i've always been a light feeder compared to a lot of people around here. right now i'm growing in peat mix with 20% extra perlite added, in 10 gallon smart pots. in veg i'll start them at 100 ppm as seedlings, when they get three or four sets of leaves i'll bump them up to 200 ppm. they stay at that till a week before they get moved to flower. i'll give them 250 ppm that week, then i bump them up 50 ppm per feeding till i get to 400 ppm. that's as high as i go with most, a few strains seem to like more, and i'll go to 500 ppm with them. i'll stay there for 3 or 4 weeks, then start dropping slowly. by the time i harvest, they may be back down to 100 ppm. i'll give them the same thing in flower as i did in veg till they stop stretching, then over a couple of feedings i'll switch to flower food.

Sweet thanks buddy.
I’m in coco perlite mix on week 4 of flower and there getting 600ppm today that’s me giving just over 1ML per litre of a 6 combo feed, Also a velokelp foliage spray at the stem and bottom stems of all my colas also a bug spray.
Flush once a week just pH water.
Would u start to come down on nutes at this stage or carry on for little longer,

Today’s pictures and temps.
Just hope these fill buds fill out only 4 week left 3 week till flush hv between 12 and 8 tops per plant.

i keep feeding heavy till they get about halfway through the "swell", then i start cutting back. that usually gives me about three weeks to a month to drop ppm

So I’m just wondering what you think of these leaves burnt/heat stress or something else.

mostly looks like senescence, the natural fading that comes as the plant ages. might be a little calcium deficiency and maybe a little P deficiency. might want to check your ph meter and make sure it's in range.

try to stay close to 6.1 ph in coco, you can drift up and down to prevent lockouts, between 5.8 and 6.3, but always come back to 6.1
don't flush right now, they don't have toxicity, they have a deficiency, and i don't think it's a lockout caused by too much of something else. you might give them a little extra cal-mag, but just a little. and check your meter, get some solution and make sure it's reading correctly. a teaspoon of baking soda in a glass of water ought to be very close to 8.3, milk should be around 6.6, wine or beer should be around 4.
they make solution to test them, which is more accurate, but you can use one or more of the above to test it till you can order some solution. ph is important, one point is ten times as much as the previous point, so the difference between 5 and 6 is 1000 times, not 1

why check runoff? if you put it in at the right ph, the plant will take what it needs, and the rest will runoff. you're never going to get the same number coming out as going in, the plant uses part of the nutrients in the water and that will change it. you're never going to get consistent run off numbers, and they shouldn't be consistent, the plant is growing and changing and releasing chemicals from its root system. just make sure your meter is accurate, and put it in at the right ph range.

Ye I do hv a good pH pen cost me £50 I’ll leave to flush like u said I ain’t got a toxidity.
I use solution to cal my pen all the time too my water is like 7.8 once nutes added goes to about 6.5 then I drop the pH down in.
If that’s the case mate I’m bang on all the time then going in is always 6.2 no more no less, I though i had to check run off and what ever that was coming out I had to make that 6.2 but read something on the internet wrong I guess

yeah, the plants wll take what they need out of the nutes, and that immediately changes the ph from what you put in. unless you've done a good bit more study than me, you don't even know exactly what the run off numbers mean. i'm just getting to where i have an idea, and it still confuses me sometimes. the only time i check run off ph is when i have a major problem and i can't figure it out. if it's WAY off, i might flush with water ph'ed too far the other way to even it out, but thats a pretty extreme measure, and i'd have had to tried just about everything else i could think of first
