose problem, or maybe heat related, but 80's not bad. Try a good heavy watering to see if it calms down. Some strains are touchy that way. What strain BTW? Soil? Hydro?

bag seed, I just transplanted into fresh Fox Farms and I have been adding 1/4 strength organic nutes so I'll stop giving them nutes for a couple weeks

I actually haven't tested since the transplant I hear the soil and the nutes I have been usin are ph neutral

Are the leaf tips curling down, do they have yellow margins which are turning into dark dead spots?


Potassium (K)
Potassium is involved in maintaining the water status of the plant and the
tugor pressure of it's cells and the opening and closing of the stomata. Potassium is required in the accumulation and translocation of carbohydrates. Lack of potassium will reduce yield and quality.


Potassium deficiency (K).
Older leaves are initially chlorotic but soon develop dark necrotic lesions
(dead tissue). First apparent on the tips and margins of the leaves. Stem and branches may become weak and easily broken, the plant may also stretch. The plant will become susceptible to disease and toxicity. In addition to appearing to look like iron deficiency, the tips of the leaves curl and the edges burn and die.
Potassium - Too much sodium (Na) displaces K, causing a K deficiency. Sources of high salinity are: baking soda (sodium bicarbonate "pH-up"), too much manure, and the use of water-softening filters (which should not be used). If the problem is Na, flush the soil. K can get locked up from too much Ca or ammonium nitrogen, and possibly cold weather.

Potassium (K) Toxicity

Usually not absorbed excessively by plants. Excess potassium can aggravate the uptake of magnesium, manganese, zinc and iron and effect the availability of calcium.
