You want to have at bare minimum 4 nodes before you contemplate topping a photoperiod (and don't EVER contemplate topping an autoflower!). General rule of thumb is when the plant has 4-6 nodes. Good luck!

Yes, it is done all the time. Supplemental lighting is used in greenhouses to increase crop production during time periods with low levels of solar radiation. These time periods usually occur during the winter months, but cloudy summer days can be as dark as some of the darker winter days.

Just giving calmag doesn't make a calcium deficiency go away... you've got to correct what caused it in the first place .... for this little one, I believe it's caused by a nitrogen toxicity as your pH (which can be another cause) seems to be spot on. Once you get a lockout, you can give the plant the whole bottle of calmag and the plant won't be able to get it - because it's "locked out" ... So you've got to flush this plant. For you, growing in 5 gallon pots, that means running 15 gallons of pH'd water through her to get rid of the built up nutes and salts... into the final gallon, put half strength nutes... BUT I think you're overdoing the Flora Micro which has an NPK of 5-0-1 - NOT the NPK you want or need when in flower as it's VERY heavy on nitrogen.... so stop giving this nute at all to her (and I would suggest you at least cut down on it with your other plants in the grow). Plants in flower need a little bit of nitrogen but not much - and your other nutes are giving some to her... but the Micro is overloading her. After you flush, let her then dry out before resuming your water/feed/water/feed routine (minus the Micro!) .. things should get better. And btw, only give calmag once a week... not every time you feed! That can lead to still other problems! :-D The leaves that are damaged now will not be repaired so don't expect that... and you may see some residual signs of the deficiency show up in other leaves but it shouldn't be as bad as it is in these leaves.. and new growth should see no damage ... Good luck!

Hi there If your only giving half the dose suggested Its defo a lack of neuts id say.. Id up the feed dose 👍 Best of luck 🌱

As long as the plants aren't stretching and becoming floppy, they are getting enough light. To answer your question, i would start increasing the intensity of the light a week or two before you flip the plant into flower. Then, gradually pump the intensity up to 100% during flower. It will harden your plant to increased light intensity and could help prevent light stress and light bleaching. I hope this helps.

First two weeks, keep going with grow nutrients......cannabis still needs adequate nitrogen in early flower. Second two weeks, half grow and half bloom. After this, just bloom nutrients until harvest maturity. I have been doing this for 30+ years and swear by its effectiveness.

After looking through your diary. You are a bit low on feed. (Ppm wise) Up it to 600 and push to 7 if needed. But the way you doing now is fine. I don't really see her wanting much. So no full strength feeds. Once given, can't be taken back. But if needs a little you can give. Always best for it to be wanting a little than giving it a lot. Much easier to fix the issue. U going about it great though. Just up the grow + B a little to bring up your ppm to around 700 (including ambient tap) Good luck

Also bei grüße von Pflanzen kannst du mir dem ppm weiter rauf gehen. Denke 750-800 ppm sollten sie ohne bedenken schaffen. Und solange sie nicht sich ein kringeln und zu dunkel werden würde ich mir keine sorgen machen. Meine Pflanzen sind jetzt seit 13 Tagen in der Blüte und ich gieße im Moment mit 1200 ppm und werde bis 1600+ gehen (vorausgesetzt die Pflanzen halten es aus) Einfach die Pflanzen immer im Auge haben und ständig Beobachten um auf Veränderungen reagieren zu können

You've got powdery mildew - a direct result of the humidity being FAR too high... There are any number of remedies that you can find if you do a search for them but the DIY with milk or the like aren't terribly effective. This has the potential to kill your grow within a matter of days so get on it... and get that humidity into the 40s, tops.... Good luck....

Hey Growmie, If you have mites you'll start seeing bronze- or yellow-colored spots on the plant leaves. You may find that the underside of your plant leaves is discolored or that the leaves have small holes. Another early sign of spider mites is finding webbing on the leaves and stems of your plants. If the plant does have spider mites you're going to want to get it away from any other plant so they don't get them, if you caught it early the plant should be able to be saved. But I'm not going to lie it looks more like a deficiency than a spider mite infestation.

She is hungry, My guess is you have a nuturent(salt) buildup causing a lockout. Could also be your PH is out of range but soil is very forgiving as long as your putting the correct PH into the soil. Just looking at your pictures Im guessing the cause of the buildup is from 2 things. 1. Not watering/feeding with runoff( 1/3 should runoff). So if you water 3L of water you should have 1L drip out the bottom. 2. Letting the plant sit in runoff. You should elevate your potters a bit so they don't sit in the runoff because this will cause a salt buildup. To test for to much food or lockout. Your next watering or feed. collect the LAST bit of runoff and compare it's PPM to what your feeding. If its dramatically different then you need to adjust your feed accordingly. If the PPM's are high( PPM + half the amount your feeding.example 800ppm comes out at 1200( 800+400) then you want to do a flush( no more feeding just water until runoff gets back into range) If the PPM's are even higher then that you might want to consider a HARD flush. Add PH water to saturate it and wait 30 min to let the salts break down a bit. Then continue to add water until your PPM's get back into range. ****Warning Hard flush is risky in soil. You can wash away all the good microbes in your soil and cause more harm then good. Soft flushes take longer but are a lot safer. Your using synthetic nutrients so its not as risky as an organic grow. Lastly if the PPM's are lower then you have a hungry girl and should increase your feed with that one. Also check your runoff PH and adjust your water accordingly. But never adjust out of range (6.0-7.0). Always keep the water going in within range and
