    Default I look for help from someone more experienced 3rd grow,1st time with led

    Hi fellow growers !!



    After many years i decided to grow again. I have tried to grow 2 more times one outdoors and 1 indoors.
    So i bought 4 seeds,(northern lights, white widow, critical kush, og kush) and on 5th of novenber i had them sprouted and put under 2 laputa ufos 150w and 1 galaxyhydro 300w.

    Apart from Critical Kush all the others and especially the Northern Lights they are not growing and showing signs of dunno what .

    maybe the 2 ufos where too close (20cm 8in)each one was over the NL and OGK but this is not light bleaching .Or it is.
    the galaxy hydro is at (55cm 21in) over the ww and crit kush

    So my info.....

    Soil or hydro or coco DWC
    plant age: 4WEEKS
    pot size: 4GALLONS
    has it been repotted? and when?:
    soil type:
    nutes or additives used and how often for soil:
    Air temps (max min): 26 18 c 79 64 f
    Res temps (max min) 23 17 c 73 62 f
    humidity:45
    lighting type (hps, led, cfl)LED .2X 150W LAPUTA UFO . 1X GALAXYHYDRO 300W
    ph level: 5.4 6.1
    EC (hydro and coco only) PPM AT 0.5 CONVERSION 800-900
    Background EC. TAP PPM 215 .WAS DOIN HIGHER PPM AND I DROPED AT 800-900 CUZ I AM AFRAID I AM BURNING THEM .
    feed schedule and nutes (for hydro and coco) GH FLORA SERIES +PIRANHA+REGEN A ROOT

    anything else you think may be relevant!
    All of them apart from the critical are not growing . Their roots are not growing also . The critical is getting a higher feeding at 1100 ppm and is doin better from all as u can see.

    At the first pic u see them all .
    Bottom left is critical
    Top left is NL
    Top right is OGK
    Bottom right is WW

    Even the critical shows some signs of dunno what on the lower leaves.It has been fimmed yesterday also.Do i feed ger more or i cut down ?

    I would rly use any help. If i messed up and they are a dead story then its ok .But i really want to know what i am doin wrong cuz i find this whole thing very interesting and in my country it is difficult to find other growers and exchange info.
    Thx

    Any chance of converting your PPM to EC as there are many PPM scales & I don't know which one your meter uses

    Old growth looks a bit burnt but the new growth seems fine.

    Try and keep your ph at 5.8 for now and res temp no lower than 19.

    0.5
    i had found somewhere the chart.i will look again
    but i use 0.5 conversion . My hm ap-1 uses that and the General Hydroponics schedule uses also that.

    Your meter is using NaCl PPM scale... see below

    TDS NaCl
    NaCl is a conversion factor based on Sodium Chloride (regular table salt.)
The conversion factor range is 0.47 to 0.5.
Non-linear meters based on NaCl typically use: 0.5 x the EC level (if converting from µS to ppm or mS to ppt) or 500 x the EC level, if converting from mS to ppm.
TDS 442™

442™ or Natural Water™ is a proprietary scale based on properties of naturally occurring fresh water. The 442™ part is an abbreviation of 40% sodium sulfate, 40% sodium bicarbonate, and 20% sodium chloride.
The conversion factor range is 0.65 to 0.85.
Non-linear meters based on 442™ typically use: 0.7 x the EC level (if converting from µS to ppm or mS to ppt) or 700 x the EC level, if converting from mS to ppm.
    That's enough to make my head hurt

    Just stick below row 7 on the chart and you should be ok.

    Any signs of burn back off.

    If the leaves start to go pale go up the scale.
