Just keep doing what you're doing. Maybe lower PPMS a bit, but that damage is done and can't be reversed so just hold out til harvest.

Yes, sorry for posting in the wrong thread and for my lack of information. I meant potassium deficiency when I posted this. I thought a problem could be identified without knowing the nutrients used.

I am in week 5 of flower, I use the flora series by general hydroponics under their recommendations. In week 5 of flower I am using 2.5ml of grow (green), 7.5 ml of micro (dark purple/red) and 12.5ml of bloom (pink). All units are in ml per gallon. I'm also adding 5ml of floroliscious per gallon (not floroliscious plus) and 2.5ml of liquid kool bloom per gallon. The light is about 6 inches from the canopy as the manufacturer reccomends for this light. My temperatures are 84F during the light and 70F during the dark. Each plant is in a 5 gallon bucket with plenty of oxygen.

You mixing micro VERY WELL first, THEN GROW, Then Bloom?

You're problem (IMHO) is just using too strong of nutrients. Use 3/4 strength of whatever you're now using. This is my RECIRCULATING schedule for flora trio. It's all I use.View attachment 3737895
Thats a lot less than mine. I believe in the final 2 weeks of flower its having me use 15ml or 3 tsp of bloom per gallon! No wonder why every time I watch a youtube video their water is always clear and mine is dark.

Glad I could help! What type of system you growing in again? Or is it coco or soil?

its in 5 gallon buckets (DWC). But I wont be doing DWC again though. I started a coco grow 3 weeks ago in my other unit. Growing 20 plants, 5x5 tent in 2 gallon fabric pots using the head formula. I'm much happier with a shorter, flatter canopy that fills the foot print of the tent much quicker.

Awesome I too run RDWC and am addicted to it. I love it. Definitely run the schedule I gave you then and you should be just fine.

I like the yields but it's hard to change your buckets with a scrog. If my yiekds with coco are good then I might abandon DWC

Why would you change buckets? You need to get a RECIRCULATING dwc going. It's much much easier. Build it. It's so easy.

Just use donut grommets from Hydrofarm and barbed plastic fittings. Drill your holes, bigger on bottom for gravity returns, smaller at top for supply(waterfall)
