1500 ppm is high. I grow in soilless blend & use Dyna Gro products at around 300-500ppm from veg to flower. 500ppm Bloom formula with my tap gives me 6.2-6.5 ph so I never have to adjust, it’s perfect for me.

Where the he'll have I been at?
I been lurking on this board and Icm for a min but never really commented much.
I bought a pack of nitro cookies way back in 2015 and popped all the seeds. Well, about 6 months into the grow I had a domestic disturbance and lost 4 out of 5 seeds. The last one believe it or not was the keeper. She's picky. A heavy feeder, but she grows rock hard nugs, that are covered in trichs.
I run a perpetual garden and the vegging plants are grown in 1 gallon hempy buckets. After one month grown in a hempy bucket using a very aggressive veg feed schedule. I take clones and start the process all over again, root and grow for one month. They are than transferred to the flowering setup, two 4x4 100 gallon no till tents. I fit about 5 med size plants in one container, 6 if they are smaller. I harvest every 65 days. Here are some shots of nitro cookies, the last couple of runs. I do have older pics but I had mites back than, before I finally eradicated them.
Well that's my long winded story.
Ps I'm still running nitro cookies btw

I've kept the feeding pretty light on my jelly pancakes and still seems to be frosting up fine so don't think you have to slam them with stuff 4 those IG type pictures lvl of trichs. Starting to get a bit of a cookie smell now

As others have written, there might be an issue with too high a level of feed (salt toxicity).
How have your ambient temperatures been? Has it been hot?
How much are your plants drinking compared to average?
Is this damage only at the top of the plant(s)?
There are a couple other possibilities in addition to salt toxicity.

Wk 5 Tropic Heat keeper, funky pina colada terps since wk 3. Decent cookie yielder just running this in a small pot to see how new stuff compares. So far my Tropic Heat is beating out the other cookie cross Rado's Altar Bread

We'll see here soon. I run everything at max.

1500 ppm is stupid high for me . But if that's what your strain takes , it takes. I peak at 1200ppm in flower . Veg 850 900 . Is that the ppm of your run off you may have salt build up. Ya it's summer , I had a few strains catch root rot and die . It's really tricky this time of the year to much water and you get damp roots to little could kill the root zone. I would flush with water and let dry out a bit . Make sure you don't have root aphids , they are similar to fungus knats in looks and raise your light for a few reasons . Stress and heat.
A huge tell tale of the plant being way to hot from the 600 is the bottom will be nice and caked up with trichombes while the top isnt . You have to replacate those seasons.

What's the max? Dyna Gro is strong, my plants get really dark green off this stuff. Almost too green than I want them to be so will ease up more in flower. Still learning how to use these nutes but im set on using them for a good while

Most high end hydroponic nutrient company's are using the same types nitrogen phosphorus and potassium (ie calcium nitrate ect) to get there desired n , p and keep number . The numbers and percents may be different but the form of nitrogens used are usually very similar. That said I usually Feed at about 650ppm in veg max if the strain wants it 850 9. Some times it could be allot less . You can also kill a plant from excess N. So be careful it's not one size fits all. I have a chemd x gsc from csi that won't live on 600 ppm it's nitrogen hungry but if I feed my train wreck cut the same ppm I get clawing from oven feeding.

True they are the same for most part, was using just Floranova Bloom for the longest & tried Mega Crop but just having better results with Dyna Gro. I'm running different strains & so far so good. The only hungry plant I have is my chuck which is a sativa beast, the OG Chem, Cookies & others are fine with 500ppms max. Havent seen clawing plants but I will still scale the ppm down lower until I find a sweet spot

You guys have made some very great points that have been helpful. Couple things. Yes my lowers indeed much sexier than my tops. The salt toxicity thing I think may be a game changer. I don’t know if my nutes have synthetic salts but I’d bet they do. I also don’t often water to runoff because plants are in huge pots and it takes Atleast 2 gallons to achieve runoff. I’ll try to clip my light to just carabiners and get rid of the ratchet hangers al together.
edit flower tent is probably…. 90 degrees towards the tops? That hlg 600r cranks out watts and heat man…. I have 6” fan and filter with duct work going through roof but can’t get it any cooler realy. Been hella hot outside. Plants are dying for water every 48hrs max. They’d love it if I’d water every day just don’t have time

If they get dry definitely lower the ppms. My 4x4 is in the mid 80's with leds & I grow in small pots so they get thirsty quick. I can tell my little bit of burnt plant tips is from dry medium. I want to set up a drip but I actually like hand watering tho it is a pain/chore

Ahhh so possibly it’s getting real dry like a DWC bucket and whatever liquid is in the pots is highly concentrated and toxic if they get real dry right?

I have digital thermostats hanging under my lights at right above the canopy. That's your true room temp . Some one once told me your only fooling yourself measuring it some where else. I'm not saying that's what your doing just saying if your not getting temp measuments around there it defeats the purpose.
I don't grow in soil I'm not sure if there is a way to get a ppm reading by your root zone but it may be worth looking into . Ppm that high I would just give water for a few waterings. If it where me I would dump my reservoir and give to straight water for 48 hours then add my nutrients. Good luck what ever happens. Summer sucks.

I would bring it down to like 750-900ppms

Yes exactly. Dry spells are good for vegging plants making roots grow but in flower its best to always keep them on the wetter side. That's why I stopped using fabric pots they got to dry for me & I went through to much water. Now I can pretty much water my 4x4 with half a gal of water, small plants but tent is packed out now
Summer does suck for me as well. I usually have to grow sativas so I don't get mold or grow small plants

I thought you had a hps hid. My fault. Temps should be allot easier to control with a led light , can you move the drive outside the tent . I bet you could buy the proper aviation conectors and rewire it if not.
