1- what do u think about the pictures of last week? (how we can fix our little problems?) *The first thing I'd do is drop the humidity. If you're at like 72 degrees, your humidity during flower should be more like 45% Your nutrient deficiencies/toxicities can't really be accurately judged if your plants are not up-taking the nutrients they need and that is directly influenced by the VPD. If you are not familiar, check it out. *I'd install a heater and keep the differential between temps between day and night more like 3-5 degrees. and if the temp drops, the humidity needs to drop as well or your plants will not transpire properly. Check out https://vpdchart.com/ 2- we ask suggestions for the distance of the lamp LED MarsHydro TS3000 (last weeks) *get the photone app for your smart phone and check your DLI. if you can get it to between 30-60 mol/m2/d you'll be good. As long as you don't roast your buds in heat, you'll be good. usually 12" is about where I start. Check the bud site and leaf temps to make sure. but my DLI is about 45 mol/m2/d and in the 8-9" range and my leaf temps are 78-80 degrees. my tent temps are like 78 with RH of 50%. 3- we should do an other defoliation? *I'd remove any fan leaves that have a stem longer than a half inch or so. Leave anything you can't easily snip at the stem. 4- what about flush? :pray:�:alien: I personally do not flush at all. I do ease way back on the Nitrogen during flower. The plants tend to need less water when they are in flower for me. I keep track of the weight of my pots and water before they feel light, but If I can't pick it up easily, I don't water until the next day. I'm in coco, so that's different. Either way, it goes back to VPD. need the plant to uptake properly so you know when the soil is getting light on nutrients. *Use a bloom booster once a week to bring you P & K up. Your flowers will thank you. Just my 2 cents, good luck!

nice grow mate!!

Thanks for choosing our strains. Good luck and we hope you enjoy it. If you have any issues, please let us know. :green_heart::grinning:

Just my 2 cents, but your humidity is super low for the temp you're running. if you're about 77 degrees during the day, you should be at least 65%RH. Your Vapor Pressure Deficit (VPD) determines how your plant will uptake water and nutrients. if the balance is off, you will see deficiencies and toxicities because the plant isn't uptaking the right nutrients. also, consider bringing your pH down to like 6.0 or 5.8. Cannabis likes it on the acidic side, that can affect uptake as well. Try using vpdchart.com and put your values in. It will tell you what your kPa is and in flower should be between 1.1 - 1.5 kPa. your values bring about a 1.78 kPa measurement and that is waaaaay too high. This changed my whole life. I'd also consider running your nighttime temps within 3-5 degrees cooler, tops. I run my heater at 77 degrees at night so it's only about 1-2 degrees warmer during the day with the lights on. I would fix anything environmental before I adjust my nutrients. :)
