This is my first ever grow. Having tons of fun but I’m running into my first problem. My plant is just over 3 weeks old and starting to see some weird spots. I know it’s a basic tool but I do not have a Ph tester, but I’m doing deep water culture using distilled water and advance nutrients grow perfect ph so I’m thinking that’s not the issue. Using a 100watt full spectrum led with 18/6 lighting. I took some macros of the damage. Would really appreciate some pros extpertese and guidance lol. This spots are only on the first pair of true leaves and have yet to spread to anymore. Personally, it looks like something is eating the leaf but it certainly doesn’t look like a mite.
Ph level I’m thinking.. it looks in the leave rather than on top.. when my ph is high id get some of that.. my tap water comes out at 7.5 but I’m on a mtn Sent from my iPhone using Grasscity Forum
Well I tested my mix and it’s a 5.6 so it really should be fine, and in these last few days my baby has gotten derastically worse. The leaves aren’t showing a lack or too much nutrients and I’ve got plenty of light. Roots are still white. Could this be a result of too small a resavoir, it’s around 3/4 gallons? Also have it oxyingated 24/7. I should mention with that this is a super stealth strain that’s only 8-13 inches tall
