Hello guys.
I have some problems and as much as I read everywhere it gets really confusing for me to determine what is the exact problem.
My problem is that some ( 4 out of 8 ) plants are turning their leaves light green to yellow. some leaves are completely yellow and have brown tips ( looks like rust even ).
I should be feeding them correctly. I use b'cuzz A + B. bloom stimulator according to their instructions which are :
3 ml of each A & B per liter and 1 ml of stimulator per liter.
b'cuzz A is n-p-k: 4-0-4
b'cuzz B is npk: 0-3-4
Usually i know yellowing can be caused from nitrogen deficiency but it's already inside the solution. Also they are in flowering stage so nitrogen shouldn't be needed so much from what I know.
My suspicions are:
Gnats: Sow just one gnat maybe long time ago but freaked out and put a gnat defender on top of soil. Right now havent seen any ,but maybe I have aphids.
Nutrition products that I use are not that good maybe ?
Don't think it is any type of cold/light/heat stress.
Don't think is overwatering ( leaves are not dropping - even the yellow ones ) although recently i started increasing the nutritions and was rewatering almost each day to try to fix the nutrition balance ( will stop for a while )
Was suspicious about a sulfur deficiency or a potassium or a phosphorus deficiency too but am not an expert and all the pictures I've seen don't look like my problems.
I use mineral water Aqua pura:
Calcium: 14
Magnesium : 3.5
Potassium: 2.5
Sodium: 12
Bicarbonate: 20
Chloride: 17
Sulphate: 14
Nitrate: 35
Dry residue at 180C: 135
Fluoride: < 0.1
Ph at source : 6.1
I saw a post stating to go there first regarding problems but all the pictures there are missing: maybe it's because I'm behing a vpn.
also really sorry that on some picture the hps is on ( also saw that ),but on some of them you can just see the burn. Took the pix yesterday and saw the post about that today, but I'm so desperate.
Thanks,
