Unsure what?
Duke_Elakstarted grow question 5y ago
It might be caused of overcompensating Water and/or to often.
Also Im RE uses last crops soiless mix as medium.
30%perlit
30%peat moss in HYDRO claypebbles
40% Coco coir
Dried for 2month before washubg and BUFFERING with cal mag.
WHAT can it be?? Doesnt look good at all?

NobodysBudsanswered grow question 5y ago
Did you rinse and dilute the old coco?
drying actually increases concentrations.. washing won't help if the CEC have gone the opposite direction and have too much Ca/Mg bonded. You don't need to buffer when re-using.. just wash it well and go. if anything is separate, likea layer of hydroton, may want to sanitize that.
anyway, my 2 cents is it is an overabundance of one nute or another -- imbalance. Also ensure pH is 6-6.5, or whatever your ferts instruct.
Fruitgroweranswered grow question 5y ago
The sweet spot for coco is ph 5.8. But you have some peat as well, so maybe 6-6.5? Might be a good idea to add a low dose of grow nutrients and watering less 🌱👍

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

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

New grower with questions about burnt tips, browning/scrunching leaves and some pale/yellow spots!I noticed Quick One had issues with burnt tips and discoloration by the end of week 1 and 2, what could've been the issue?
Apple Fritter is looking sick, brown spots, what is that?
Easy Bud and Quick on have slight yellow/paled spots on their leaves, only 1-2, is that normal?

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!

Cal mag or nutrient BurnI have 3 Automatics.
I made the mistake of planting the into BioBizz Allmix, which is pretty strong for Autos.
Strawberry Gorilla and Aplle Strudel seem to be fine.
My Orange sherbet not so much.
Is this Cal/ Mag defficiency or nutrient burn?

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?
