I have autoflowers in coco coir 70/30 both same issues light green leaves from 1 week, start feeding with nuts after 7 days of germination.

also have another plant which is only 1 week old and i wonder if i can swap from GH nutes to canna coco a.b i have them and want to see if any difference in using different feeds and nutes ill follow the chart canna recommends just half dose for beginning but i have feed them 3 times with GH nutes and now will start using canna if thats not damage my plant changing nutes ?

ussing Ecothrive Coco Lite just done first run off and its showing ppm 620 EC 1.23 ph 6.4. but done this flush after 2 hours of feed. i use Lucas formula with GH nutrients.

Which brand of coco are you using? She's most likely just hungry. Do you know what the PPM of the runoff is?

maybe its overwater because i didnt know how to feed water in first few days of germination so did 500ml and then 250ml in that week but now i start to do on time every 2nd day what i should do dont know because its first time for me....

ph its between 5.8 - 6.2

so my feed schedule will look like this i only feed second time and want to start feed them every 48h

so 3 gallon fabric pots

per 1 gallon water

cal-magPlus - 2ml

micro - 1ml

Gro - 1ml

Bloom - 0.5ml

Super rootz - 4ml

first 2 feeds 250ml per pot and will increase every feed maybe by 50ml of water ?

light is spider farmer 2000 and keep 30inch away and on 100% light, got fans, humidifier, heat tube, etc, just done the proper setup, but this happened not sure why this happening i feed second time with nutrients after 7 days from germination and this second time yesterday with calm-mag plus for the first time because just received it just now for first feed i done with all GHE Flora Series trio with super rootz 0.5ml/1l so its per 1l - 0.5ml cal-magPLUS, 0.25 micro and gro, 0.025ml bloom , I was thinking maybe nitrogen issues not sure at all ? how long it takes when plants show some changes? i feed 250ml water with nutritions in 3-gallon fabric pots, and start do it every second day or every 48h
