Afternoon fellow Percy growers, hope you're all well and your plants the same.
So I just wanted to post some photos of my auto taken this morning as im worried I may have a nitrogen deficiency. Below is a photo of all 3 plants taken just now.
The one on the left is the auto and as you can see, the leaves are noticeably paler then the other 2. Below is a couple of close up photos of the potentially sick plant and also one of the healthy ones to show as a comparison. Bit of background this auto is now on day 72 from sprout and as its in a tent with 2 photos, had its light reduced from 18 to 12 just over 4 weeks ago. Feedwise its been getting exactly the same as the other 2 plants both of which are looking healthy with no issues.
SEEDSMAN
ZKITTLES
As you can see the 2 photos of the seedsman shows much paler leaves and yellowing starting to spread over the leaves.
So I guess what im asking is am I looking at a nitrogen deficiency here and if not what do you think it could be?
If it is nitrogen, as ive just entered week 5 of flower, ive stopped using any Gro Nutes which naturally contain the bulk of the N and instead fed just Bloom(4ml) and Micro(2ml) per gallon, this morning. The NPK ratio on the micro is 5-0-1 so there was some N in there. If it is a nitrogen deficiency will this be enough or should I of upped Micro just for this plant?
Hope ive made sense with all the above, anything else ive not made clear, just let me know and any advice would be greatly appreciated.
Thanks in advance.
@redeyejedi defintitley looks like the start of a nitrogen issue, however given that your in week 5 of flower, near the end of the cannabis plants life cycle the plant naturally starts to yellow a bit in the leaves, if your plant has a 8-9 week flower cycle your closing in on the end of the life cycle of her. Since you've fed it this morning, keep an eye out and continue the bloom food for now but I think you'll be ok man. Some minor yellowing is normal near the end tho especially on a late flowering plant.
@colacody Thanks for the reply mate. Yeah I had a look through the diagnosis section 1st so pleased ive managed to diagnose it correctly.
I guess that was my main worry, if id of been in veg or early flower, id of just upped Gro amount but with it getting towards the end of the grow, I didnt want to deviate from my plan of cutting Gro nutes out at this stage. I suppose I was just worried with 4 weeks to go, the deficiency might be showing a little too early but I guess with it being an auto, it could of always gone into flower before I flipped my photos. I'll take your advice though and just monitor it for now and continue with my current nute amounts. Its actually a CBD only plant that im growing for my brother so if I look at it selfishly, its the one im least concerned about but of course I still want to do the best job I can with it.
