My first indoor HELP

try raising the light higher, maybe the leaves are getting burned

Hey buddy. I went through the exact same thing as you a while back. I recommend a root wash with pH 6.5 and then measure the runoff water until it’s 6.5 again. After that, apply flowering nutrients and stop using the nitrogen-rich fertilizers. You should use a fertilizer with an NPK ratio of 1-3-2 to help with the start of flowering, and also use half the dose recommended by the manufacturer. Cheers homie and good luck with your girls!

Defenitly need calmag.

Congratulations on getting into growing cannabis & joining our community! I will gladly help in bullet point form what I can see & will also reference you to our tutorial series here on grow diaries. We also have it in video form on our youtube page which is linked off of our main grow diary profile. We cover very very detailed step by step day by day all the way from seed to harvest to dry & curing. Now lets take a look at a few quick things that need improvement : - Your humidity is too high for your temperature. When we grow, We think of the 2 basic set points temperature & humidity. But when those combine they form a 3rd, Most important set-point. VPD, Vapor pressure deficit. We need to make sure our temperature & humidity line up to make safe healthy VPD for which stage of growth our plants are in. Read & study this link, Print off this chart and use it daily. Log your numbers : https://cerescann.com/importance-of-measuring-vpd/ - Your PH has fluctuated quite a bit from early on & later in growth, We want our PH balanced & dialed in consistently through our crop it is very important. Here is a great illustration and article about how PH affects our plant's. It is on an autoflower website, But this applies to all Cannabis plants. : https://autoflowerseedshop.com/cannabis-ph-chart-guide/ - When we are growing, We want to follow a routine when it comes to feeding or watering our plants, We do not want to feed every single time. We can either do FEED / WATER / FEED, Or FEED / FEED / WATER. This helps keep salt build up from forming up on our roots and helps our plants grow along more healthy & make better use of the nutrients you are giving them. You are going to want to get a basic feed program of GROW / MICRO / BLOOM. This is called a 3 part feed, We use this as our basic nutrients for our plants. It is completely possible to grow a good crop with these nutrients alone, But most people then will add in flower enhancers, Root growth enhancers, Things like that. We cover basic easy nutrient programs and how to use them as well in our series. It looks like you have done a lot of good things with your plant's training techniques, I feel once you understand and learn the environmental and feeding aspects you will see a big improvement in your next harvest ! Please take the time to watch our tutorial series & check our the diaries that go along with them, If you have any further questions PLEASE do not hesitate to ask me. Keep it up & do not give up!
