Nutrient strengh - when is a good time to go 100%?

[DrGreenThumb]

Hey everyone,

Thought i would quickly ask:

When is a good time to switch to full 100% strengh nutrients during the vegetative state on a hydroponic system? (holding 3 flowers being watered at approx 1 min on 4 mins off)

my plant size is currently about 7" tall, week 4 from seed and they are full with leaves, strong stems and rich green foliage. we had a problem with nute burn about 10 days ago (50% strengh), we sorted it by changing the watering system to a less frequent watering time so the roots got some air. This 50% nutrient mix has been in place since seedlings (yeah i know i shud of used just water.. i was a bit green before i discovered this forum).

But, as i said, plants are looking very full and strong now, so when should i bump up the dosage in my resevoir to 100%? or should i go up to 75% for a week then 100% next week when i change my resevoir.

Sorry for the long post, but i wanted to explain what the situation is so you guys can help me to the best of your hydro knowledge :)

Any feedback will be greatly appreciated

:peace:

It's better to use less than you're supposed to than more. Some strains don't like alot nutes, some can't get enough of it. It varies with strain I would say. If they look full and healthy at half strength, don't fix what isn't broken. Good luck.

Like bombud said but if you want to increase than do it slowly until you see signs of overnuting than back off.
