Nutrient Level

This is my first grow in bubbleponics. My ph is kept around 5.9-6.2 with ff nutes at about 1005ppm. the plants are in the 6th day of veg. the problem is the plants don't seem to be eating, the ppm is climbing. any ideas oh the water is kept about 74 deg f

The ppm climbing is an indication that the plant is being overfertilized by taking more water than nutes try to back off the nutes maybe at 3/4 strength next change over and monitor the ppm that should resolve this issue.
I would drain about 1/3 of water in bucket res or whatever your bubbling in and replace with fresh water.
Good luck

Thank you. I use a 27 gallon bin with 10 gallons of water. I will replace 5 gallons with fresh ph'd water to get the ppm down. thanks again

I did a water exchange and adjusted from 5.9 ph and 1095 ppm to 5.5 675 ppm. I'll try that for a few days and see how it goes I also have 2 plants that are ing the same tank both White rhino and their leaves are growing with pointed edges. I'll try to post pics

Definitely give them a few days luckily in hydro you will know if it works within 24 to 48 hours most times sooner, the 5.9 ph is fine when resolving issues with nutes, I have found that keeping the ph 5.8 to 6.3 a little alkaline seems to work best, this allows more buffering through the plants process of assimilating the nutes, then once they start going good again you can adjust down if needed

75 degrees is too hot for Hydro, get the temp down to 68 to 70 or there will be trouble later.

The root zone temperature needs to remain consistent for ideal growth rates. Root temperature is more important than leaf temperature in achieving plant growth. Water should be room temperature not cold if your room temps are in the 80’s your water temp at 74 degrees is ideal, cooling the water is only if water temp reaches temperatures higher than room temp and it doesn’t look as though that is happening, or if you’re dealing with hardy plants meaning colder temperature adapted species. If it aint broke don’t fix it!!!
