Double or nothing [first time]

Hi! According to the manufacturer the recomended brightness is 50% for Germination, 50-75% for Seedling stage, 75-100% in vegetative grow, and 100% in flowering. With this information in hand, I would suggest something between 60-100%, maybe 75% or even 100%. I personally believe that 100% is better than 75% during this period though.

Hi! I have no experience on root rot but what I've read it affects your plant quite fast, so you will now if you have it. If the top part of the soil gets moldy you can just mix it up to kinda remove the mold and you can add something like perlite or clay pebbles on top to prevent this from happening. It is not that bad thing if it does not get totally out of hands

Hello @Kazhox ! Technically, that's LST right there! It's simpler than it sounds, and sometimes that's what creates us doubt. The plant looks very healthy too, you're off to a good start 😉 Good luck with the grow

it's from too much Calcium.. older leaves show excess.. Newer leaves show deficiency. Adding calmag when you are already adding calmag can't help because that's kind of exactly the opposite of what adding CalMag is suppose to do.. Less is more.. Cut out the Cal-Mag.. Possible even look at halfing your nutrient ratios.. are you in soil? if so soil has enough stuff to feed your plant for quite some time depending on soil conditions. I hate CalMag because it solves peoples problems and they think it's calcium/magnesium when 90% if the time it's PH.. your Trio formulas from most companies has everything cannabis needs to grow.. Why add it if you don't have too? why buy another product when it doesn't really do anything? add a tiny amout more floramicro if you really need more calcium.. Read your bottles..
