Hello this is my first grow … iam about 2 weeks in …
recently ive noticed some yellowing and drooping in my plants so i changed the reservoir but no changes happened
Kindly help me out with an appropriate solution
Iam keeping the ph in between 5.8 -6.3
ppm is 500-550
lights is kind led xl 600
Light distance is 38 inch from canopy
temperature is 26°C lights on 23°C at lights off
Humidity is 50-60%
light cycle is 18/6
Nutrients used are flora trio by general hydroponics and cal mag by general hydroponics
Welcome to the forum. Pictures in natural light would help.
Ill assume the green tube is for an airstone? What is the water level in the bucket?
Yes sir that is for airstone
Water leval in buckets is about 10 cm below the net pot

Have any roots entered the water zone? Or are you top feeding still?
Can the problem be due to the high water height ?
yes thats possible. The idea with hydro is the root zone has the upper portion in air and the lower portion in solution. If the upper portion is in solition too you can suffocate the root. I wonder if the new growth is healthy, will it stay that way and continue that way? In the beginning your plant had to transition to the solution from the net pot, that may have been stressful time for it? Niw that it is in solution it may be alright? Perhaps be patient for a day or 2 and see if the problem persists? Hydro can be finicky especially when you are learning. So expect some challenges until you get dialed in. Maybe even a loss or two?
And this is the same reason the leaves are turning yellow at tips ???
I hope this isnt a nutrition burn ?
How do you measure you pH? Are you using strips or a meter? What is the PPM of your water before nutes? Did you account for that? Tap = 250 PPM so add nutes and subtract 250ppm (in this example) to get actual ppm of solution.
It also looks like the beginnings of Magnesium deficiency. Here is a picture of it.
If you have a mag problem you could add 1/4 tsp per gallon of Epsom’s salt to fix it up.
Brown tips often means nute burn, but at that low of ppm I would be surprised.
Using a ph pen … the ph has stablised at 6.0 since yesterday
Ppm of water before nutes is 22 as iam using r.o water
Iam already adding 4ml/ gallon of cal mag should i still add epsom salt ?
Ppm stablised at 534 …
Can the state be of underfeeding also ?
Iam using a 30litre reservoir for each plant though
Also one more thing … i somehow feeel that just after light off period my plants seem to be less droopy
RO, you need Calmag.

@Member420 already putting 4ml/gallon of cal mag from general hydroponics should i increase the amount ?

@Cg007x calmag might be a little light depending on the vendor. I use True Cal-Mag which is double strength of GHE Cal-mag according to the literature. I tend to run 4-6ml per gallon of water, sounds like your at about half of what I run, if we believe the websites. On the GHE hydro chart I see 5ml recommended, if the docs are true I would run up to 5 to 9ml of GHE CALMAGIC based on my other product and claims. If it were me would increase the calmag a little on next watering, not jump to the levels i use as i have a ton more light. I always add calmag off schedule of the other nutes (calmag on water only days, 1/2 to 3/4 strength nutes per gallon Tuesday Thursday Saturday) armor si as needed to raise Ph after initial dose.

Sounds right, 4ml should be enough.
Wow alternate feeding … i did not think about this also never read it anywhere … i will try this
