hydroponics
2 white widow 2 northern lights...2.5ftx3ftx7ft..im on the 4th week and had a few questions if anyone would like to give some input..before i begin flowering
-im kind of forced to flower these 2 strains at the same time, does this pose a problem?
-My leaves are very droopy and sagging, but appear to be healthy...very green, thick...i use NPK of 10-5-14 , Bio- Bloom, and dutch masters penetrator...anyways do these droopy leaves put a threat on my yields?

There's no problem flowering different strains together, as long as you realize that they will finish at different times. Your droopy leaves sounds like too much nutrients, so cut back on the strength some. Besides, that stuff is expensive!

why are you using bloom at four weeks of growth?

ya i think it was too much nutrients becuase i woke up this morning and they looked terrible...i am very angry...but not to angry, since this is my first time im learning alot as time goes by, and really would not mind at all to start over...but i paid for them becuase i want the best for my plants....im just trying to make everything as perfect as can be.

i started the flowering cycle 2 days ago and put the bloom in then, and now, they are very schriveled and almost drying out...but not totally yet, im praying to JAH to revive them hopefully....

time for a res change, sounds like you may have a salt buildup that will continue to raise the nutrient level of the feed, empty out your res, and refil with plain ph adjusted water, feed as normal for two days with the plain water then take an ec/tds/ppm reading of the feed and you will probably find it isnt far away from being right for the plants, for seedlings i keep the ec at 1.2 veg 1.6 early flowering 1.8 and full flowering 2.0, then you have to reduce it back again to zero in the last two weeks

hey Non,
what is the conversion to ppm on your post? I have my ppm at around 950, I try to keep ph like 6.5, but it keeps drifting back up to 7 sometimes 7.1 my leaves are sort of droopy too. I think I need a rez change too.

can someone explain to me what a ppm reading is? i am totally lost here...i have them in rockwool right now...anyways i have some sort of buildup in the res...the ph is good and the water is constantly moving around, but im getting some sort of white bubbles floating on the top and i dont like it...again maybe its no problem, but im just asking...

ppm = Parts per million. Your nute, salt, chlorine, etc... content in your water.

A full system flush would definetly be in order from the sounds of things. let 'em go on h2o alone for a few days.

Too hot of a nute mix is a very common mistake that newbie hydro growers make. Soil grower make the mistake too. Also, if one doesn't know the PPMs of the solution, how can one know the strength of the nutes? A PPM meter is invaluable to a hydro grower. Get one at your local hydro store.

is there anything wrong with using strong nutes like 20-20-20 or bloom 10-40-10 in your opinion for soil? should these nutes be extra extra diluted for use? they contain all nutes and micronutes that herb needs. in particular im refering to peters professional. it seems to work, im just wondering if its better to use something else?

edit: sorry wrong thread!

Agree with maritimer. Flush 'em for 2-3 days then start your nutes back at 1/2 recommended strength.

Adjust your pH of the flush water if your make-up water is too far off the mark. I normaly run my tanks a tick acidic, at 5.3-5.8, as rockwool is a bit alkaline. Plain tap water should be close enough to 6.5-7.0 to not bother stuffing around much with it.

Fert-scorched plants will have plenty of nutes stored, don't fear being stingy with nutes when recovering them, at least for a couple of weeks.
