1920 PPM Hydroponics DWC 4th Week Flowering

versace_growstarted grow question 5 years ago

Is 1920 PPM too much during 4th week of flowering? My bubbleponics setup is: 2x600w HPS, 3 Quick Critical+ from Dinafem Indica plants in a 45 litres reservoir. Temperature is 23°C and RH is 70%. No Nutrients burn I think (just heat burn to higher buds)

Hi mate! 1920PPM is quite high and I can see some burn on leaf tips so you might get nute burn soon. I had 1700PPM for a few days without any problems but now i changed it back to 1150PPM cos i felt its way too high. If your plants look happy then you should be fine but generally speaking its way too high.

that is too high of PPMs for my set up, but your plants look great. I normally can't get above 700 PPM (EC 1.4) without seeing nutrient burns.. but different nutrients, different environments. Personally I wouldn't adjust anything unless your plants are telling you to. good luck!

Its outside most recommendations in particular DWC which actually needs lower feedings than soil as the nuets are constantly refreshed. Your call as no pics to go on.

Feeding right after repotting (coco coir).After repotting an auto flowering plant I get runoff EC of 800, while feeding water has EC 1200. I guess EC gets diluted (biggest part of coco coir is new). Should I increase EC of the feeding water? I see slower growth but it may as well be due to stress of repotting.
