HELP! Growing problem or problems

[Duester]

Hello everyone 👋 I am new to this forum.
I have been trying to grow indoor cannabis for almost 4 years and failure is what i harvest , lol .
I don’t know how to start but here it goes. Currently my grow media is Coco Loco. I clone well with it also.
plant food for veg and bloom is Dutch Science. I use tap water & the ph is 8.1 - 8.0. I use the crystals which look like salt or sugar to lower the ph .
Bought a Apera ph pen. Bought a mars hydro fc-6500 light.
The plants look and grow well . The problem seems to be the bloom phase. The flowers start to smell good around 30-35 days into bloom then suddenly no more smell . Lower leaves start turning yellow one by one . By the time the plants should be ready, they haven’t grown much more since the 35 day mark .
Mots advice I have gotten was from grow shops around here. Every one of them has closed making getting the supplies I need more difficult.
Good solid advice is what I need . Looking forward to getting just that !
I apologize if i started this issue incorrectly .

We're simple folk who like our weed porn. A word is not worth a thousand pictures. We can tell more from what the plant looks like than from what you tell us.

Yellowing lower leaves during flower is pretty normal.
What about your grows makes you consider them failures other than the buds not growing enough after the first month?

Got any pictures?

It may be too hot or cold.

It may be crap genetics.

But it sounds like you are somehow stressing them and that is stopping flower development.

No idea unless you give us all the info related to environment, lighting intensity, amount of nutes, pH inputs etc..

And pics

Maybe over watering. Sounds like day 30-35 with yellowing leaves ? And no smell. I'm thinking u have less nitrogen than u need at that point in flower. Pics and watering schedule would help us diagnose

We would love to opine and provide the wisdom of the ages to acolytes such as yourself. However to reap the opinions and views of the great masters, you need to prove yourself by undertaking a quest and delivering to us the following items:

Pictures and details illuminating your issue
A complete list to your nutrients, amendments and how much and often you use them.
Temperatures and humidity
Height of light above your canopy as well as intensity

You seem to have a decent light and PH meter.
Get rid of the "crystals" and just use PH up and down. Its no different and easier to quantify.
