I have did have spider mites have sprayed once with neem oil last Saturday sprayed with green cleaner tue and Thur and will spray with neem oil again Saturday
 
That's is what is going on with the leaf color. Feed your plant with nutes but do not diagnosed it as a nutrient problem until you have eradicated the spider mites. They are Penske little SOB's so make sure you are checking everywhere.
good luck.
 
Only plant I have doing this. But it flourishing with new growth. Not too concerned .

Nitrogen deficiency? It's the only one of it's kind in the group experiencing this yellowness. Is it a natural plant cycle. Or does it need a bit more nutrients than the others .
 
Davedude
that is not a natural part of the plant cycle, ultimately a good grow will have next to no leaf yellowing or die off unless it on the plant lower part getting shadowed or being flushed, So you are having a problem.
looks more like magnesium or phosphorus then nitrogen but I'd need more details, Soil? Coco? PH? Calmag? Nutrient schedule?
 
I'm a beginner. Be gentle. I used a reg promix soil, myco in it. No Coco. pH is 6.7. no calmag or nutrients. Just dustilled water. Has been transplanted. Used root enhancer. If I'm adding nutrients what do you recommend.
​​​​​​
 
I try to always be gentle, so I dont grow in promix but I do know that you need to feed them and your other plants will start to look likel this if you don't soon.
Your going to need to get them some calmag asap and a base nutrition.I would also question the PH for PROMIX, I think that's a little high.
I'm not selling you on a brand just a example, I use Fox Farm and Big Bloom is the base that goes in every feeding while grow big and tiger bloom come and go during the grow.
Here is a link for ideas on nutrient lines
https://www.growweedeasy.com/nutrients
I believe you need to treat your promix as a soilless medium pH range 5.5 to 6.5, I'd start there.
 
An unreliable source told me to add vinegar to my watering to lower ph level? I'm sceptical. Root farm sells pH down , I'm considering that over vinegar.
 
Lemon and vinegar work in a pinch for down and baking soda can up, never use the two together only up or down, but store bought PH down is the industry-standard and a little more consistent.
PH is #1 important, if its off you can give your plants nutrition till your blue in the pocket book and they won't uptake it.
 
Kicking myself for using distilled water, been told hard tap water increases calcium and magnisum and lowers pH. True?
 
Yep. Most tap water comes with trace elements like copper, magnesium, iron, sulfur, calcium..........and has a base PPM of 150 to 250 depending on the area. Well water would be best as to not included such things as chlorine, bromine, fluoride..... used to treat city water. Any time you use reverse osmosis, filtration, or distilling you are removing Trace elements from the water and will have to replace them with what you want. Reverse osmosis is popular so a grower can control every aspect of the PPM. PH will very from area to area depending on what is more available, acid or alkaline.

Question I use city water but leave in open container for 24 hr to get chlorine out is this true way to get chlorine out is this a good idea?
 
Yes, if your city uses chlorine leaving the container open will let it evaporate. Some places do not use chlorine, you can check your city's water data they are required to make it public.
Sorry we jacked your thread.
 
Like most other growers I leave water to air out for at least a day. I also keep a large 6 gallon container to fill gallon jugs for feeding.
This is waht General Hydroponics says on it site about water and chlorine.

'My water is chlorinated, Is this a problem?
Chlorine is highly volatile; it evaporates as soon as it hits the air. By the time the nutrient solution reaches the roots, the chlorine is gone. '

No matter what it says about chlorine dissipating quickly, I still wait before using it.
