started grow question 4y ago
We are in the middle of week 6. I think there is a deficiency or a toxicity. I couldn't understand why. Could you please check?

If I had to guess a bit of nitrogen excess, perhaps slight calmag deficiency.

Hello. I have a question. If there is a risk of nitrogen deficiency on the leaves, it looks like something is missing. pH 6-6.5 on the leaves you can see slight discoloration.

Raise PH of soil? Is run off actuate reading of soil PH? One of my plants might be getting sick, I need a fix for this ASAP!
So quick question... how would I go about raising PH of my soil. I just took a reading about 5 mins ago from my runoff and it was like 5.8!?! It’s never been 5.8, and I do have a little issue with 3 of my fan leaves on one plant. No soil PH meter. Just flushed them 5 days ago...

N issues
This girl suffered from N deficiency very early. So I gave it nutes. Nutes gave it N toxicity. So I flushed the soil with ph’ed water. You guessed it, it’s lacking N now. The problem is the pot is still very yet and heavy so I don’t know if I should water with nutrients

Water
Is it bad to make my water ahead of time ? I mixed my nutrients (big bud, formulex, bud candy & molasses) in with the water & have let it sit out for over a day. I heard letting it sit out gets the chlorine out (I put a towel over it though so my cat/other stuff would get in it)

Rust spots
My lower leaves are showing rust spots along the veins. Appears to be a magnesium deficiency but I am feeding cal/mag. I also growing in ocean forest soil. I’m starting to think this is nutrient lockout? I’m feeding a low dose of nutes(250 ppm every few days) soil could be hot?

Nute lock or nute deficiancy?
had some yellow leaves start to pop up on one of the girls. Looks like a nute lock that we will address with a PH water flush and then slowly wrk them back up onto the feeding schedule. Didn't check my Ph and my guess is Ph went too high in the soil.. Thoughts from my gurus?😇

What deficiency / excess is this?
Killua feels alright but the tip of some of his leaves looks like this (see photo). What could it be? Currently feeding her with 1 mL/L BioGrow, 6 mL/L BioBloom, 3 mL/L Top Max. Never gave him anything different. Also, big fan leaves are healthy, only some leaves randomly are ill
