Guide to Nutrient Deficiency or Toxicity

Hey guys. I'm using the flora series and am on week 3 of 12/12. I just watered today and realized after that I haven't been giving my plants enough. Its safe to say I've been giving 1/4 of what I should
Plants are looking great but just wondering thoughts from others..should I jump right to the correct amount next time?. I water once a week with feed.. should I not be so worried?
Any help would be appreciated

doesn't nitrogen deficiencies start to yellow the leaves on the bottom first then work their way up? iron deficiency starts with yellowing of new growth then works its way down. Normally caused by off PH

Thanks for the info.
It help alot , what would be the best way of getting iron to my plant?
Would I find bottled nutes high in iron?
What will I use?
And can I find it in a horticulture or grow shop?
Also what would be the healthiest way of getting nitrogen to my girls?

(All my plants are being grow outdoors)

compost for nitrogen. any grass, broken and dead branches. Anything that used to be green or brown, can be used. get a box like a Rubbermaid container and drill holes in it. the sides and the bottom. then put all of your grass clippings, dead or dying foliage. It takes a while for compost to be ready. around 3 months oh and you got to keep it wet and take a rake and stir it up at least every three days or so. But in your case, you don't have that time to wait, so go to your nearest nusery or Walmart. they have it. bags of compost. or compost tea, it works faster. Its just water ran through compost and collected. spray on foliage and in soil. your plants will thank you for it.
Iron is one of those micro nutes that is usually found in soil. First thing to do is check the PH of your soil. If that is over 8 or under 6 then that could block your plant from obtaining iron out of the soil. if your soil is lacking iron you can simply stick a nail in the soil. as the moisture reacts with the iron in the nail, it will form iron oxide which your plant can use. one nail. don't go dumping a box of them down . you will turn your soil toxic. there are plant foods that have iron in them. tomato plant food has iron and evryother nute that your girls need. But first I would recommend checking the PH first

too much iron is a bad thing make sure that is your problem before you start adding things. a fertilizer like earth juice grow and bloom is simple and complete you don't need to add anything to it the powder is fairly cheap and you can top dress it and just water. keep it simple.

Looks like plenty of nitrogen to me, it would first steal nitrogen from the lowest leaves until they were totally yellow to feed the upper leaves. The best way to stop an iron def if that what it is is to correct the ph, around the lower end of soil ph range, 6-6.2

Edit, unless you are watering with RO water which is void of iron

Double edit. Cal Mag also contains Iron as well as calcium and magnesium, the 3 work hand in hand with each other. I probably would be checking its not a PH issue first but if you do happen to be using RO water then you should be adding something like CalMag anyway (assuming your not in organic soil)

There where a few days of light rain and was very cloudy and a bit windy.
It was the first time they have experienced conditions like that.

I check the ph of the soil and it seems to be ok at a steady 7.0.

I had a few bags of compost and filled one with water and left it sit over night. Then poked holes at the bottom and drained the water ina bucket ph'd it to 5.5
Then spread it around the soil. Hopfully it will lower the pH a bit and give the soil some extra organic nutes .

This is the same Leaf I took this pic
Dismorning before I spread the ph'd
Water. It's seemed to be curling up now mabye from the wind?

IMG_20160621_192543.jpgThis is the leaf on the other side It looks like its getting better.
But the bottom leaves are starting to do the same.
I'll upload a pic in a few days to see if the ph'd water made a difference.

Water I use is just rain water ph'd to 6.0
No lower leaves are yellow at all all green.

This is a potted plant
I noticed the lower leaves have turned a dark green with purple around the edges.
Cold temps?
