Need Expert Opinions!!! Please LOOK!!

These are 2 leaves from 2 different rooms. This is a problem that has been spreading slowly throughout the room. I have no idea what it is, but we have guesses at PH flucuation and maybe a deficiency of some kind.

Pro Mix with Dolomite Lime
Advanced Nutes-3 part Grow, Micro, Bloom mother plant formula at half strength
Thrive Alive B1
Grozyme (once a week at the most)
Floralicious Plus

* alternate water and food
PH 6.2-6.5

Foliar feed with Ralphs LUSH (once a week)

Temps and ventalation are good

Note : They started great and for 8 weeks they were progressing then I began to notice a complete yellowing of some leaves on the oldest mothers. These are in 5 gallon pots. It then spread to all including the 1 gallon pots. I have since began to transplant. The yellowing starting in the lower leaves but now appears anywhere on the plant.


I REALLY need help with this problem. 3 times I have posted with little or no response. Please anyone who feels they can see what the problem is, please let me know. Thanks

Well I can understand why your not getting replies as you have what appears to be several problems

Myself I use Dolomite but also add sphagnum moss because dolomite raises ph over time and the moss has a ph of 3.5 together they buffer very nicely, so without knowing how much dolomite you added? it is possible you have a ph problem causing a lockout?

I would not feed thrive alive ever, but that's me, it's a vitamin not a nute and if anything like superthrive can kill plants if used wrong

the damage in 3rd pic looks like it's from your folier feeding?

Know nothing about AN, don't do cana specific nutes but your leaf pics are defs for sure, could be the nutes or a lock out, since promix does not have nutes I would be more inclined to use DynaGro which has all 16 of the required nutes in every feeding

Hope that helps and hopefully someone else will chime in?

2 or 3 cups per bale of Pro Mix. The soil u mention is not in Canada. They have had plenty of success with Pro Mix in the past. As for keeping mothers happy for a long time this is new to them. That is NOT burn from Foliar feeding is does look like it, but I can assure it is not.
AS for B1 vitamins, it is widely used in cloning, the people who taught them their methods use it regularly for soaking mediums and preping moms for cuttings. Hell, I don't know. Thanks for your response.

The are 2 different rooms at diff locations. I just help out my foaf to get answers

I agree that vitamins are used for cloning but not for feeding!

and the spagnum moss I buy comes from Canada, Canada is famous for its peat moss

it does not sound like to much dolomite

take your word on the misting thing

other than that I don't know???

Wow, I've never seen anything like that. Are you sure it isn't some kind of pest problem? It isn't spidermites,(thankfully.lol) but could be something else.
