Overcrowded?

Great for flowering, my Fluence gives 1550 ppf and around 1200 useable ppf. I hang over 3 ft above canopy and cut hours to 16 for veg and still stress them. No dimmer. 400 to 600 should be close for veg. My 600 w 4x4 light veged best at 30% power. Do what you want as it's your grow. I only know from trial and error. Pic at 28 days from flipping.

These led lights are definitely tricky for me to dial in just the right power and height. You're gal looks perfect. Something about 1 big ol girl. You're right, guess ill crank it up a little and see how they respond. I just did my last top dress for the rest of flower. Hopefully with the tea it's just cruise control from here. I can't wait for my 720w bar led to get here. I got a new batch of decent breeders in solo cups for my new 5x5 set up.

I bumped up my lights to around 700-1000 ppfd, on my top buds based off photone... l guess lux meter will be more accurate. But based off yellowing on some of my top leaves. Am i over doing it. Buds are packing on just fine. Im technically only 19 days from pistils showing. But some i assumed since some leaves were praying and some were normal i figure why not turn it up. Some aren't as healthy as I'd like. So would y'all recommend turning down the lights?

Pictures in natural light are more useful. LED lights don’t show what the leaves really look like under natural light.

It looks like the leaves have a nutrient deficiency going on causing the deficiency. I’d be willing to bet the yellowing was going on before the increase in PPFD. Stronger lights will also increase nutrient demand.

Looks possibly like a phosphorus deficiency. If the lights were too stronger typically the leaves would sag/show wilting from light.

You're definitely right, i Had top dressed before flower. Guess it wasn't enough. A tea last week, and bloom top dress. Hopefully the tea helped immediately until the organics break down. I been holding back because it seem like every time i fed recharge I'd see tip burn on new growth. I'll do another tea this week. I don't want to. But I'll give synthetic if i have to. I'm to impatient with organics when deficiencies pop up. Today is 29 in 12/12, so maybe 21 days since pistils. First time growing most of these strains. But 2 strains i have grown and they seem to be where they should be at.
