Heavy feeders?

I keep hearing about people pushing their plants over 1000ppms some close to 2000ppm (.5) iv worked with 4 different strains one of Which is blue dream A notorious eater... I’m in week 4 flower and anything over 650ppms and my runoff climbs up 50-100ppms over influx...another strain iv worked with is black widow iv vegged them as much as 10 weeks from seed could never push past 550 in veg and then 3 weeks of stretch I could hit them with 800ppms day 1 of week 4 and overnight they slowed down (I measure ph and ppm run off every day2x) feeding I had to lower them back down to 600-650ppms...how the hel are people pushing plants with that much ppms? Are they really eating that much or do the has a higher tolerance for hot root zones?

Bigger the plant more the feed. A 3oz plant is going to use less food then a 10oz plant.

That’s one factor. Another I’m aware of is the transpiration rate due to low humidity. The lower the humidity the faster they transpire leading to increased thirst. This means more nutrients are taken up and can burn the plant when otherwise in a more humid environment it could take more ppm.

This is how plants can just ‘burn’ when feeding remains the same.

Ok that clears things up then lol I didn’t think about that my tent runs 84-86 rh45-55%

I have GG4 that was upto 1400PPM the last week of flower. Outdoors all my plants are taking 1200 easily. I believe you can't do this in hydro because there are no buffers to regulate things and slow the uptake. I only ever managed 750-800PPM soil-less. Also plants eat way more bloom nutes than veg. I only feed if needed in veg. Then 950 is as high as I could go. Keep learning and tweaking.

I run coco Dtw this explains everything now lol

Also strain makes a difference says blue dream has a higher nute intake capacity than most plants without burning

I hope so lol
