New grower 4th post need any advice

hello to all the growers
i am been posting here from day 1 of this plant you can check it in my profile i am using now light cycle of 12/12 and its been 3 weeks exactly from the moment i turn the switch into flooring mode this plant called zensation 70%indica 30%sativa its say its flowering period its between 7-9 weeks the temp keep between 80 at day and 70 at night and humidty 40-55% i am using now only flora bloom for nutrients with any watering and for the last 2 weeks i will give her only plain water

my question is this :
if you see any issue with it right now or its look ok ?
some leaves turn yellow on the bottom but i think its bc they don't get light ?
do i need to flash the plant when and how ?
please let me know any thing you see as a problem or can help me to be a better grower
REMEMBER ITS MY FIRST GROW




thanks.

wow . this s really your first grow . it loos like somebody that has been growing for many years is growing that plant seriously i see people that been around for many years plants look like they are half dead . well done . i am impressed you must read a lot how to grow .

If you are using only the bloom portion of the nutrients then that would likely explain the yellowing leaves. Your plant will leach out the Nitrogen it needs from lower leaves (causing premature yellowing) when it needs. You still need to give them small amounts of N even when in flower. Too much P/K too early into flower will do this as well. Honestly, your grow looks great, certainly for a first go at it. Good job so far!

#1: When asking what we think and you supply a pic with the bloom lighting running.....We can't tell shit! it's either yellow as hell from the HPS being on or Blurple as hell from the LED being on! TURN OFF THE BLOOM LIGHTING and use normal lighting!

Looks fine from what I can see......Did you start the "only" bloom at the flip?. If so the yellow could be from too much P too early!

Veg foods till week 2 of bloom
50/50 veg bloom for week 3
Then 100% bloom till done.

Go ahead and feed till harvest, won't hurt and will increase yield. Flushing is an old school Hippie myth.

LEDs are fine for vegging but the "blurple" one's lack something in bloom...

I like them also, my advice if this grow finishes successfully is to take good notes of changes you might make on your 2nd and 3rd grow. After a successful 1st grow, my mistake was to try to grow bigger and better buds and that almost always means more of something. More light, more water, more nutrients. I had a successful 1st grow 25 years ago and without the help of the internet or other growers I changed so many things I didn't know what I did wrong and it took a long time to correct my problems.

Your plants look nice from what i can tell. Especially for your 1st grow. I also grow under "blurple" Leds and i do agree with other posters that looking at your plants under natural lighting once in a while will help you determine their overall health much easier. A lot of times the led makes stuff look much different then whats really there. I also agree with Bubba Blend that keeping a written journal is one of the most helpful things for a grower. Great job so far on your grow and i hope you have a heavy harvest.
