So based on this, the first sign of flowering was 7 weeks ago, if I have 4 weeks left, should I worry about the lightening leaves that are turning the plant light green/yellow?
Sorry for the continued questions but I just want to make sure I do not need to address any deficiency or other issue…. Please see the picture below where you see some curling and brown spotting leaves…. Most of this is on the top growth bud area not on the lower leaves…. One thing to note is in order to keep the runoff PH at about 6.5, I have been having to PH my feeding water to 6.9-7.0 through most of the grow…Any comments or recommendations would be appreciated
I’m not worried about the coloration, but the brown spots in that latest pic are concerning. What is the humidity in your grow space and do you have plenty of airflow?
That random brown spotting and overall look are signs of a Nitrogen Deficiency. Whether its from a pH lockout or wrong nutrients is unclear But I believe that is what is happening.
The spotting does not wipe off it breaks up like dry leaves when touched… pics below. A few weeks ago I was getting burning on the tips so I backed off the nitrogen to prevent further burning… I am using jacks so when feeding I started using 1/2 dose of part A and only 1/4 dose of Part B (Nitrogen) …… so should I go back to normal 1/2 dose of part B?
I might suggest flushing it well then feeding full strength with a decent run off to get the balance of nutrients back where it belongs.
I dont worry about burned tips unless it starts going up the side edges of the leaves. Burned tips is pretty normal for Jacks growers.
I offer my own pics of Jacks in Coco Coir…
When doing the full feeding with Jacks after a flush, do you recommend still using full strength part B at 6-7 weeks in on flower? I was under the impression that I should back off on part B somewhat during flower…. I.e full part A and 2/3rd part B ?
Not a good idea. The most rapid growth a plant will experience is during the “stretch” which is the first 4 weeks of flowering. It is the nitrogen in Part B that powers that growth.
You can, but it’s not going to make much difference, as wet soil does not absorb nutrients very well. Resume full feeding on the next watering after the soil has dried out.
I am not a soil grower. But doesn’t happy frog have nutes in it all ready? If so. Adding more on top of that could be an issue. I have fed 25% stronger with jacks in coco and no issues. it is super forgiving. My pc lost a lost of my pictures with this last re do I did. I just did a purple punch last grow. You still have a long ways to go like they say. The buds for this get nice sized.
Can you help clarify something, because I’m slightly confused on the timing…. I noted that I was in week 11 from seed, but had received info stating from first sign of flower would be 8-10 weeks.
What I am growing is Autoflowers, not photo period, and from information I see online, typical autoflowers are 8-10 weeks seed to harvest.
