Maybe, but that thing looks rough. Either you started with battery acid in your soil, or you have bum genetics. Youāre only a few weeks in, Iād restart my grow.

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 static1y ago

2 out of 5 plants are showing signs of nutrient burn? Soil growHi, I am seeing clear signs of nutrient burn but only on 2 out of 5 plants. I feed them organic nutrients, following the chart that was provided by BioBizz.
Why are they still showing burned leaves? I watered them thoroughly until the runoff was clear. But leaves keep burning.š¦Week 9

Day 14. Since day 12 a brown spot has appeared on one of the leaves of the first node, spreading little by little. Because of the symptoms, I think it's septoria, so I've sprayed neem oil to see how it works for her. Someone knows what can it be?Week 2

Leaves brown down the length of half the leafI have some leaves that have gone a bit brown down one half, but along the length. See them in Day 40 pics (I have added a extra comment there). Does anyone know what that is? I was thinking maybe it is just the bits that have been sitting under other leaves, but I am not so sure6y ago

What deficiency is this?Can someone tell me what this is being caused by? My suspicion is a potassium/ calcium deficiency? It's affecting mostly the larger fan leaves. Also, affected leaf stems are turning purple. Posted a pic of one of the leavesWeek 6

Check out my week 7 update for more info. Only one plant in the tent affected so it's really bugging me?!? Thought it was overwatering. Left them 2 days between feeds and they are bone dry and pots are light. Any suggestions or could it just be a trait of the Pheno?Week 7
