Are my plants too close for my new light

to throw my two cents in while i'm bored at work i would say it is hard to actually have too much light. when you see problems from lights being close or whatever it is usually either the heat itself that is the issue. this you can easily determine by taking the temp at canopy not ambient tent temperature. the 2nd reason plants suffer from "too much light" is other environmental facors are not dialed in thus the stress of pushing the cannabis plant hard means the medium and the vpd and the c02 and nutrients all need to be perfect as the plant is gobbling al that up at an accelrated rate. i am not explaining it well here but binge on some doctor bruce bugbee videos. he is a university research scientist that has been researching light and plants including hemp over 20+ years and has shown some good reliable data. in a nutshell cannabis can thrive even with 1800 ppfd maybe a lil more i forget but it's high af. what he shows though is this is only possible in the perfect environment. in other words how much light your plants can handle without looking fucked up is how dialed in the other 8-9 factors are, just adding c02 doesnt fix that issue. all factors need to be perfect to push a plant that hard

your plants look great to me : ) good job so far and good luck. that said idk how the temps are not thru the roof in there lol you are not even usignthe cool tube. but atm it looks good.

Currently I believe I am in the end of week 5. I went into flower at the beginning of last month. So around 37 days from start of flower. I took them out of tent to show yall why I am concerned mostly because my only other grow before this was hydroponic and my leaves never changed color last grow but I was on a 400 watt not a 1000 watt. I am curious if I should be watering more because I only water 1 gallon every 2 days.

if you are in soil now and hydro before and you more than doubled your DLI aka quantity of light daily then a cpl things could be at play based off my previous post even. it is not possible to dial in soil per se so any excess or deficiencies will be magnified when pushing the plant that hard. for example a plant may not uptake some of the nutes it needs because one other factor is not perfect like not enough c02 for the quantity of light, thus the light is in excess for that circumstance. other examples based of the same premise would be a plant could need more N than it can uptake or if N is in excess it is uptaking it too large of quantities compared to what the other environmental factors are allowing it to process since you are pushing it so hard light wise with one of the other 9 factors being off, even if the medium is close to perfect.
i could go on but there are a million reasons to have the disparity between the two grows you mentioned. it could also be as simple as slightly off ph of the soil which can be harder to measure precisely in soil or hard to adjust if already out of whack. i would also add your leaves should always change color it is called senescence and if you pulled with all perfect leaves then you pulled too early in all likely hood last time. many ppl fool themselves into thinking a plant is done by forcing the appearence of senescence by flushing. imho tho i havent done hydro in years i would recommend not flushing until senescence starts. to me senescence is more dramatic in soil for whatever reason. it is way harder to maintian utopia in soil for long periods of time where as in hydro you dial in every feeding. you are spoiling them in hydro in some sense. advesity builds character in ppl and plants :)

Damn brotha that's scientific and I really needed that. I definitely pulled that last grow too early but it was running on 12 weeks of flower with no sign of anything changing and I rushed it.

thanks but to be honest i am mostly paroting dr bugbee and probably very poorly. you like science watch his vids because i actually struggled to effectvely make my point i felt, but thanks for reading thru my rabble and finding some use :)

I recently got a 1000 w adjustable hps light that can be either 400w-600w-1000w-super lumen l. I had to move the plants into a closet though they were in just under a light in a spare roomView attachment 4565435

My setup with a 600w hps I have an 8inch fish line hanging of the mogul socket with a tiny nut at the end

8 inch under the 600w gives me the max Lu without the cooking I get that 60k plus Lumen

by leaving a temp gauge at leaf height for 30mins and adjust accordingly (the best being 8 inches)

I also have the light bulb and socket on a counter weight that slides up and down to suit ...as they grow

is much piece of mind ...so why not you??

good luck
