HYDRO PROBLEM, HEEEELP!!!!!!!

System: Hydroponic, ebb and flow, 40 liters tapp wather. Nutrients canna substra flores. Day temp 26-28 Celzius. Nitgh temp 22-24 C. PH 5,7-6,1. Nutrient temp 22-23 C. Humidity 55-60 %. Ligth 400 hps. EC tryed 1,6-2,0. After 4 days of flowering the problem acured.
I thougth it was a nutrient burn, so I took EC down to 1,3 - 1,6 , that did not help. Using magnesium (epson salt). EC of the pure wather is 0,06. Wathering every hour for 5 min, have a sirculating pump in solution. Problem acure 4-5 days in to flowering, after two weeks it gets worse. Buds are very tiny. Have had the same problem for 5 harvests. I have tryed a number of things, but nothing is helping my plants. I am out of ideas. (Newbe in hydro)

Please have a look at the pictures and give me your comment. :thumbsup:

Pictures where taken 6 days into flowering. Notised the problem 4 days into flomwering. Growing Blueberry, K2 , Blue Mystic , and some cross that I got from a friend (Shiva Shanti X Big Bud) and she is doing the best of them all.

Now they are 2 weeks in to flowering, and they are not god. I´m spraying them with magnesium for to days now, but no result.

Can't tell from piks...too animated. peace

Ja I know. I´ll try to get better camera. Poor girls, they are so sick. Never had prolems in soil.....

Well I read your 1st post again and I can say...You should add airstones to your rez for more oxygen.

What kind of medium are you growing in.
usually ebb and flow growers water 15 minutes on every 2 hours.

Your whole problem could be the medium and the water schedule. Get back to me, I'll try to help.

I tried a lot of different water schedule, everyting from every 3 h for 10-30 min, and every 2 h for 12-15min, but no result. That way I desided to try every h for 5-7 min. I have a pump in the res for better circulation of oxygen. And the medium, I dont know how u call it on english, but stons are light with a lot of houles. I`ll take a picture. Thanks for helping

Hi Guys
What in your tap water?Try useing distilled water.What kind of nutrs are you useing? If useing a grow/boost/bloom nutrs are you putting the boost in frist?
You could be locking up the nutrs and the plant is takeing up alot of the salts
and locking out the rest.I had some of my girls start to trun yellow.I used
Revive by advanced nutrients and that fixed them.But be sure to mix the boost in the water frist. hope this helps .keep us posted on how it does.

yeah...that's another couple good ideas...peace

Our tapp water is soft, (EC 0,06), and I read that soft water contains less then 50 milligrams of calcium per liter and should be supplemented with calcium and magnesium, just thinking to try this. In the past we tryed to boil water, and use water filters, and to change nutrients from Canna Substra to General Hydroponics, but no result. With General Hydroponics it was even worse so I`m back to Canna Substra. For now dont use any bloom boost, using canna zym, rhizotonic and epson salt. Just got a hold of aditional calcium, mag and potasium, from canna. And have pk 13-14 to use in 5 week of flowering.
Changing solution today, will try to add calcium and mag. And I´l change watering schedule. Thanks

SMOKE WEED EVeRY DAY

Have you ever flushed for a day or 2 just to clean them out...and then add new mix.

Lots of people flush in transition...It doesn't hurt you or stress the plants either...they feed off stored elements, if there is no nutes in the water. later
