The taller plant still has leaves getting darker and the pots have built up a white substance on the outside. I've reduced the nutrients, changed to watering them ever other day and switched to using distilled water instead of my hard well water. I did notice a decrease in the PPM in my runoff but it is still high. Still looking good but small. Trichs are starting to get cloudy, maybe another week of nutrients then a week or two of flush? we'll see!

Hi there! Cool looking setup and plant you have here! A few things that I notice....first, you have a canopy that is pretty open -- you should not be having any issues with light penetration here. Second, I agree with Bulbi that you have a low output light. HIDs are great and often better performing than LEDs, but 150W is not a terribly powerful light. You might have better success with a cheap 300W LED in terms of coverage and output. If you want to stick with HID, you might want to consider upping your wattage. Thirdly, I notice in one of our photos that your room temp is around 72/73 degrees F. From adjusting my environment the past year, I've found that keeping your environment closer to 80 degrees F is usually better -- plants tend to respond better. You also need to balance out the light distance -- if you have a cheap laser thermometer ($15 on Amazon), you can check your canopy temps. I usually shoot for around 78 degrees at the top of my canopy. That will help you determine if your light is too close or too far. While 72 degrees F might produce a plant, it's not usually ideal temps for a plant that most frequently grows naturally in high temp places. I'd say adjust your room temp to get it a bit warmer, and look into a bit more power for lights. You could even consider getting some warm (~2700k) lightbulbs to help you get a bit more light for this grow. Best of luck! Let us know how things go!

Anyone have a guess to whats happening to the leaves on the taller plant? is it light burn or nutrient burn? or is it normal for the leaves to turn a dark purple when late in flowering? The short one is showing no signs of this & the only difference between the two is the height.

Hello @Grow413 ! That's a humidity stress not because the value of RH that you have is wrong (especially for the flowering stage ) but because the 40% RH in combination with heat gives a slight high VPD. So it's a heat problem that is expressed through humidity stress symptoms. Tow options you have. First option is to raise the humidity at around 50% and the second option ( and best to do ) is to lower the temperatures at around 22-24 °C. If the lamp is the reason for the extra heat that you have ( 25 cm is very close to the plants ) then raise it. Happy growing ! :facepunch:

I would raise the light 4 inches and switch to a 10-14 light schedule it wont be long before they start fox tailing the more fox tail your thc starts dropping u will lose taste and smell think of it as you going get a bad ass sunburn i would reduce the light raise it and just soon cut off those leaves at this stage it really doesn't matter :+1::+1::+1:They taking more energy from the plant :+1::+1::+1:

@MUDBUG, yea? I’ll give that a try. Is that to just put more focus into the buds?

@Grow413,Yes it does waste energy trying to fix itself those leaves will die off turn all ugly up there u dont need em :+1::+1:

@ValhallasGarden @MUDBUG @mad_scientist So my problem with the light is that its already as high as possible in my tent. I could dim my light down from 400W to 250W if that will help? If not I'll try changing to a 10/14 light schedule and I'll bring the RH up a bit and see if that helps.

I'm using Plagron nutes for coco but I've yet to purchase the Green Sensation since its a little pricey so when I went into flowering I just upped the amount I was giving them.

@Athos I thought I was overfeeding as well since the shorter plant has the dark shiny leaves too but little to no yellow tips yet. So I've lowered the nutes and switched to watering every other day.. waiting to see if that helps. And yes I know, sorry about the lighting!

Thank you all, I appreciate the advise. This site has been amazing!

@Grow413,What you can do is to supercrop the tallest branches of the taller plant.

@Grow413, You can try dimming the light if you have a digital ballast other then that im not to sure , you could get a cool tube that will help alot , but its like 120 $ .
