Help me identify the issue with my girls.

Hi community. I have run into a slight issue and I'm having a hard time indetifying what's wrong. I have 5 plants outdoors in soil. 3 are in 15 gallon smart pots and 2 are in 10 gallon smart pot. They started flowing about a week ago at the most so last night was their first feeding using a bloom enhancer. I'm currently running the following nutes:
2.5ml Flora nova bloom, 1ml gh armor si, 4ml gh CaliMagic, 3ml gh flora blend, 1ml gh floralicious plus, and 1ml liquid kool bloom per gallon of filtered water. I got my recipes from the Dude Grows. I usually use about 5 to 6ml of the flora nova bloom but ive been told when adding liquid kool bloom to reduce the base nutes in the beginning to see how the girls react. This morning when I woke up 3 of the 5 pants have some tips curling down on mostly the lower fan leaves. Now the blue dream has had these curled tips for a while now but no other issues presented themselves so I didn't think anything of it. And like I said it's only on the lower fan leaves. After lots of research it was hard to find a reason why the tips are curling down. Maybe nitrogen burn. Maybe over watering. But I doubt it cause I was using the lucas formula which means I used the bloom all the way through which has less nitrogen than the grow. And I doubt it's over watering since I usually let them dry out pretty good before watering again. And in the California summer it's been pretty hot to where I have to water every other day or every 2 days. I know nutrient burn tends to look a little different than leafor tips curling down so I don't think the liquid kool bloom burned the plants. I may be wrong though. I provided some pics. Maybe someone with experience with these GH nutes can shed some light on what I'm doing wrong. They have all been super healthy up until this point. And don't get me wrong they still look really good. It's just the lower fan leafor tips curling down. Thank you for all the help in advance.

That's a warning sign that you are overfeeding. As is any sentence you write describing 6 different fertilizers being used.

Interesting. That's the same formula Dude grows uses and I backed off the base nutes big time. I've been using 5 different products for the entire grow with zero issues. And I even water striaght water two to three times between feedings. I only freed about 1 time per week at the most.

Also from my extensive research most nutrient burn and over feeding tends to lean towards burnt tips. And browning from the outside working it's way in. I haven't found one article the says tips curling down is over feeding. I will flush again and see what happens.

Trust me, downward clawed leaf tips are known very well as a warning sign of over feeding. Different strains handle different nutrient loads.

Nitrogen abundance. Lay off the nutes.

It also looks slightly overwatered and hot.

One plant was showing this while only using the lucas formula. In which I used the bloom forMula for the entire grow which has a lower nitrogen level than the grow. Weird it would still cause a nitrogen abundance. Thank you for the tip.

It happens. My nutes were 3-4-2 and I got a little N tox'd

That's what I thought. But I always waited till they were pretty dry to water them. And in the smart pots in this heat they were drying out pretty fast. Maybe I did over water but I usually let them dry out before I water again

Might be humidity? Who knows? Give them less water or wait longer.

OK. Cause that was my first thought. Nitrogen toxicity. Cause over watering usually shows different signs. But it could show up as curled tips. I was hoping by using striaght water 2 times in between feedings would flush it enough to prevent this.

What you described is showing in the plant. But it was N tox'd and only slightly overwatered.

I was giving them about 2.5 fal

Yea I was waiting till the got dry before watering so I was hoping I wasn't over watering. I will wait for them to slightly droop next time before watering. I also was using a moisture meter to double check the moisture level. I'm in northern California and the humidity is rather low but I has been really hot. So it could be the heat combined with too much nitrogen.

My pots are in 5 gallon buckets with holes through the bottom. I give 1.5-3.8L of water per bucket every 3-5 days.

So, like, 3/5 to 1 gallon for a 5 gallon.

So people on this thread told me they put about 2.5 gallons of water per 15 gallon smart pot. So that's what I was doing about 2.5 gallons per 15 gallon pot. And about 2 gallons in the 10 gallon pots. Then several guys at the hydro store said that's even too light for the 15 gallon pots. They said about 3 gallons min. So this was the first watering that I bumped up the amount of water I gave them.

Not really an issue, the slight overwatering, but it is N tox.

You can water every day outside in a smart pot and not overwater, all depends on the quality of your soil. I'm in 60 gallon smart pots and water a few gallons every day. Another week and I'll be putting down 4 gallons a day. The "let your plants dry out" stuff is fine for indoor grows with controlled temps but complete bullshit for outdoor grows with high heat.

The clawed leaf tips is a sign of overfeeding, not necessarily nitrogen. It is most commonly nitrogen because that is commonly the most applied nute in veg. You can produce clawed leaf tips with low nitrogen levels if your overall ppm is still too high.

What should I do when I get home then. Flush them immediately
