your plant is hungry
see those stems .......they are called red vein they happens when the plant needs N P K one of those in this stage of life the plant wants N and K
the brown spots odds are that is calcium def


1 check your plants PH lvls ......in soil u want 6.5 if to high or to low causes lock out (plant can not intake what it needs)
u look to have a air pot ......take a gallon of water PH it to 6.5 and pour it tho u want to use a shot glass capture some of the water that leaks out the bottom and test the PH ....it should be 6.5

if that checks out u need to increase the food u are offering to the plant
what are u currently given it

Thanks for the reply
But as I said in the post i use coco ,my ph in run off was 5.9 and my ppm was 650 is it enought?
Is it weird?this spots appear in the middle growth and not from the older leaves ....yesterday they eat adout 660 pmm 1 gallon of water each

well coco i never done ......dwc i have
your ppm is low the plant is telling u that with the slow growth and red vein
as for the leaf that is your old growth it looks to be one of the first leaves u said only 2 node

i did not really go on ppm other then to see how much it had taken up mid week .........increase your grow by 3 mls a gallon your micro 15 mls total add in rapid start (fallow the bottle)
if the dots keep showing then u are running a cal hog plant u will need to buy some calmag+ or something like that as the micro is not enough

u need to make that red vein reverse as it does the plant should grow much quicker .........the rapid start is the best rooting compound i have found in 5 years of experiments it will increase the root mas allowing better up take and bigger buds ........photo plant will take 5 to 7 days to see....if not enough increase the grow another 2mls a gallon

Thanks man I will wait to dry a bit and I will increase dosage.
Advanced nutriens suggest for ph perfect COCO nutes not to use any cal mag source because they had already and second it gonna damage the PH buffer!!! to be honest I am very excited because I never adjust ph and my run off is always 5.9!!!!but if this problem continues I have to add some call mag source for sure.for rooting compound i used voodoo juice stopped 1 week before as program suggests.the damaged leaves is in second node there are one node above and the fan leaves have no problems

I will try to get my ph in the 6.3-6.5 range is good to fluctuate ph between 6-7. Also check ur ph meter it may need recalibration. Your problem looks like lockout, plant can't uptake the nutrients. GL

wow man it's simple....you don't need to check your ppm....stop that. you need cal mag...and feed her some nutes...people on here make things way to complicated..

word of advice if you're gonna be on riu, don't do anything to your plants till you get a few opinions....some people just can't grow but like to participate.

Thanks for the advise.as I said advanced nutrients ph perfect for coco sais not to use any cal mag source they gonna mess up the PH but if the problem continues I have to add a cal mag source ...This confuses my a bit.I giving them about 700 ppm with 10% run off do should feed them more?
