The_Dudestarted grow question 5 years ago
I have gone overboard with Nutrients. Soil PH went down to 4.5. Flushed soil and PH back up to 6.5 - 7. Getting some brown splotches on both plants but only on the older "first" fan leaves. Wondering if that is just light burn. Plant is much happier now. Backing off Nutes :)

Looks like you had an excess of phosphorus. Think of Phosphoric acid. This caused the big ph drop and caused nutrient lockout. Looks like a good save on your part to flush her hard. I would keep an eye out for cal/mag deficiencies in the newer growth over next week or two since you did such a large flush. Losing the lower fan leaves is no big deal she'll be growing more anyways. If you have a TDS meter it wouldn't be a bad idea to keep an eye on the run off ppm. Check your runoff ph also you can wind up with the ph bouncing back down if your using guano. Best of luck brother

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

Copper spots on mature nodes. Day 64I am seeing some copper colors starting to come out on some sugar leaves near my more mature bud sites. Started today on day 64. I have been following fox farm nutrient schedule and watering every 3rd day with PHd after adding nutes at 6.2.
Is this normal or a nute problem?

Few splotches, anything to be concerned about?Thinking this is because of the too humid couple of nights i subjected the girls to, by mistake. One morning the leaves were dripping wet, and in the propagator the humidity was insane like 98%.
Have since taken out of propagator and starting nutes on Saturday.

Somethings up with my baby girls!?Help! I have no idea why my girls aren’t happy?!?! Their leaves appear wrinkly (like when you stay in the bath too long). They were stretching when they first sprouted so I moved the light down and turned up to 💯 Shouldn’t they be a bit bigger by now?!
