late in crop problem starting to appear

hey gang

i'm two weeks from harvest and have three plants in a row that seem to be sick. the leaves start to look wilted and narrow (curl under), then over the next day or two the leaves start to look dark and dead. the only common trait i noticed was a slight green (algae-type) look to the top of the peat puck. i moved the spaghetti hoses back slightly in case i am overwatering onto the peat puck. i am using hydroton and gh nutrients and have been seeing decent results until this point. all the sick plants seem to be on one table. i took the first one out and threw it away in case it was a disease. if it is it is spreading...any ideas? the other plants right around it look fine but you can definitely tell that one is sick. help guys im stuck...

looks like the plant is under watered. lower leafs will yellow always as you get closer to finish

cant really tell but it looks like cal/mag or potassium...you got any other pics..peace az

it is not underwatered, if anything it seemed overwatered to me...leaves really dying now, plant maturning much faster than the ones around it,

I did some research and peat cups/pellets are all natural and need extra care when it comes to watering correctly. Peat will grow trace mold that should not effect the plants under normal conditions, but under too wet of conditions the trace mold will grow to a problem fast! Judging from what u said about possibly overwatering I think u have found your problem. I would transfer those plant to their own tub (u can make a DWC for cheap and finish them in there) or chop them early and mix them in when your buddy needs a bag....lol... Whatever u do I would keep them seperate from the otherones until u know its not mold or fungus. They should be able to share the light but I wouldn't share the res. Its not worth losing the crop to mold on the last two weeks. Keep your humidity as low as pos.. 50% or under, good luck... By the way all the other plants look beautiful good work...

bump its right here dam

imma keep bumping both till he sees it
