What’s wrong with my plants?

Hey guys, I’m brand new to growing, I was spending waaaay too much money on smoke, so I figured I’d try to grow my own. This is my first grow and everything was running smoothly but now that I am noticing the little hairs where the buds will be, I’ve also noticed some lower fan leaves with rust or burnt marks on the edges and working its way into the middle of the leaves. I’m using Black gold soil in 5 gallon pots. The two strains are: Glueberry Auto and Amnesia Haze Auto from Expert Seeds. Both plants are 28 days old. Same soil and ph water and Ff trio (grow big/big bloom at about 1/4 strength) no tiger bloom as of yet. I’m not sure if this is a ph issue or mute burn. Soil ph in both is about 6.3-6.4. The closet stays between 78-81 degrees. I’m located in Florida so the humidity is always around 45-65% w/o humidifier. I know I need stronger lights and I am currently waiting on them to arrive. My soil now is really dry but I don’t want to give more nutes and have heard conflicting stories on flushing autoflowers. I don’t want to kill my plants. Any and all advice, criticism, etc. is welcomed. I want to learn to do this right. Whatever additional details you guys need let me know. Please help guys. Pictures are attached.

I am no expert here but since the bottom leaves look damaged and the top/bud site looks great I can only assume you've got a mobile nutrient deficiency. I saw you only give 1/4 strength and you are not using tigerbloom.. I would up your nutes to 1/2 and add tiger since they are budding and looking for the benefits of bloom fertilizer. Unless you've solved your issue by now but thats my 2 cents. I use "super soil" but still add the FF trio at 1/2 every other water (with compost tea every 3 weeks) and I am having great results so far. Good luck!

Flushing is bad. Giving one round of pH'd Cal/Mag water isn't.

Your girls in flower and that's exciting.

One round of Cal/Mag water shouldn't contribute to decline since you're in soil and at the worst, you miss a week of nutrients. If the issue continues, you know that you need to up your nutrient game. If the issue sorts itself out, the one week of pH'd Cal/mg water cleared a salts build up.

Thank you so much for the input! I was just reading on mobile vs immobile so this is right on point. The Glueberry is doing better, or has not gotten worse. The Amnesia has one more leaf that looks like a P deficiency from the other posts I’ve found on this site. I think I’m going to up the nutes and include tiger bloom for the Glueberry, and the amnesia maybe a round of ph’d calmag water. Thank you again! I’ll post more pics later showing results.

This is what I am going to try for one of them and see how it goes. My leds arrived yesterday and I have those hooked up about 18” above. (Is that a good distance for this time?) I also read that plants under leds will need more cal mag? Is this right? Thank you for the reply, I appreciate the input, feeding them today...fingers crossed!

I know next to nothing about LEDs. There are some amazing and knowledgeable people around here that could write books on the subject. I'm suspecting from what I've been reading is LEDs and leaf surface temperature are important so make sure you check people's history when they talk about LEDs to make sure they know their shit.

What super soil do you use? I was interested in going trying this but have seen where it can be a little hot for some autos. Is there a way to adjust it? If not I have some phantom cookies photo seeds that I can try. Thank you again!

Most definitely, I have found some people on here who need to write a book! I’m reading everything they post. Appreciate the advice and convo! Sooo happy I found this site!

7 weeks into my first grow I have used nothing but LEDS, As far as height goes I would get a decent quality light meter that goes up to 200,000 lux and do a little research ( i don't have notes on me) for the best lux/lumen values for your plant and base your height off that as long as you are not getting heat stress.
