I think she’s hungry…

Do you have a pH pen? Or pH strips? Anything to check the pH?


Here is a pic. They are very similar. So tisltislmakes me believe its … Nitrogen Deficiency


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)
Here are a list of things that help fix a Nitrogen Deficiency:


No. Home depot seems to be oit everytime i go. But all i do is put hot water in a gallon and leave the cap off for 24 hours and put two cap full of dyna gro

Where is the picture ?

You need to buy a good pH meter then. And this is what I recommend :evergreen_tree::evergreen_tree::v:

Im going to try this out . Updates in a few days

Sound good @Bigbudds i look forward to results

I think the plant is good and thriving, yes get a ph reader or at least check into it when you can.
Imho- if there is a deficiency it would show on the top and the portions of the plant that are growing the most. The yellow leaves look like they are at least half way covered up by the leaves above. so they are handicapped in their function by the shade. Maybe you are light on the feeding but probably not by much.

Seasol or the fish one (Charle Carp here) the same would be a good buy too
The dirt look alittle bare

How can i spread the light out evenly on the plants. The bottom ones have alot of shade

My self I would not do anything. Plants are constantly replenishing old growth with new.
If you want move the plant and pot so the light reaches different areas of the plant, I think that’s all you can do.- You question was about yellowing of the leaves, hopefully my input helped.
Moving beyond that only with your permission. I have a couple questions
How tall currently is your plant?
Have you topped or trained?
What size pot is it in?
Discard or ignore my questions if you no longer need or want my help.

I have 3 plants and now all three og tgem have yellowing leaves on tge bottom. By my most matyre has it in the middle. Theyre in 3 gallon pots. I have not clipped any of them. As far as height they look about 7 8 inches from soil. The leaves are very concerning
