HYDRO PROBLEM, HEEEELP!!!!!!!

[Padde]

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.

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.

Looks like the problem I am having but it is because I am growing in soil and my PH is low(4-5.0) and there is a nute block.

Thanks a lot for the tip. But if it is nute block, how do I fix it. It is making me crazy,F hydro. Never hade a problem when growing in dirt. This time have plant in soil also, Arijans Haze... on the side of hydro

Well I just read your post again and the reason mine is the waye it is is due to my soils ph being to low. Yours seems fine. I probably would change your res. water and clean the tub and when you add the nutes, give them 1/4 strength for about 1 week and then gradually increase it. You might be right on the nute burn. I am not growing hydro so I am not too sure. I know you are supposed to mix the nutes in the water 1 at a time. Do you have any pic's of your setup?
