Solution to fixing a Nitrogen deficiency

Avoid excessive ammonium nitrogen, which can interfere with other nutrients. Too much N delays flowering. Plants should be allowed to become N-deficient late in flowering for best flavor.
A goof solid N-P-K ratio will fix any nitrogen deficiency. Any chemical or organic fertilizers that have Nitrogen in them will fix a nitrogen deficiency., Peters all purpose plant food 20-20-20 is good, Miracle grow All purpose plant food, Miracle grow Tomato plant food, (Only mixing at ½ strength when using chemical nutrients, or it will cause nutrient burn!) as well and blood meal! If you need to give your plants a quick solution to nitrogen and you want to use blood meal, I suggest making it into a tea for faster use, where blood meal is slow acting, but when made into a tea it works quicker! Other sources of nitrogen are dried blood, Cotton seed meal which is slow acting, Insect eating bat guano which is fast acting. Bone meal which is a gradual absorption when not made into a tea.( also excellent source of phosphorus). Fish Meal Or Fish Emulsion is a good source of nitrogen and is medium acting. Worm castings, which is gradual absorption. Seabird guano, All purpose Millennia Seabird guano, Orginal Seabird guano All Purpose, Crabshell ,which is slow absorption. Fox Farm Grow Big, which is fast acting. ( can bring down your ph as well)


Now I have a question for you I recently cloned my plant and the one clone has a multitude of tiny yellow spots on the bottom leaves but the new leaves coming in are perfectly healthy what could this be?

Can you give a few more details and post a picture with the light of? This doesn't look like an N deficiency to me. I'm going to guess your soil ph is LOW LOW LOW...

So gimme some details....

Are you using a soil ph meter?

RO Water or Tap?

Adding any other nutrients like Cal Mag+?

For sure man.. As a heads up, I think I had salt build up, so I flushed it yesterday. Will add 1/2 dose big bloom, 1/4 dose tiger bloom on wednesday, with molasses of course.. is it cool to mix those all together in a 1 gal then water?

FFOF, Distilled water, Ph meter (http://www.wormman.com/prod_images_large/pHtestermin1.jpg), read 5.75ish before flush, 6.5 after flush. I can't post a photo with the light off cause its at my girls place. I havent added any other nutes. Only the big 3
This was taken yesterday during flush

Lose the distilled water and use tap water. Otherwise you're missing out on calcium and other minerals that naturally occur in regular old water.

Flush every four weeks. Remember to adjust ph AFTER adding nutes.

Your plant is still healthy enough to bud, but crystal production might be on the light side due to lockout.

well i just flushed and will add some nutes in tomorrow... I always used distilled because it was a good pH, where as the tap was too high and almost killed my plant in the first 2 weeks. U can use bleach and lemon juice to adjust pH right? Would I just adjust it accordingly and thats it?

A good flushing (one gallon of water per gallons in your container) will leave your plants *drenched*. You may need to set your container over a five gallon bucket while you flush to avoid overflow. Adding nutes tomorrow will add insult to injury. Water with nutes when the flushed soil dries out.

You can use bottled water if you want, just not distilled. Use spring water. Do not put bleach in your water. WTF. You can use lemon juice or vinegar, but what you need to do is get some ph down from your local hydro store.

Get your watering can ready, use spring water you've bought or tap, add half dose nutes, then test ph. If its high add half a teaspoon of ph down. Let it settle and check ph again. Add more ph down as necessary.

Your plant is definitely not starving. It has salt build up which has locked out some nutrients and given you the yellow leaves.

White distilled vinegar from the kitchen, 1 capful from the vinegar bottle per liter of water brings mine down almost a full point.

No not if you want to do it correctly. Ph adjusters are about $15 for both. This is the problem here your feeds and waterings didnt go in at 6.5 this created the yellowing, to correct the yellowing you then burnt it, your gf is right to be concerned .
Get a digital ph meter, adjusters ,have everything go in at 6.5 and this wont happen again.

well heres the news and changes guys. I went to my local homies hydro store and basically he told me this late into flower, the plant barley is taking in any calcium mostly magnesium. So he suggested that I just get a Mag nutrient. At 25 bucks I said no lol. I brought up distilled vs tap, and next time with distilled, I will for sure get cal-mag. he told me to feed like normal, but also have me some "humbolts finest" thc and resin booster. This morning we fed with 1/2 tsp of each big bloom and tiger bloom, 1 tsp molasses, and 1 tsp of this thc booster. Its 0-10-15. She looks... um, not worse. Also found out that it was sitting for weeks in drainage water which im sure fucked some shit up. Had my lady promise me to drain it each night after watering lol. Thanks guys.
