Did you buy the add on for the app for the type of light you have? The full spectrum led add on seems to work petty good for me, but the t5 add on not so much seems to read very low. Also don’t take light reading with the tent door open you lose a lot of reflection.
I think this is the point that @Docnraq was making. Don’t let these high tech techniques and meters be your rulers. You will be better served to learn how to read what your plants are telling you and not so much the meters. For example one of the first signs of light stress is the top leaves canoeing. When you see something like this then use the meters as tools to help troubleshooting. Also this is a good way to double check your meters. If you are seeing heat stress and one meter agrees and the other doesn’t, well you know which one to use.
I didn’t notice that, but you have a very good and honorable reason.
Betting things will improve tomorrow!
Thank you I also have looked at that diagram a few times and I was going to bring it up and I completely spaced it out cuz I have so much in my head so at about 37 and a half percent power I am pushing 532ppfd and 35DLI at a hanging heights of 20 inches. Now when I look at phlizons chart for seedlings let’s say. I was under the assumption that the pepper ppfd range is 100-300. If this is correct than something doesn’t line up somewhere. At a 2ft height and 37 percent power my ppfd is in the veg range of 400-600. If I was to go by their charter and their power recommendations and assuming I’m using my meter correctly I’d be frying my plants. So after all that is said and done is my meter not calibrating properly or is it manufacturer have a different ppfd range for veg and seedling and so on. You guys follow me on this what I just talk a circle around myself. I still haven’t smoked
I really like that advise. Never thought about it that way until now. Thank you
Is this the canoeing you guys are talking about when it has too much light I don’t know if you can see it very well
Looks like this. Although this is a super extreme example. It looks like it sounds. Leaves will begin to cup upwards, downwards would be a whole different issue. That lady has some new growth! Not too much sufferage from all that nitrogen. The lil extra water paid off.
Techniques like vpd and dli are about the minutea. Fine tuning of the basics to fit your specific environment.
@Djh1984, That is a interesting and confusing situation that you have. When looking at your pictures I see some signs of heat stress, but the stretch of the plant would indicate a very good light level for a plant that size. We will get back to heat stress signs.
This what I think is your issue with your lighting. I see that you are not in a tent, and the walls are fairly far away from the plants. Also the walls are not very reflective. This situation is causing you to overdrive the light when trying to obtain the correct DLI. The 18 - 24 inch recommended height is based on testing done in a tent. You will need to be more like 30 - 36 inches so that there is not so much heat hitting the plant.
You will get a much better return on your investment if you can get some better reflection. Even if you just use some temporary type panels that you can place around the plants.
Good rule of thumb put your hand at canopy level under your light. Hold ot there for 30 seconds, if its too hot for your hand its too hot for your plant.
@Docnraq, Good picture of canoeing. Kinda early out where you are isn’t it?
@Djh1984, I think Doc has you covered on canoeing. Another sign of led heat stress is the weird looking patches on your older leaves. These psoriasis looking patches start off looking like little yellow spots. They resemble calcium deficiency spots, but the calcium deficiency spots stay contained in the leaf’s margins. The heat stress spots will not be contained in the margins.
As you make adjustments and move ahead the damaged leaves will continue to grow, but the damage will not go away. For this reason the majority of your focus should be on your new growth.
Meh about 9am now. Donation left me messed up yesterday, ate a few edibles before bed and even after coffee still cant see straight. Gonna need to hydrate today. If I was a plant id be this.
Crafty way to give a lesson on when to water. Or at least that’s what I gathered.
It is. A day or so before this would be better. If your plant looks like this any microbiom that existed in your soil is dead or dying. Even still, if you watered her, she would be back to good in a couple hours. Can always reinnoculate your soil with microbes and fungus again.
Always enjoy learning and will always appreciate it. I have been thinking about knocking the one pineapple downto the 3rd node she stripping her up to it. What am I watching for to know that she ready to handle it. I really wanted to shorten get up tonight but managed to keep off her. I always got tomorrow
Happened to me too. To be honest in my first grow I wasnt gonna top but my ol lady was doing some training and snapped two tops.
Go for it. Im big on gut feelings. Your plant is talking to you. She either wants you to learn or she wants you to help her get looking a certain way. Be prepaired for potential shock. Its not a gurantee but always a possibilty. With photos its not a big deal just pushes your harvest day back a lil.
Can you help me, I would like to know what these black spots are and how much longer to harvest? This is my first grow, plants are Blue Cheese feminized, are about 7’ tall, grown in my fruit/ vegetables garden. Black spots don’t appear to be bugs?? I haven’t seen them move.
Any advice will be appreciated.
I can sure try 
The spots are alittle concerning. Could be a couple things. 1) bug excrement, I dont see any other sign of them but I would do a bug check look under leaves and look for more damages like this
2) fungus. Leaf septoria or Altenaria.
This seems less likely but always a possibility. Look for more spots or for things to get worse.
As is, Id ont see alot of a problem. Its either nothing or just getting started. Look for more. Also can you wipe the spots away?
A while yet. Flowering USUALLY takes 8-12+ weeks. And you seem very early 2 maybe 3 weeks in. Did you record when she started to look like this. (A pic of one of my plants at week 1 of flower)
Yellowing of lower leaves is normal early in flower so dont sweat those. You should remove them though. Your plant is beautiful. Excellent work so far
Thanks Doc. I kind of thought that it might just be excrement. No damage to the leaves like you presented and I will try to clear away the”spots”.
Unless I’m mistaken, my girls started flowering about 3 weeks ago. This is my first grow so I check them every day sometimes twice! They have been enjoying outdoor living since early June. It may just be they are waiting for less sunlight and temperatures to drop at night?
I have been removing the yellowing leaves and I assure you these girls aren’t coming down until I see amber pistils and a few trich’s.
I really appreciate your quick response. You sure know how to help us newbies.
