Well had to remove s shell from seed, fucked it up ;p. Looking retarded, but it's some. Bigworm so In culling it.
Got the other garden going aswell. Hope everyone had a wonderful 420. I know I did.
If you grow them correctly that will not happen, I've revegged plenty of times, never get stemmy airy buds, matter of fact, my reveg are some of my biggest monsters. You obviously are doing something wrong.
I can buy Foxfarms has everything needed, works great, lasts forever. Definitely not watered down, too much will burn your plants to a crisp, which is barely any.
I do organic as well, works great, lots of effort though. The problem I run into with organics is the amount you need when you grow...
Your plants are fine, some tip burn is ok, soil looks prettt wet, make sure not to over water.
Not sure how big that pot is but it might be getting close to needing a transplant transplant.
If it's soil you're growing in I'd forget about the PH pen, you don't need it when it comes to soil.
You need to be focusing on school and not growing tinfoil cannabis at 16. I doubt your parents approve of this, scrap this foolishness before you burn their house down ;)
Most likely the nymphs the wind/fan works but they will keep coming back and multiple on their own ! One can give birth to 3-5 and those three to five will do the same thing. I'd get some actual spray on the plants asap ! They will destroy a seedling. Hell most bugs will !
Id pop some more seeds for a fresh start but wouldn't kill it, I doubt you're actually at 7 weeks, let it go another 2-3 weeks, try to get more light. If it hasn't plumped up by then it most likely won't. Make sure you don't have any light leaks as well, I'd go ahead and remove that foil too if...
