spots?

[mike myers mask]

hey all, i have a real problemo with my girls.

week 4 flowering

they have spots on them... rich green leaves, but spots are developing..

400 watt HPS, 80 degrees F room temp, average humidity. soil. 3 gallon pots. about 5 feet tall

GNATS are a constant problem, i am killing them now.

I give them micro supplements in small doses, once every few waterings, as well as organic fish nitrogen, bio bizz mollasses and ONE cap of hydro flowering nutes per 3 gal of water

sometimes they are lacking in water when i slack on watering them, that and the gnats are the only problems i can think of.

would either of these cause sudden spotting, leading to leaves burning and curling up and dying?

Def micro mute problem...pics would help but sounds like cal mag

You sure you don't have mites?​

You sure you don't have mites?​

i checked under the leaves, nothing is moving.

if there are mites, they are very inconspicuous

plus, this damage is only on the big leaves for the most part

so u guys think its cal/mag deficient?

i checked the micro nute bottle, there is some mag but zero calcium. biobizz grow big molasses i thought had some. and tap water has some, which i use.

I'm almost 90% sure you have mites.......a couple more pics under natural lighting would help........I would toss that plant and pray they haven't spread; doubt it though. Once you see webbing it's game over, I would treat immediately.

i checked all over the affected plant, zero mites. I should at least be able to see ONE with the naked eye, if mites are indeed doing this.

here are some more pics. as u can see, most of the foliage is healthy, but these spots are slowly spreading.

Calcium the final verdict? anyone else want to weigh in, calcium or other?

You got a loupe/magnifying glass to confirm no mites?

What's the ppm of your tap water?

There is a deficiency there, but mites also like to attack the weaker plants so there's that.


Only one calmag post and all the others say mites... So that can only mean you need to add calmag right?

again, i checked the plant, no mites. spider mites aren't really a problem where i live

and my micronutes dont contain calcium, so, ya, conclusion seems self evident.

i will dig my magnifying glass out and check closer but i know you can see mites with the naked eye

EDIT:

I ALso just read that root APHID damage mimics cal/mg deficiency... i have gnats, and they are on the roots, are they doing this?????

i got new micronutes that have cal mag in them, and im killing those g-damn g-nats
