Pls can someone help .on one plant leaves start to change color.
that plant is under Hans 180 W 45 cm away .I add nutes at day 32 0,5 grow +0,6 bio heaven+0,5 sensi cal-mag.I spot that change at day 36 but i dont think thats nute burn .TY
First of all, you are watering too much, I mean 1.5 liters per day? That should last the plant a week. Now let's check the rest of your info, your pH is spot on, so is't not that, your lights on temperatures are good too and so are your lights off temperatures and your humidity.
Now in the picture you mention the only thing I can see are dark spots / stripes on the leaves, that usually happens due too much nitrogen. You see although your feeding was not too strong, you need to remember that you are using 18 liter of soil and that has a lot of nutrients that will carry your plant for a lot of time, for example I use 11 liter pots and that lasts me 8 weeks before showing a slight deficiency and only accepts a slight cal/mag additive to compensate for soft water (usually 0.3 cc/lt which amounts for 90 PPM (1.8 EC).
In short stop the feedings of the plant is not showing any sign of needing it, I would wait at least until week 10 to start a light feeding, and get an EC / PPM meter it will help a lot in measuring how much to feed.
58 days old(20 days at 12/12) .3 plant show sex after 7 day at 12/12. One plant dont show sex yet, 20 day at 12/12 no pistil .What to do , wait little more or i have place out side in garden but i dont now if that do some stress she is 20 dys 12/12.
Hey dude, If you are referring to the plant in pictures 11-17 then she is suffering a P deficinecy seen it before fixed it by increasing PH to 6.5> and adding more bloom nutrients and/or a bloom booster. Looking at the size of her she could probably take more than what you are currently feeding... good luck, let me know how you get on:v::skin-tone-2:
So there are a few things that could cause this but most commonly it is due to light leaks or an excessive amount of nitrogen. Cut back on any grow nutrients and focus more so on nutrients meant for bloom. Also you could adjust the light schedule temporarily to a 13-14 hours of darkness. Double check the flowering areas as well on the off chance you may have a male plant which produces small pollen sacs. Good luck on the grow.
Hi there! Indeed this is weird... I'm assuming your nutrients informations for week 9 are wrong? Such heavy doses would certainly create a nutrients burn + lockout for weeks. Since your plants look healthy, let's dig into other possibilities. I'm also assuming you already made sure this was not a male, and I don't see bananas on the pictures. Do you move/switch the pots inside your grow room? Was this plant at the same place for the last weeks? If so, she may suffer from not having enough light, resulting in late flowering compared to her sisters. What spectrum is the lamp currently diffusing onto this girl? Keep us up-to-date and happy growing
