Heavyweight fast and vast problem

Hello thank you for looking at my post. I have a heavyweight fast and vast Autoflower at day 25 and I just started feeding nutes in 2 feedings ago(6 days ago roughly). I'm using promix all purpose seedling starter in a 3 gallon pot. 450w led grow light. Using flora Nova bloom at 2 ml per gallon of distilled water with 3ml of calmag + and pH up to pH it at around 6.0-6.5 (using drops. pH pen is coming in soon.) it's having some issues at the end of the leaves and it seems that a newer leaf has some holes in it. I also noticed random purple stems on a separate branch. I'm worried. This is my first grow and I'm not trying to over feed her but I think I might have with 2ml per gallon? I could use the expertise on this and is very much appreciated. Thank you.

I also have a thc bomb Autoflower growing and it has been having problems since day 15. Yellowing of bottom leaves and curling tips with alot of purple stems. She isn't looking too good compared to the fast and vast. Here are some pics. It seems that the growth has stopped and I am giving it everything I am giving the fast and vast. Is it needing more N? I don't want to give it too much N. I sprinkled some bat guano on the top of the soil and gave it 2ml of flora Nova bloom per gallon. Anyone help?

I used to use Flora Nova on autos and it consistently burned like 30-50% of my plants until I cut way back on the feeding, but then my yields were shit. Finally I switched to Fox Farms Tiger Bloom and Big Bloom and it was the best decision I ever made. Flora Nova is harsh stuff on autos for whatever reason. But all my Auto strains (and I grow quite a variety) LOVE Fox Farms, and the Big Bloom allows your plants to take heavy feeding compared to other products by stopping nute lock-out. My plants have never looked more healthy, right up to harvest when most plants have yellowing leaves with brown tips and rust spots, mine still look green, I love this stuff. When I switched I was growing 60-Day Wonder and getting about a half-oz/plant, and it jumped to 21-25 grams per. Other plants respond even better, like Cash Crop and auto Pineapple Express. I feed once a week and the only other thing I give them is a tbsp molasses. Reading this you'd thing I work for the fucking company but I'm no shill. Just telling my experience.
Hope this helps...

Consider "nutrient splash" on them lower leaves - this happens when you get your watered nutrients on some leaves, now the upper leaves. I f leaves look like a claw you have to much "N" (nitrogen overload) auto's like a 10-5-10 (veg) and 1-2-1 (flower) remember once you see a problem you are all ready 2 weeks behind in fixing it

hows the heavyweight going?

I want to thank you you all for your input. And the heavyweight is doing amazing! Still has some of the rust edges but it's not on any other leaves only on one! It just started to flower a little while ago and they are in day 33-34 I'll post a pic for everyone to look at! I am feeding her 3ml of floranova bloom and 2.5ml of calmag+ and they seem to love it. I trimmed a couple of the dead leaves on the bottom of the thc bomb and it seems to be improving. I'll post a pic of that too. Thank you for your views!
