are my ppms alright?

[shovlboy]

My plants are now all about 2 feet tall, Still vegging them for 2 more weeks. I raised my ppm level from last week 1240, too 1440. Is that to much? I changed it last night.

for vegetative growth, I usually do not exceed 1200ppm. I like it around 1000. Its when they get to flowering that the demands began to grow. But if it doesnt burn...then its liking it.

what brand of nutrietns do you use? I'm using GH

[latewood]

you should be alright. They are pretty mature, I imagine. What size lgiht?
I follow the standard 8ml per gallon each part in veg, and as I recall that comes to about 1500ppm...It has been awhile. I don't measure ppm's much anymore. I have found my "zone"

The lighting are 2 1000 watt bulbs. Im running MH lights right now. The ballast are switchable.

cool make sure you top off with water to keep your plants from getting toxic shock with big lights...more heat will sometimes cause the plants to use more water than nutrient in the mix. i.e. the other night my AC went out...I went in next day and biggest skunk in flower had used 2 to 2-1/2 g of water...the EC was up to 4...and that is like 3000ppm...I believe
I had to just ph the rowater and fill 'er up

anything after 1200 is pretty much wasting chem's in veg,they may tollerate it....but its a waste of money.

for vegetation cycle 1400 is a bit high. 1000 is more like a good number for veg cycle just before you switch to flower. You may be giving it a bit to much N with PPM that high. When you are in the second week of flower you change from veg cycle nutrients to flower nutrients. You don't switch to flower nutrients formula the same way you switch the light cycle. Give them a week to make the change first and you will have fewer problems at the start of flower. A flower booster is good to use at that point too. It does help them kick into flower faster and fatten up the flowers too at the end. A good booster is used only the first week and not again until the last 2 weeks of flower just before you flush.

i dont really get the chance to get my ppms that high in veg, when there about a foot i flower, thats about only a week or 2 with nutes. those are gonna be huge when u start to flower, expect them to be over 4ft

[JackdaWack]

also you dont neccessarily have to wait to change to your flower formula, i would just make sure the ppms are the same when u switch, the plant in theory should flower better if you change the nutes when u change the light cycle. But at the same time it takes time for the plant to switch to flowering however the flowering nutes should help it convert better i would think. If your plant is starting to flower and you have flowering nutes i would think of it as a catalyst. If you are starting to flower and still using veg nutes, i would think it would retard the plant.
