J1 older fam leaves getting brown spots and yellow...
Athosanswered grow question 6 years ago
It's nutrient lockout due to to nutrient toxicity. Don't feed more than 700 PPM (you are giving them 3 times this strength) just flush and flush and let the plant consume the excess nutes it has

Hi there! From what I can see, your leave's tips are becoming yellow / brown / crispy, this could be a sign of a nutrient-burn, if extra cal-mag doesn't solve your problem you may want to flush her for a couple of days. Also, how far was this leaf from the light? I'll be around, good luck with this beautiful forest!

Overfed P and KUnfortunately i have overfed PK as thought the bottle said 7ml per L but instead was 0.7ml. Noticed tips of leaves the next day browning so checked the feed chart again and pretty much shit myself. Flushed all 3 plants for about 5 mins and now they seem ok hopefully.

Moin, bei meiner Größen Pflanze fangen die Blätter an von außen gelb zu werden und braune Punkte zu bekommen. Ist das ein Zeichen von einer überdüngerung? Alle anderen Pflanzen haben dies nicht. Oder zu wenig?

Brown Spots on my plantsGood morning,
I've noticed a little color change in my 10 day old plants. What could this be? Also, the first set of leaves seem a bit loopy?

Personally I think it's the hydrogen peroxide 12% mix, the hydrogen gave one of its atoms to the neuron of the Diatomaceous earth metal clay. With help from heat

Pest attack. What can I use to eradicate?3 weeks of flowering, and the pests are still here. Can I play Beauveria Bassiana? Or just neem oil?
- The temperatures were very high here, exceeding 30°C, this week it will decrease.
- I have other plants to harvest and I'm going to take advantage and clean the grow.

Calcium deficiency?Saw this little brown/yellow parts today.
She is in BioBizz LightMix Soil and gets 0.3ml/L BioBizz CalMag 3x per week.
pH is above 6.5 .
Today I gave her 1ml/L CalMag.
Was this the right choice?
Is this a calcium deficiency?

Black spots spreading // Need your help!Anyone got a clue what this dark spots could be? It started in a corner of the tent with 1 plant a few weeks ago and now it has spread to another. I suspect pH issues and a nutrient lockout bc of that. Not sure if its the same issue though..Could be an infection as well...

How's the quality?How would you rate the quality of these plants? The dark brown leaves have me self conscious of the roots situation. DIY supersoil mix recipe here: https://pastebin.com/pbxMZysq I've added more dolomite & guano as topdressing and fed liquid calmag and potassium during flowering.
