So this is my first run and i had run into some ph problems in late veg but got that squared away and was looking good again. Now that im mid flower some of my plants are showing signs of nitrogen and i think calcium deficiency. Also the ones that seem deficient also have a lower trichome density.

It could be light not reaching the bottom leaves. The plant will stop feeding or take moble nutrients from one area and move it to where it is needed causing the yellowing on the bottom. The plants look good and healthy. Are they auto flower?
No photo period. Another thing ive been reading up on is root bound. They are in 5 gallon pots and they are pretty big so i was wondering if anyonè had experience with this issue and found out it was because the roots were root bound. One of the signs is nitrient deficiency.

Do you use a y kind or root treatment like calmag
Never mind didnt notice they were bags. I only do hydro but some thing are similar.
I have been using an increased dose of calmag. They probably only have 3 weeks or so left before i harvest and im wondering if they are rootbound, is there any thing to worry about this late and or is there anything i can do
Lets see if one of the people who grows in the same medium to answer.
I know all the bigger leaves turn yellow as the plant puts its energy into growing buds and that is normal.
Check this video out on youtube. I thought that it was cool.
It shows the entire life cycle of cannabis
Yup that video is awesome. What an awesome plant
I was also more wondering about the potential calcium deficiency with the rust spots. And again i really need to know if them possibly being root bound is gonna be an issue this close
I honestly don’t have never grown in cloth pots like I mentioned above. I know the ph is a little higher in other mediums vs hydro. What is the ppm of the run off you are getting. I know sometimes adding more nutrients because of a deficiency that is caused by ph will not solve the problem.
Beautiful pics…
So my ppm is running high but it seems to be because of the organic top dress ive been doing. The forst time i experienced this i flushed them an extra time and thatsvwhen they starting showing signs. So ive been just lind of ignoring the readings as the plants dont look like theyre going toxic. Im just worried that all this confusing stuff is happening due to them being rootbound and that its gonna affect the end game
Also, and i dont know if this makes sense to anyone, but the ones that are showing the calcium deficiency are the frostiest ones
The buds look good. I dont add calmag past early flower. I tried that once because like what your pics shows calcium deficiency and nitrogen. The end result was big airy buds. When I researched it, it was caused by calimag and too much nitrogen. The last week or two it is completely normal for yellowing.
