Check run off ph first with any possible deficiency issue. Most cases substrate ph is off and your expecting a lock out. If that is ok. My next question would be do you get the leaves wet when watering? If so it could be light burn from light being magnified through water on leaves. Good luck hope that helps. Happy growing. 🌲🌲🌲👊

Hi !
Er lijkt mij op het eerste zicht iets aan de hand te zijn met je ph, afloop van het water, weinig zuurstof bij de wortels, verstikking ..
Kan je dit nakijken?
Ik zag bij de foto's in je dagboek dat je ook last hebt van spint, dit zie ik aan enkele bladeren meer onderaan.
Heb je dit al behandeld?

Deficiencies? Brown spots, yellowing and purple stemsWhat is this deficiency or maybe toxicity and whats the solution? She is fed with biobizz chart instructions but with every other watering. She is big so I'm guessing I should water with nutes every time? She showed this first week into flowering.

Fan leaf deficiencies during flower. To cut or not to cut?Day 85 Update: G13 has a ton of fan leaves turning fast. Pretty sure it's a PH issue. Should I wait until they're dead to trim them off or get rid of every fan leaf that is affected more than 50 percent of the leaf?

Yellowing leavesLeaves seem kinda yellow on one hand. The bottom right hand corner one looks like she needs CalMag but I'm not sure.
All the photos have been taken under the same light.
Used to over dose the nutrients to prevent burn but continually gave them 1mL/L calmag each.

lemon tree wannabeI think it's calmag and lack of nitrogen but any ideas. I've been busy in the garden so have taken my eye off the ball. She looks in great health with praying full leaves but her colour is off.
Any ideas would be taken with gratitude.
