    Hi all,
    This is my second ever grow and ive decided to try Autoflower short ryder from Nivana. Since ive started this grow my plants have never seemed very healthy. All the leaves are a pale green, some leaves are beginning to curl at the margins and some leaves have brown spot which i assume is nute burn.
    My plants are approx 45 days old which i assume should be i little bigger at this stage even though they are auto flowers?

    see my grow details below, any help appreciated...

    Growing in coco, using the canna coco range inc A & B, Rhizotonic, cannazym, boost & pk13/14
    Feeding every 2-3 days with half tap half RO water (ph ranging 6.1 -5.6)
    Temp from 75-81, humidity 35 -50, light schedule 18-6, pot size 6.5ltrs.
    Many Thanks :joint:

    Your ph is a little low. so is your humidity and you can try a 24 light cycle with most low ryders. Give it some calcium too

    no. 6.5 for coco 5.8 for hydroton. 6.8 for soil/soiless. Some run it lower but thats the ideal range

    with my PH being to low has probably locked out vital nutes, hopefully this will be the answear to my problems! thanks for the help

    Yer low ph probably give you a series of different nut lock outs, plant looks like it may finish ok but leaves look worrying. At least you got a starting point for the problem with the low ph. Is it advisable to water every two days like you are doing?? I grow in soil and wait till superlight pot till watering, don't have much experience in yourr medium though, anyone else know?

    coco is quiet versitile, you can water it every day if you want or even hook it up to a drip system. I water every 2-3 day by hand, sometimes leaving it to dry out to incourage root growth. Im still a little confusd over the PH, there appears to be a mixed view as many people water between 5.7 and 6.3. im going to try at 6.5 to see if it improves things.

    yeah. Actually your plants don't look aweful for autos, but yeah they'd be a lot better it you didn't have your nute and ph problems. Coco i've come to realize, is as good a medium as the skill of the grower. I mean you have to know how to use it. I didn't the first time and still got some good plants. By the time I got the hang of it, I swore I'd never use anything else for a hydroponic medium. So I don't think it's the coco, even though it binds mag. and potassium. Since your using the canna line, I assume they took care of that.
    You say your using r/o AND tap water...don't do that. Tap water makes you ph jump all over the place, not to mention all the other shit wrong with it. I don't know if you need cal/mag with canna nutrients but usually everyone who uses r/o water need a cal/mag fertilizer. And you already know about the ph, so yeah, that's what I think.

    So beansly what PH did you run your coco at? do you think it would be sensible to give them a good flush and begin feeding them with a PH of 6.5. Ive been trying to source sum calmag. Might have to look on line though as non of my local hydro shops supply it in the uk
