Help w hydro

So my plants have been on and off okay, this is my first attempt. I have a 600w hps dwc hydro system. 6" vent fan, 1 plant has 6 gallon resi. The plant started flowering fine and now this. Any help would help. I adjust ph daily, use ro water, and house and garden aqua flakes nutes.

Not sure man, never used the home and garden aqua flakes. I would start by changing the res and switching nutrients. The 3 part General Hydroponics is tried and true, I would go with that. And your keeping the ph at 5.8?

whats your temperature looking like? it looks overheated

room temp is around 78 with lights on res temp is 75, and ph is always checked daily and brought to 5.8

first thing you say that tells us something is you are adjusting to 5.8 everyday. why? what is ph swinging to? the first thing i noticed was burning/clawing of leaves from nutes too high. then i see your res temp is 75, not good. in dwc this will get you every time. if you dont have some root issues like rot or just puny roots you will. i would check roots and add ice bottles to lower res temps. also adding a beneficial bacteria like pondzyme or great white would help protect and build roots.

Yes I can almost bet its you warm rez temps, was having the same issue with this hot summer. Best replacement is a cooler, or putting your rez into another tub of water and doing the frozen bottle trick. You want it to be down to 68' to get those pearly white roots

it is no problem to add ice bottles to your res. k.i.s.s.

Can I add frozen water bottles directly to the res of they are clean?

yes, i did it for years

Thanks for the help everyone. I think it is a root bound problem. My roots are huge and working with the plant is becoming difficult. Needless to say it doesn't fit into a five gallon bucket anymore for a temporary stand when I am doing res changes. But that's not a bad thing either
