1920 PPM Hydroponics DWC 4th Week Flowering

versace_growstarted grow question 5y 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.

Coco grow: the EC of my runoff is consistently 0.2 mS/cm lower as what goes in (1.1 in at this time, runoff is at 0.9). Also, PH of runoff is at 5.8, while 6,5 goes in. Is this a problem? What causes this? Its been 8 days since germination and they look healthy.

Nutrient burn?I believe I overfertilized this week. I am using a four bucket DWS system with Reservoir bucket. This is the last week of my veg and I might’ve been heavy handed with the fertilizer. At one point my solution was 1844 ppm. I usually run itbetween 8 to 1200 ppm. I delutedd the solution in half. I didn’t have time to change it all because the lights are going out. Do you think this is nutrient burn? Thanks

Hydroponic PPM and feeding. How do I match magnesium sulphate to potassium for flowering??Do I got this right? Hydroponic Flowering cannabis eats at a rate of 1-1-2 and for maximum useage, feeding 1-1-2 makes sense. Extra nutes outside the ratio is wasted and extra. You want highest PPM possible before burning. Will extra Cal-Mag burn roots/leaves?
