It looks a little pale too what kind of light are you using? Rhino skin or a silica additive works well for pests. Here’s my humble grow . Had heat issues and spider mites. I’ll still get at least 3 oz off it. It’s got a month to go
Yeah neem oil then repot in finer soil. Big chunks don’t help. Fox farm works pretty good. Don’t over water or over heat it should come around. You’ll have to deal with spider mites
I don’t do metric.ppm is what I use in North America doesn’t matter. I don’t know about your setup. 35 gallons you must be doing 7 plants? Doesn’t matter because I do know root rot lol trust me. If you don’t clean every week you’ll get it.usually the last of weeks of flower and your plants...
It’s fine your a week into veg. Bubble some h202 diluted about 50/50 (or flying skull) with cool clean water for an hour a week . The bacteria is always there your just setting it back too much to grow by flushing with cleaner
