Think different NFT problem

HI all.
I have a little problem with my plants that i dont know how to solve.

FIrst of all lets say that the babies are going really well but at a certain point i have an issue.
After the 6 week when the bud start to develop in lenght its like that they enter in the final stage of flowering. They stop their develepment in lenght and they begin to ripen with the result that the overall yeld is really poor.

I already encountered this kind of problem but i dont know how to solve it. The ec should be fine:1700. The ph is fine the temperature and the humidity are right. I change my reservoir every 3 weeks.

I really dont know what to do to avoid this problem. If someone wants other kind of information to help me, let me know.

Hey @megalexxx ,If you can provide some more specific info it will help diagnose the issue better and some pics will help,,,,nutes,levels,lights,distance,media..basically give numbers and such,,somebody should be along shortly

 

[megalexxx]

Ok well
Nutes: acqua flores+cannazym
Lights:2x250w+1 400w 30 to 40 cm from the top
MEdia:rock
Ph: 5,6
Ec 1700
Humidity 60%
Room temperature: 22c Temperature on the canopy 26c
Water temperature 20c

Take some pics in regular light and I'm sure the experts here will be able to help. I made the same mistake. Lol.

Here the pictures. Maybe an issues when i change the reservoir? I really dont know
However if you guys need some other information let me know

Hey @megalexxx I'm not the expert,so these are just my thoughts,the 4th pic shows nitrogen toxicity type clawing( but not saying that's what it is)..in flower the humidity should be as low as you can get it,lower the better,but I know that's sometimes hard to work with,maybe better air circulation or a small dehumidifier,,hang tight the pros will be along

 

[megalexxx]

I really cant understand where is the problem. Is the second time that i have this kind of issues. The plants looks really well and everything is pretty well balanced, but they begin to ripen too early. I've searched all over the place but i cant find an answer to this problem

Not an expert either, but looks as N toxicity to me too, makes sense with the shiny dark leaves and poor bud development.

 

[megalexxx]

Thanks for the answer
It can a be a N toxicity??
I usually go acqua vega for the first 3 weeks. Then i change the reservoir and go with acqua vega for another 2 weeks. Then i start adding to the reservoir some acqua flores and i completely go with acqua flores at 6 weeks.
So guys you think that the plants are taking too much nitrogen and at a certain point they completely stop their grow? Because i see that the buds are growing really well and around day 40 they completely stuck.
Maybe i should go only with acqua flores after 4 weeks?
