    Default Nutrient Burn and Nitrogen Toxicity

    Hi,

    My little girls are a month old and have Nutrient Burn and Nitrogen Toxicity badly. All they are in is biobizz allmix and just had plain water using wet/dry cycle. Environment is right and under 600w light. I was thinking I can either

    1) Flush all with plain water then feed with 1/4 strength biobizz fishmix.

    2) Flush all with plain water and wait until they need watering again then feed.

    3) Carry on and leave them to use up all nutrients in soil.

    What are peoples thoughts, option 1, 2, 3 or something completely different.

    Thanks for your time it is much appreciated

    This is the worst one out of the lot. Stems are purple and some leaf tips pointing down.

    What size pot mate? Tbh the new growth looks healthy. I'd just stick to plain water for a bit if I were you.

    Also she looks a bit leggy and slighty over watered. what lighting are you using?

    What are the feed levels? The stems are purple as hell, which isn't very often down to genetics.. How far away is the light your nodes are quite far apart? Is it a 600w HPS/MH or LED?
    If only I grew cannabis as well as I do corn

    Not sure on pot size but was letting them root out then going into final 11L pots using a 600w dual spectrum.

    Not feeding anything just using plain water. They are in biobizz allmix. The light is about 3 ft away and using 600w dual spectrum.

    I'd move the light a little closer if temps allow you to.

    There load of ferts in the allmix from biobizz. Stick with plain water until the new growth starts to lighten in colour, then add quarter strength grow nutes. fish mix isn't great in the soil more for folia feeding.

    How regularly do you water them? I'd give an extra day inbetween watering to let the soil dry a wee bit more.

    The burns on the lower leaves are just the plant adjusting to the all mix soil. The clawing is over watering and a bit of adjusting to the all mix.

    Also what's your light schedule?

    What's your temps?

    Cold temps will also cause your plant to stretch for light and become leggy, try and get a nice steady 26 degrees lights on and as close to 22 degrees lights off.

    Thanks for the reply.

    I water whenever it feels like there is only about 20% water left.

    18/6 temps between 21 and 28 degrees.

    That's quite a big swing in temp, that will explain you stretching and probably why you plant stems are purple.

    Maximum difference in temp should be around 5 degrees. The closer you get those temps the closer the nodes stay together, giving you fatter more dense buds.

    I'd say you watering is fine and the clawing is purely down to the all mix soil.

    Btw I'm only offering advice, I don't claim to be a know it all bit I've seen and had these symptoms before and correcting them helps your final product for sure😉
