Superthrive for stunted clones.

ive had these 9 clones now for over 4 weeks and have had a hell of a time trying to get them to grow. im using ocean forrest soil and have them under a 400 watt mh 18-6. i flushed them last week with reversed osmosis water and fed them super thrive and growbig at half stregnth. they had a 3 day growth spurt and since then have reverted back to slow growth. i want to test the ph of the water but will have to wait until the soil is dry to water.
should i be using superthrive on every feeding or every other? ifeed them grow big every other watering and the ph of my water is 6.2. the water i had been feeding them from the store down the street turned out to be 8.8 ph! (its funny though because my last grow i fed them the same water and never had any problems untill i flushed them thier last 2 weeks.) so im guessing the ph is still high and my clones are having problems uptaking nutes. that would explain slowed growth.

flush with 6.0 water or RO water with a flush like flora kleen, make sure there are no carb or sugars in the rinse agent you use. use 2-3 times water as the size of your pots/containers and drain well... test the run off for ph, and ec. make sure your temps are up to par for proper growth as well... ocean forest is "hot" soil meaning you should be careful with your nute schedule for it is loaded already. happy growing

is it ok to ph my tap water and feed them even the well water we are on has amounts of harmful minerals and stuff. like i was saying, i flushed them, but with high ph water and they were all looking so good and growing for once for only 3 days. now they are barely growing and the leaves are once again turning a very light green. don't know what to do!?

overwatering let them dry out before u wate bet that makes em pull round

Ohh, how come? I use a rinse agent recommend here that does list sugars as one of the ingredients.

Alright man after checking out your pictures of your clones, i hiope the ugly ones are still salvagable. If your light is not with in 12-18 inches from your clone its going to be hard for them to grow. Like someone said earlier you shouldnt have put nutes the plant yet because they are just establishing a root system. Keep watering the with water from a ph level from 5.8 to 7.3 and you might be able to save the bad ones. Dont nute them up for six weeks after they have established growing...or you could keep doing what your doing your choice

I have the same issue. It looks as though you have a root problem "pythium" (Pythium root rot is a common crop disease caused by a genus of organisms called Pythium. These are commonly called water moulds. Pythium damping off is a very common problem in fields and greenhouses, where the organism kills newly emerged seedlings.[1] This disease complex usually involves other pathogens such as Phytophthora and Rhizoctonia. Pythium wilt is caused by zoospore infection of older plants leading to biotrophic infections that become necrotrophic in response to colonization/reinfection pressures or environmental stress,[1][2][3] leading to minor or severe wilting caused by impeded root functioning.[1][4]). However, in hydroponic systems inside greenhouses, where extensive monocultures of plants are maintained in plant nutrient solution (containing nitrogen, potassium, phosphate, and micronutrients) that is continuously recirculated to the crop, Pythium spp. cause extensive and devastating root rot and is often difficult to prevent or control.[1][4][5][6] The root rot affects entire operations (tens of thousands of plants, in many instances) within two to four days due to the inherent nature of hydroponic systems where roots are nakedly exposed to the water medium, in which the zoospores can move freely.)

Let plants almost dry out before watering again, Vit B or Aussie tonic, Enzyme to eat up the dead decaying roots in you pots, and BioGold to create a healthy bacterial culture in your pots. If none of the above works, Start over, but first do a huge clean up of you space and containners. Be thorough.

Root system sucks.
