So about a week ago i sprayed my 3 week old plan t with neem oil. the next day the first two leaves were half brown and yellow and are now almost completely shriveled dry. this discoloration and dehydration is now slowly spreading to the other leaves. 1.was my plant too young for neem oil? (my vegetable patch took it just fine) 2. I have already washed my plant and transplanted it. what else can i do?
How are you lighting em? If they're exposed to light with neem on them they'll burn bad. Its hard to tell what exactly the problem is, but chances are its not the neem oil. Whats the ph? Have you used nutes? This looks a lot like a problem my plants were having with spots and leaves dying. My ph was high (7 - 7.2), so I lowered it, added stronger lights and started 1/4 strength fertilizing. That fixed the problem completely, and all new growth was healthy and fast.
I have them directly under a skylight that gets direct sunlight whenever it isnt cloudy. Ive been using tap water but ill switch to distilled to be safe.
