First Ever Grow

Yes the tips of the leaves doing that is sign of toxicity. lessen up on the N in your feed and it will stop happening, but the existing damage is already done and nothing can be done to fix it on the older growth. Only will be fixed on new growth. Good Luck! ***disclaimer, multiple people are answering all questions as there is a contest called GOTM, when a user is selected as the answer they get a point.

Se n ai pas bien grave et je pense à se stade La plante va utiliser l azote (il n y a pas de brûlure à l extrémité des feuilles chose qui arrive en premier en général quand il y a sur fertilisation ) Et la forme des feuille vient du fait que c une grosse indica tu verra quand la plante aura une semaine de plus les feuilles seront normal ..je ne te conseil pas de faire un rinçage achete un testeur ph / ppm et quand tu prépare tes nutriment tu vise (à se stade de la veg ) entre 600ppm et 800ppm poyr un ph de 5.8 à 6.2 max en vegetative après e floraison tu peut monter à 1200ppm et 6.5 ph voilà en espérant sa va t aider n hésite pas à passer me voir si tu a des questions

Yup, you're right, it is a nitrogen toxicity but I was puzzled as to how this occured because between the Grow Big and the Fish Shit, you're really not giving it too much nitrogen at this stage of growth... but then I saw how much you were watering them and the answer came... You're growing in a 5 gallon and only giving them 1/4 gallon of water/nutes a day - all the nutes are stacking up in the soil and THIS is what is causing the problem. When you give plain water, you need to make sure you get at least 10-20% runoff... this clears out the soil of excess nutes and salts (not ALL but just the excesses that are building up). In a 5 gallon pot, I would be giving them double the liquid you are giving them per day. I also, whether watering or feeding, put a saucer underneath to catch the runoff and will let the pot sit in the runoff for a good 15-20 minutes - that excess water or nute solution is usually soaked right back up into the soil and if it is, I give the plant some more... I keep doing that until the liquid is no longer being soaked back up and then dump what's in the saucer because you do NOT want wet feet! Make sure you let the soil dry out completely before giving anything more. What you need to do is to clean out the soil with a good flush.... for your pots, that means 15 gallons of pH'd water through each one with 1/2strength nutes in the final gallon... then let it dry out before watering them again ... This should take care of the issue and those lovely lookingi plants should be much happier! Good luck!
