Browning, curling of Green Crack leaves
happykatstarted grow question 3y ago
Is this discoloration worrisome? Ph 6.1, adding 1tsp calmag to each gal, EC at 1.5. What's causing this browning? Seeing only on the Green Crack, mostly higher leaves, but some lower too. Does it need more or less of something? Leaves look "dirty".

1.5ec seems a bit low for photoperiod plants, they may want more but before doing that check its PH.
Give that they are in soil you may want to raise PH up to 6.4-6.8.
Best Of Luck!

Deficiency?I noticed this spot on one of the fan leaves. It only appeared in the last couple of days. I have been feeding small amounts of calmag and biobloom. I looked at deficiency charts but I’m unsure. What could it be?

The leaves have become glossy and yellowThe last couple of days, the leaves have lifted a bit again and bent the edges, and the leaves are glossy, was it a mistake to keep the light on 24h the first week, or what do the last couple of pics look like? (I have now set the mode to 18/6) so as not to fry the plant

The leaves are wierd shaped, but growing fastHi everyone! Please tell me, is it a consequence of leaf scorch with light, or incorrect watering, or I was very in vain in the beginning added root booster? The big question is, is it worth waiting for a potential recovery?There's nothing like it at google

Weird Curls and HolesOkaaayyy so wtf 😂 I've altered light intensity and height multiple times at this point. I've ruled out pests. I think it's either windburn, heat, light, or a combination of all 3. It's a little concerning seeing as how I think mid flower is right around the corner 😓

Sudden Leaf Yellowing – Lighting Issue or Something Else?Hello! Yesterday, I noticed the top leaves turning slightly yellow, but today it looks dramatic. Check the pictures—leaves are yellowing and drying out rapidly. It’s only affecting the central leaves, so I suspect a lighting issue, but I’d like to confirm before taking action.

First time DWC, day 70, 3 weeks in flower. Nasty rusty spots appear on lower leaves. Is this CalMag or else? Please help understand and fix, thank you :)I'm using TA Tripart, current EC is 1.6 - ph 5.5-6.5. Everything was smooth until week 10. Two weeks ago I started adding Plagron Power Buds and Green Sensation. Yesterday added CalMag to see if it helps, but it doesnt seem to... She drinks a lot, ph mostly goes down, EC static

I wanted to ask if you think this plant has mold or if it's just a major deficiency due to a blockage. I have an indoor plant next door with some plants growing with dark spots, it's in my previous question. Sorry for giving more information, I don't know what would help.

Braune Flecken an den BlätternHallo zusammen,
Ich habe seit ein paar Tagen diese braunen Flecken auf den alten Blättern meiner Pflänzchen. Die Wochen zuvor habe ich gedüngt, allerdings nur mit 1 ml BioGrow, 1 ml BioBloom & 2 ml CalMag von BioBizz — denke eher es ist ein Mangel.
Vielen Dank für eure tips!

Leaves keep turning brown and yellowIt all begann with what I thought was light burn. I then considered it CalMag deficiency. Giving it CalMag did not stop it.
My current guess is too low pH due to strip inaccuracies, so I gave it around 8 today instead.
What do you recon, why could it keep getting worse?
